Replacing Fuel Pump Without Dropping the Tank. Fuel pump replacement in 3rd gen Fbody.

[@zztop8592]

The old fuel pumps on the engine were best! LOL

[@outdoorswithcam]

Sure were a lot easy to get to. Two bolts... But they never quit because were mecanical... Thanks for the comment. it really helps the chanel

[@robwagner7559]

And those won't adequately pressurize a fuel injector rail. They are ok for fuel wasting carburators

[@MultiRokusho]

Things like this is why I’m glad my sc 300 can be accessed just by unclipping the trunk carpet.

[@outdoorswithcam]

Yup. Why don't they put a hatch there? I did a Durango and you had to drop the tank. I looked into cutting the floor out also but one of the mounts for seat was directly over the tank. Thanks for the comment

[@gstempeck]

Years ago I did this on an 85 Camaro although I never cut the lines. I just pulled the fuel pump out lines-included and replaced it and put it all back, was that not an option here? Cutting lines sure seemed to make this a much more challenging job. Appreciate you for sharing the approach and tool you used - I had used a Dremel tool to cut and sent sparks everywhere, do not recommend.

[@outdoorswithcam]

Thats for the comment. The fuel lines are bolted to the frame in two places. I saw no way to pull the pump without cutting line. The bolt hold the lines was underneath on from. Only one line has pressure. Modern day stuff all have quick connects on the lines. I have replaced this fuel pump twice before and dropped the tank. As I said in the video I think its the alcohol in the gas eating the pump up. When this car was made they didn't put alcohol in the gas.

[@bobreese4807]

So..2 years ago, I asked a mechanic to replace my 1998 Dodge Caravan 2.4L fuel filter that was changed 22 years ago. When he did it he cracked the fuel pump connectors and it leaked gas. I paid for the part and he did labor free. Bosch. The gauge read low. Still had 5 gallons left when gauge was at E. He replaced it and same level issue. I said forget it and was same for 2 years and 2 months. The sensor started making the fuel gauge needle go down and the chime came on with the gas tank idiot light coming on. I GOOGLED it and saw complaints like this and saw might be caused by sulfur in gas tarnishing the metal on the sensor metal.. I put in 2 bottles of Techron plus and for a time chime was lot less but now is awful!. So far I can't find what metal the sensor windings are made of for BOSCH. I see 2 brands, one using gold (Delphi) and other silver palladium. THEN... I see ranges of 70 to 1050 OHMS for replacement pumps (ON Rock Auto info on their pump assortments. and then I see 33 to 240 for Bosch and American makes. I was about to put a cheat resistor in the harness to make it so I could stop the low level CHIME stop. BUT now I don't know what value to put in. I was going to put in a 680 or 750 OHM but when I saw this new range. I put a temp hold on this cheat. The gauge anti- slosh makes the needle move slower but the chime comes on right away. I think the float needle is getting to a dead high OHM spot on the sensor. I found out a couple weeks ago that Bosch went to a lifetime warranty.. but there are qualifiers and so I will see what push back I get from Bosch.

[@outdoorswithcam]

WOW sorry you are having all these problems. I thought the sulfer on gauge was a GM problem. Never hurt of it on Dodge. But what do I know...

[@bobreese4807]

@@outdoorswithcam When I called Bosch tech support yesterday (about fuel pump), I asked him what metal the sensor windings were made of. He had no data for answer. He didn't have the OHMS range of the sensor either. The range is usually about 30-1050 OHMS on other after market pumps. ..and shows on Rock Auto spec lists. Dephi has gold compound, another after market has silver palladium.. One uses brass. My original pump lasted 26 years, 160k miles and no gauge problem. Now I am trying to find details so I don't have problems with pumps like this one that has a problem just 2 years later. One can see multi complaints on the fuel level sensors on the internet. And..I have been using Costco top tier gas. Interesting, Maybe a coincidence, but this problem happened right after I put in Costco premium. Also , I recently put in BG 44k too. For a long time, my MPG was at 15-17 on street instead of 20. The mechanic told me carbon deposits, so I have been trying to clean out with Techron. For 26 year old van the mileage is low, now 172K. The transmission is rebuilt 2nd time. Had it recently painted The vehicle is only used about 5k miles a year. Not ready to junk it at all.

[@bobreese4807]

@@outdoorswithcam Since I have been an electronic tech for 50 years..I plan on doing a modification to the sensor wiring to shut the chime off. I am installing a 750 or 820 OHM resistor across the sensor wires that are in the harness that attaches to the fuel pump. That will make the computer think that there is at least 1/4 tank at all times even when the sensor float rod hit an open circuit point on the sensor metal windings. When there is a connection of the float rod, the gauge will read higher but I use the miles trip feature to check the gas remaining. Since I have had the Bosch, it didn't read correctly anyway. Too bad I didn't know about transferring float & rod of original to the new pump.

[@outdoorswithcam]

@@bobreese4807 Where to buy resistors in todays world? I used to do all kinds of mods. When I used to drag race my trans ams. I would go out and measure the OHM of the IAT sensor when it was a 30 degrees outside. Then I would go to radio Shack and buy a resistor with same value. Then when it was summer and I was raceing. I would pull the plug off sensor and stick resistor the into the plug. So basically telling computer its 30 degrees when it really 90 out. So it would dump the fuel. If I was raceing an identical car I would beat them with that trip. I have bypassed alarm systems with resistors... But where can you go today and find drawers with different resistors like in the radio shack days?

[@locotrucker46]

You showed which two lines were pressure line and return line what were the other two lines?

[@outdoorswithcam]

One is high pressure from fuel pump. One is return from fuel regulator. One is chargo canister. Fourth is vent that goes to check value in front of left rear tire.

[@Tyyyyuru]

Does the 3800 get vapor lock? She dies when she get up to temperature.

[@outdoorswithcam]

That sounds like a closed loop issue. I would be look at a sensor failure. Fuel injected cars don't vapor lock. Vapor lock was issue with metal fuel lines and carburetors. Carbed car had manual fuel pumps at what 8-10 pounds. Fuel injected car should have 40-60 pounds with half the fuel bypassing and going back to tank cooling everything. Failing fuel pumps will die with heat or high temps but thats not "vapor lock".

[@Tyyyyuru]

@@outdoorswithcam as a matter of fact I am throwing an O2 sensor. Is that closed loop related?

[@outdoorswithcam]

@@Tyyyyuru open loop is before the ECM kicks in and controls everything. Open loop everything is preset based on temperature. Once engine warms up ECM(computer) kicks into closed loop reading all the sensors. O2 sensor controls everything. It should be going back and further between rich and lean. Yes thats what an O2 sensor does. It measures how rich/lean the mixture is. The ECM is constantly trying to lean the engine out for MPG. Find that balance. ECM looks at O2, throdle position, MAF(air flow) and RPM. It makes a spark curve and a knock chart. This is all viewable on your Laptop or scantool. Useing the O2 it leans the engine out till it knocks. Forms the knocks table. So it knows how long to hold the injectors open to try and maintain and air/fuel mixture of 14 to 1. Yes O2 sensor can screw stuff up real fast. BUT O2 sensor lean is one of the most common codes. If you just pull DTC codes and it says O2 lean. people replace but most times that is not the problem. Dealers all the time pull O2 sensors out and just burn the carbon off them and put back.

Would this work on a 1995?

[@outdoorswithcam]

Possible. I know lots of people do this even in pickup trucks. It is so easy to just cut a hole esealliy when tank is full

[@yallainrite3658]

What happens if the high pressure or return hose fails while driving down the road with your kids in the back seat?

[@outdoorswithcam]

If the line falls off the car quits running and fuel pump stops. The lines are not going to come off. I put the cut out back in. Then the padding and carpet. I am not driving down the road with a hole in the hatch. I would be more concerned about CO poisoning than a fuel leak. Then you would have the noise and heat coming in.

[@filmart430]

Nothing because even though those cars have back seats, no one fits back there.

[@dangeary2134]

Compression fittings generally don’t fail like that. Also, a lot of those early F bodies had the fuel pump at the engine, they were still mechanical. The pressures were not as high as cars today, either.

[@CS-oe8og]

That’s why it’s considered hackery, among real car people. Easy isn’t always right. In the last 5 years I’ve had my tank out of my 92 three times now because of bad pumps, or a bad sender. It doesn’t help that it never gets driven, but I guarantee you I’m not cutting my 1LE up. They fetch much more money when not butchered.

Did you ask for a AC Delco pump at AutoZone or did you do like everyone else and just buy the cheapest

[@outdoorswithcam]

Thanks for the comment. I don't buy cheap generic parts for something like this. BUt maybe I should. As I show in the video I replaced with a A/C delco pump from Oralies. But when I get it out of the box it shows a manufacture date in the 90s. So I guess its new old stock. When I pulled the old one out you can see the sleeve is all ate up by my guess ethanol. We didn't have 10% in our fuel back in the 90s or when this car was engineered. Now thats all you can get around here. You can't even buy REC fuel here. I could go to the airport and buy 100LL lead gas I guess.

[@4speedpony]

I would've at least "Flared" both ends of the fuel pressure tubing just for conscience's sake ;-)

[@outdoorswithcam]

Perfect world yes you are correct. My goal was to get car moved. It was parked in yard. To hard to jack up on grass or crawl under it.

[@Christ-1]

I used a line compression fitting for my high pressure line. Your fuel pump should only be putting out 42 psi, so why wouldn't standard 50psi fuel hose work??? You shouldn't need that expensive fuel injector fuel hose with that pump. I removed my pulsulator. Seems like an unnecessary variable in the equation. Good work.

[@outdoorswithcam]

Thanks for the comment. I used High pressure for the one line. You are correct 42 max. Rest were line rated for 10PSI. Recently i was re plumbing a 66 buik. I went to Autozone, Oraieley, Advance. The only thing any of them carried was high pressure hose. My only option to acquire low pressure hose was rural king. So 30 minute drive one way. Time is money. Take an hour drive to get low pressure hose when three parts stores are within couple miles but NONE carry low pressure(carb) hose any more.

As a Paintless dent repair business owner, take it to a professional. I typically end up charging customers 2X to fix the damage they tried to repair. It only makes it worse

This fuel pump goes out every 5 years or so. The first time I did it "professionaly" with aid of a "real". mechanic. This time I just cut a hole. Riveted plate back and put carpet back. SO much easier. And in 5 years when it goes out again it will be so simple. I think its the ethanol in the gas eating them up.

Why not just jack up the car and drop the tank. Total hack job

[@outdoorswithcam]

Have you ever done that on 3rd gen??? I have done it twice and will never do it again. I own several of them. First you have to have a lift. It's impossible to do just jacking up. It took me and anouther guy 2 days to do with lift car 6 feet in air. First you have to drop exhaust pipes from cat all the way back. Then the sway bar and suspension has to come off. Then you have to support the full tank on transmission jack. Problem is angle of filler neck. You have to bend it to get it out. Then bend back on reinstall. Remember full of gas. If I am not filming it. I can cut hole in top replace everything and be done under 2 hours. Tell me how long it takes you replace jacking it in drive way without lift? Maybe your doesn't have duel exhaust pipes and suspension parts under it. Please tell me how you did yours?

[@JamesHemme-rg1rk]

@@outdoorswithcam I did mine in 2.5 hours. With large jack stands. No lift. If I had a lift it would be out in a hour. Just has the I pipe over axle.

@@JamesHemme-rg1rk WOW you are one great mechanic! Mitchell1 estimator says it takes 4.8 hours. If you can beat the rate manual by 1/2 you are good.

Don't even need a ratchet or wrench. Wife Jag has a tank access hatch under rear seat.
