Here's Why You NEVER MESS WITH Your Factory Fuel Pump!!

[@montejones5788]

Take it from a technician with more than 30 years experience. Never ever use a Shop-Vac to vacuum the dirt off of the sending unit or anything else on the fuel tank! Fuel Vapor gets sucked into the vacuum and the electric motor inside the vacuum can ignite the fuel vapor in the vacuum, then you have a problem. Use a plastic brush and scrub it if you have to and blow it off with compressed air. If you're working in a home garage and have a gas-fired water heater in the garage like some homes do shut the gas off to it make sure there's no pilot light, fuel Vapor will accumulate in an enclosed space soon as you open the tank.

One thing I've learned when it comes to getting fuel pumps nowadays is to never give them your old assembly as a core if they want it until your absolutely positive that you are happy with your new one. Also it's extremely hard to find quality parts nowadays, I always try to stick with oem parts especially with fuel pumps but it really depends on what I'm working on. A lot of times I'll get complaints with new fuel pumps that the gauge isn't working properly like theres still tons of fuel left when it reads empty is common or it's really noisy and doing weird things etc.. a lot of the time what I do if I have to get a new aftermarket pump I will try to reuse as many original parts as possible from the old one like the sending unit for the gauge if it was working. Also what I've done when the oem isn't available I'll take the old pump assembly apart and try to get a part number and information off the pump itself to get through the pump manufacturer like Bosch, walbro etc.. most everything you get at the normal parts stores is just junk, it either doesn't work right or fails quickly. It's gotten really bad.

[@warrenpuckett4203]

DO NOT let your gas tank go Below 1/4. The pump uses gasoline as the coolant. Do NOT fill past 3/4 tank. That causes the evap canister to fail. AS for the Envoy. It has GM dashboard illness. I call it, will fail engineering. It is designed to last long enough. Like 150,000 miles(she dails it up. you dail it down, maybe not) or a bit more. By then your wifey (the dails it up person) will want a new, in style , cute car. Yes that is part of automotive design. GM don't care. If that was 7 passenger. A lot of them got stolen. Worth big bucks in Pakistan and other countries in that area. They have dual Front and Rear A/C with separate controls. About 50% of the 7 passengers also V8 to make, the 6 cylinder Impala and Camaro, go fasters, go faster. I still have a operating 5 passenger 2004 Envoy. One of the last no buffering, 460 A/C vehicles.(60 MPH 4 windows down). The 7 passenger got stolen. The I-6s wont fit in any thing else. Really good engines, not anemic. Maybe a bit too good for a Silverado work truck? Really who would by a all the gadgets, I-6, not for work truck? Yes 2 cylinders less wieght 295 HP and plenty of low end torque. Not enough? Turbo charge it. I guess 500 HP should be enough with small turbo? But you gotta have a V-8. Because it is cheaper. I heard the Brooklin Bridge is for sale. As for working on the Envoy gas tank or Filler neck on your back. It sucks. The filler neck even more. Especialy when the original spare tire is still in place 15 years later. As in frozen by rust in place. 4WD / AWS is great. Kill a tire with 40% of the tread left . Buy 4 knew tires. So what is the full size spare for? Ballast. Maybe why you put the spare in Corvair in the front? Might also help with not getting the license plate pushed into the back seat into the back seat. I am not a mechanic (drive train) any more or a engineer. I did do pre-production vehicle testing, when I got to old to wrench for a living. Engineering: What do you mean it drives like there is a flat spot in the carburetor linkage? FWD sucks money when you got to fix it. Cab forward also sucks money.

[@michaelnelson9140]

Most Japanese cars and some European cars have a removable cover that gets you access to the assembly. I don’t know why u.s. vehicles don’t do this. I suspect their throwing a bone to repair shops, as most people won’t do this job in their garages! It sucks dropping a full fuel tank! I ‘ve done many! On mY 98 k 1500. I cut a hole in the bed floor when I needed to replace the unit. Then I made a patch the covered the hole. It’s my truck, so when I’m done with it, it will be junkyard bound.

[@forreststrong797]

@@rack1850 they ask me for a core on certain ones very rarely and its always the assembly not the actual pump, you are correct it's not very often and I'm not sure what they do with them. Most of the time the core issue comes up is when I do a fuel pump that someone else just replaced and when I ask about the old one they say they gave it as a core. For example last week my friend did a fuel pump in his 1998 grand cherokee and it's giving him problems then when I asked him where the old one was he said he gave it for a core, that one really stumped me I even called them trying to get it back because I don't think anyone actually takes a core on those. I only brought it up in my comment to warn people to just hang onto it for a little bit if they are asked for a core.

My wife and me were walking down a street when we saw 3 or 4 guys pulling out the gas tank from under a pickup truck. They said they were replacing the fuel pump again. He said that was the 3rd brand new fuel pump he has replaced in the past 2 months. I asked him if those new fuel pumps were aftermarket from the local parts store and he said yes. I told him that I've heard aftermarket fuel pump never work very long and it would be better to spent more to buy the OEM fuel pump. That way you will save a lot of time and effort replacing the fuel pump every month.

[@recoveringnewyorker2243]

Back in 2011 when I replaced the 2.2 L engine in my 2000 S10 I also replaced the fuel pump. Very similar procedure to your Envoy. I replaced it with a Carter fuel pump (Made in USA) only to have it leak in a few years. I then replaced it with a Spectra Premium fuel pump (imported, I forget where it was made) only to have the fuel gauge fail in a few years not to mention a persistent check engine light due to a less than perfect vapor seal. I finally “bit the bullet“ and purchased an “original equipment“ AC Delco fuel pump that believe it or not was made in Malaysia. No problems so far.

Worked for a government fleet and had to replace 18 in tank fuel pumps in 6 weeks. A month earlier we had received our winter gas, no ethanol, 3 vehicles, all police units lost 2 pumps each. All were 2014 and newer, Dodge, and Fords. Tanks were cleaned and inspected before installing the new pumps. I noticed the gas was an odd color so I called our supplier, who called the refinery, nothing was ever admitted to be wrong but a few days later the supplier pumped out our 3 in ground tanks and dumped 2,800 gallons in, no charge. No more failures either.

Simply plugging the pipe fittings, degreasing, rinsing with water, then let it dry would have been best, THEN remove the connected hoses on the pump, & remove the pump assembly.

One *very* important thing you didn't address was the recommendation of replacing the fuel filter. Some suggest doing so every 5 years / 50,000 miles and others may say every 20,000 - 30,000 miles. Clogged fuel filters can cause: • Poor Engine Performance (Under heavy or high-speed acceleration, a clogged fuel filter may cause the engine to randomly hesitate, surge or sputter) • Hard Starting • Stalling • Random Misfire or Rough Idle I recently changed the fuel filter on my '93 Grand Cherokee and as I poured the residual fuel out of the filter itself - a *lot* of what looked like black 'silt' came out with it. Definitely was WAY overdue and am now worried there's plenty more where that came from, left in the tank itself. A huge amount of respect to you for tackling this large gas tank... on your back! They're difficult at times, even in a fully-equipped shop with a lift AND a tall transmission jack!

[@spelunkerd]

In about 2001, most manufacturers abandoned in-line fuel filters, instead putting the filter inside the fuel pump assembly inside the tank. Their reasoning was that the filter is better placed in the low pressure side, at the intake for the pump, so that higher pressure line is not obstructed by a filter further downstream. They considered it a safety feature. Check your owners manual for advice regarding how often to change the filter, but many manufacturers abandoned routine filter replacement.

I had no clue what was in the tank so everytime I went out I put $10 in it. When the time came I decided to go in from the top. I measured, remeasured and had my roommate measure where the pump was and decided it was under the L rear seat Soooo, I bought a "low sparking" cutting wheel, took the seat out, cut the carpet and with a sprinkler running under the truck ( go ahead laugh it worked) and my roommate with a fire extinguisher watching under the truck and another friend watching from above I cut a access hole. It took all of 5 min being very careful to just barley cut through the floor. And done. I was right on with my measurements and the pump was right where I cut. Rest of the job took less than 30 minutes. The scary part was I am glad I did not remove the tank. Those $10 stops for gas, the tank was completely full. It actually pushed the ring up and splashed when it broke loose I can't imagine what would have happened if 32 gallons dropped with the tank. Anyway replaced the pump, caulked a huge bead of auto body caulk and put a piece of sheet metal coated both sides with plastic dip on top of that and screwed it in and put the carpet back. Never know I was there. If I had to do again I would cut the floor out again in a heartbeat.

Run a fuel pressure check before and after install of new pump. Low fuel pump pressure from a new pump will reduce idle RPMs but engine computer should detect that and compensate accordingly. I've ran my truck with a lousy new pump with 50% reduced/marginal pressures and can still do +60mph on highway. A good pump should show 40psi at idle, but this will vary based on engine and model of vehicle. China will occasionally have some quality control issues for your car parts.

If you are concerned about gasoline vapors in the vacuum, an air hose would be safer. I don't know how much if any air from inside the vacuum cools the motor but they all have sparking brushes. If you don't have the air hose ready you can use the vacuum as a blower and it works just as good as a leaf blower. The only difference is you don't have to worry about a vacuum full of dangerous fuel vapors.

[@voidisyinyangvoidisyinyang885]

If I leaf blow on top of the fuel tank - to clean off the sending unit - can I spray Sta-Bil Rust Stopper also to prevent rust? Or will that short circuit the electrical connector? Says it's safe for electrical.

Just in case any of you are low on cash, you absolutely can replace the fuel pump or the sending unit sensor on the stock fuel assembly. That simple GM assembly is used in tons and tons of cars including a bunch of enthusiast vehicles. We don't keep the stock fuel pump in there. At a minimum we put in something like a walbro255, or bigger. What this means is after he pops out that fuel pump assembly, you push two little tangs in or undo two clips depending on the exact model you have, And then the inner assembly comes out. You can then remove the stock pump and hose and put on a new pump and hose.

[@vernonlemoignan1392]

I would agree that replacing parts with quality parts is a good idea. However I question the belief that the factory parts are always the best available. If a sending unit is know to often fail at such low mileage, what makes that a good part? I think there are many aftermarket parts just as good or better than the original equipment for less money.. The problem comes when trying to determine if the particular aftermarket part is decent or not. The answer will be different for every part and every aftermarket manufacturer.

I bought a fuel pump with sending unit that came in a box with styrofoam clamshells for my 5.3 Envoy XUV for $29 five years ago. I expected a month out of it as I was told the engine was seized. Bad battery and fuel pump and most definitely a bad "mechanic" yet the lady I bought it from, the car not the pump, continues going to him.

[@farrispatton]

Great video! Also, glad to have it fixed by a handsome mechanic. ♥️

[@jameskennedy673]

At least your fuel tank was almost empty. Years ago the fuel pump went out on my ‘93 Chevy Silverado with a full tank of gas. What caused the pump to go out was a shorted wire where the electric wire goes to the pump, the grommet failed, the wire’s insulation had a whole in it. I was told that wasn’t uncommon on the early nineties GM pickups. Our oldest son had the same problem with his GMC Envoy

I worked for a shop back in Wyoming, And I seen that same thing over and over again! Suburbans lined up in the parking lot with a bad fuel pump and everytime they had 42 gallons of gas in the tank!

Had to replace the fuel sending unit in my wife’s 1999 Tahoe. Didn’t want to drop the tank so I took the rear seat out. Pulled the carpet back and cut an opening in the floor directly over the sending unit in the gas tank. Now I have a trap door so I can easily access the fuel sending unit. They should do this at the factory.

Nice job , I just did a new pump on my 04 Tahoe . Agreed always use genuine parts , don’t want to have to do the job again.

[@Boomer_in_the_Trees]

This is why I love my little Ford Ranger and my old Volvo XC90. Fuel tank for the Rangers right under the bed. 6 bolts, remove the bed and never have to drop the tank. In fact I had a buddy cut a hole in my bed right above the fuel pump so I could easily access it whenever I need to test or replace the fuel pump. And on the XC90 its right under the back seat. Just remove the back seat which is fairly simple, then lift the cover and right there are the round covers for the fuel tank and saddle tank unit. Just unscrew 6 screws, lift off the cover and lift out your fuel pump. Same with the saddle tank unit. My Ranger might be 30 years old and my Volvo 20 years old but they sure are a lot easier to work on than the modern stuff.

When it is on 4 stands it is susceptible to falling down too at and angle like that is SUPER DANGEROUS. Best to put only 1 side in the air if you can and block the wheels on the other.

It helps to try and fill up when you hit half a tank. You never know when you have to make an emergency trip and if you don’t have gas money then you still have half a tank of gas to get you there. Plus it’s easier on your wallet to fill half a tank vs an empty one plus waiting til you’re empty all the time will cause the pump to wear out faster cause the fuel surrounding the pump helps keep it cool. And changing the fuel filter out when it’s due also helps keep the pump from over working itself

I recently replaced the fuel pump in my 98 Taurus SHO project car. I was very concerned about the fumes, but it turned out fine and being quoted $900. from my mechanic was a great incentive. Fuel pump cost $47.00 on line. I'm getting request from neighbors now, to fix their cars.

good job, nice to see the gauge working.

[@davebooth7808]

On my earlier model the delivery hose on the pump actually fell off or dissolved in the tank because the guys doing the job never found it in the tank! So therefore I can only assume that the fuel dissolved it! Another thing is the fuel gauge along with all the other gauges on the dash are all controlled by air coiled motors. Which are sort of expensive to purchase! Unless you buy off a wrecker & get them all for a fraction of the cost like I did!

" Here's Why You NEVER MESS with your factory fuel pump" - Proceeds to mess with Factory Fuel Pump. LOL.

[@rh7163]

This confirms my thoughts on many American built cars which begin with thin sheet metal and far too much plastic, vinyl and smaller vehicles with extremely high price tags. Keep in mind replacing parts like this, on vehicles with less than 50,000 miles doesn't begin to suggest these cars are value for money cars. I have no idea why this fuel pump is so big or why the sender was designed like it is as the old float style provided reliable gas reading while a regular pump was so much smaller and far more reliable but then there wasn't any plastic either. I'm not impressed with this all in one fuel tank module system although I have no doubt they cost 3 times more.

[@e-racer4673]

Take it from a mechanic you should have plugged descending unit in and mechanically moved the leveler up and down to see if your needle moved on your dash before you ever put it all back in that way. If it didn’t, you could have checked your connections and all I’ve only had that happen one time, but it’s a whole lot easier to check all of that with your tank out of the vehicle.

[@joseph78e4n6]

[@jber9569]

If the engineers at GM had half a brain, they would have made the fuel pump accessible through the back seat. I have a Chrysler 200 and all I have to do is pop out the back seat (takes 15 seconds) and, voila, there is the fuel pump. Also, they make fuel ring removal tools that are about the same price as the brass punch set and are a lot easier to use.

[@troy9er]

[@justdanny7252]

Best 2 pieces of advice I can give are: 1. Motorcycle jacks are useful for dropping a tank if you do stuff like this solo. 2. Buy extra seals, they are typically less than 10 bucks and will save you some heartache. Gas vapors/ even a drop of fuel causes the seal to expand. That's why they work so well. If you are going cheap and reusing original housing (just replacing the pump) odds are you may leave 1 drop of gas that falls on that lovely new seal and poof, it inflates; warping and now unusable. 3. If your tank is metal, depending on the age; you may have to replace it as well. Nothing lasts forever. Make your own luck. Plan to fail and watch how others dealt with that failure.

[@voidisyinyangvoidisyinyang885]

can you spray Sta-Bil Rust-stopper on top of the sending unit to prevent rust or would that mess with the seal also? Or electrical? Says it's safe for electrical.

I just changed the one in my Frontier. It was working fine but I blew the fuel line where the steel line connects to the nylon line. I had to drop the tank and it has almost 300k so I figured while the tank was down I might as well change the pump. It would have been a couple hour job if I didn't snap 2 of the strap bolts but other than that it was pretty easy.

[@court2379]

It is ridiculous that we have to spend so much effort to replace wear components and put us in danger of fire when designs exist that avoid all this hassle. This design saves the manufacturer a small amount, but costs the consumer a huge amount for maintenance. That fuel pump assembly for one of my vehicles is $450. The same thing for another vehicle with separate components is $25 for the pump, $16 for the sensor, and $5-10 for the filter. That car with the expensive assembly I have to drop the tank, which means the removal of the drive shaft, and the exhaust because they pass under the tank. To have this job done at a shop would be over $1000, when it could be about $50, or $25 done myself. Having to drop the tank is completely unnecessary with better design. I don't know how we revolt and force better design as it seems many manufacturers are using the same subcontractor's components and leaving us with no alternatives.
