My man you just saved me a lot of pain since my truck is a rust bucket thank you for your video

[@dudewecanfixit]

That’s what these videos are for! Happy we were able to help!

[@digitalcomplexity]

Best video on the fuel pump replacement!! good stuff thank you

[@DStrayCat69]

Great stuff 🙂 I'm using the same #3 method, with a difference... I bought a Marine Floor Access Panel and will install that prior to removing the Fuel Pump in my 2005 Chevy Blazer. Simply cutting a hole in the floor does not close it up when complete. My Floor Panel will allow me to close the hole after changing the pump... Still a great video. Thanks 🙂

[@dudewecanfixit]

That's a fantastic idea!!! Put a link to the panel

[@JesusRamos-zs3zq]

Save me some money Big dog.... Thanks for the dimensions, first time doing it to. But I watched your video about 50 times the night before, changed my fuel pump in a dairy queen parking lot.

[@dudewecanfixit]

That's fantastic! Make a trap door there in case you ever need to access it again

[@JesusRamos-zs3zq]

@@dudewecanfixit I will, your video was a lifesaver literally.

[@dudewecanfixit]

Glad I could help!

[@stevechila6837]

Fuckin a.....I'm bout be doin this soon as my boss gets back n can take me to grab my new pump.....way easier than dropping the tank or pulling the bed.....my trucks a 2000 n fulla rust n I got a bedliner to cover the hole....I may use a hinge tho n make a flip over trap door.....idk

[@jimmason1858]

Thank you a million budd y I got an '02 Chevy Silverado 5.3 extended cab and the dimensions you gave were dead nut center thanks again save me about 12 hours worth of labor

[@dudewecanfixit]

Beyond stoked this was able to help you! We tried our best to not leave anything out so everyone has a fair chance at getting it done. If you ever have a question feel free to ask. We are always down to help if someone hits a snag

[@jamesco0329]

If you don't want to cut a hike in your bed. There are videos that show how to lift the bed on the drivers side. You don't remove the bed completely. A much harder job when doing it by yourself. Save your bed and time cutting. Especially if you don't have the tools. Or risking cutting stuff.

[@dudewecanfixit]

I do explain how to remove the bed in this video also.

[@julio3421]

I like watching your videos but I regret seeing wires that way thats for houses

[@dudewecanfixit]

I have done that same job before with butt splice connectors and have had issues a couple years down the road. You're not going to get a better connection than wire nuts unless you solder. I zip tie and wrap all my connections and have NEVER had a single issue this way. Just trying to help people not have to go back and replace faulty splices. What would you prefer?

[@julio3421]

I prefer solder I love your videos but prefer seeing u do better solder is the way to go

[@dudewecanfixit]

Solder is nice, I prefer it also. This channel is aimed at everyday DIYers and most people don't have soldering equipment or knowledge to do it properly. If it is done incorrectly it is brittle and can break causing a bad connection. I have seen it happen in lab classes in college, I have a background in electrical engineering at LSU. Anyway, even in automotive applications, wire nuts are the all around easiest, most available, and reliable connector on the market. I have used them in my personal vehicles and my dump truck with zero problems. I always wrap them with electrical tape to keep water out and zip tie to keep tension off the connector. Wire nuts are also handy if you need to change a connector out in the future (as I did in this video), cant do that with solder. Prove me wrong and I will gladly change my ways. I appreciate the comment and criticism, please feel free to express any concerns as we all learn together.

[@carylamari6546]

As an electrician I wouldn't trust wire nuts outdoor on stranded wires. It will work but the chances for failure are huge. Wire nuts oxidize and will come apart. they aren't approved for outdoor use especially on a fuel pump. A crimp cap would be my choice other than soldering but soldering with shrink tube is the best method. Other than that the video was great.

[@carylamari6546]

If you do want to trust wire nuts I suggest using silicon around the connection, this will deter some oxidation and potential rust of the spring but it is not the approved method.

[@lukeedison1632]

Dude this is fantastic work - thanks!

[@dudewecanfixit]

Glad you like it!

[@dudewecanfixitshorts]

Beautiful video fellas!

[@dudewecanfixit]

Thanks! You're beautiful

[@JohnSmith-xx1lx]

I was going to say a good idea would to be get an air compressor or blower out and blow off all the rust after you've broken the ring loose from the fuel pump so the settlement doesn't fall into the tank.

[@dudewecanfixit]

That’s a damn good idea! We’ll keep that in mind next time

[@FoUoCoKYOUTUBE]

Buy a welders small fire blanket, wet it, place on fuel pump and cut away.

[@dudewecanfixit]

Great Advice!

[@coolpeanuts23]

Always look forward to you guys posting!

[@dudewecanfixit]

We appreciate it more than you know!

[@Jabs420]

Could i even lift the box if i have 5th wheel brackets/rails?

[@dudewecanfixit]

That's a great question! Sadly, I don't know

[@prmayner]

Cutting the bed is the only way to do this job so easy and quick and without running the risk of breaking those plastic fuel lines. One note the purple wire is fuel gauge sending unit, the gray wire is fuel pump 12v and if you look closely there are two different size black wires, the bigger one is fuel pump ground wire and the smaller one is unit ground. I did mine in about 30 minutes including cutting the hole. 1991 silverado ext. cab short bed.

[@dudewecanfixit]

It is in fact very quick and easy! Removing the bed doesn't take very long if you have someone to help pick it up.

[@MinnesotaisRust]

This is not an easy job, thanks for sharing!

[@dudewecanfixit]

Happy you enjoyed!!

[@not1tosettle]

Hey in what way did you close up the hole in the bed? Thanks

[@dudewecanfixit]

I didn't do anything. You could weld some hinges on there and have a quick access panel

[@josephnovak4826]

great video me i would solder wires and heat shrink with tubing.......

[@dudewecanfixit]

Great idea

[@michaelpipkins2559]

Will these measurements work for on a2001 gmc extend cab 4 wheel drive z71

[@dudewecanfixit]

They should, but you can always double check with a tape measure before you cut

[@michaelpipkins2559]

@@dudewecanfixit most definitely

[@shanefuller8880]

I know this video is a few years old, but my question is, would the measurements be the same on a regular cab with an 8ft box?

[@dudewecanfixit]

You can verify the measurements with a tape measure from underneath the bed

[@ZIGZAGBureauofInvestigation]

Question ? Could the size of your cut on the bed, a little smaller. If you were to do it over, how big of a square cut would make. Great work ! Thanks.

[@dudewecanfixit]

I like the size because it gives me plenty of room to work. It could probably be smaller but I don't have the truck to get dimensions.

[@ZIGZAGBureauofInvestigation]

@@dudewecanfixit thank u

[@dudewecanfixit]

You're welcome

[@PdxGxs]

Should have vacuumed area before removing fuel pump.

[@dudewecanfixit]

Good idea

[@jeffbensoutdoors1623]

Awesome video but you didn’t show how to replace that big hole in the bed cannot weld it over the tank?

[@dudewecanfixit]

You can weld over it for sure. It’s a project truck for us so we don’t really care about the hole lol

[@thecolorsofmyshade5603]

Why is no one putting a hinge and latch on it? Seems to me it would be a quick easy solution for the future

[@dudewecanfixit]

That would be the absolute best thing to do!

[@thecolorsofmyshade5603]

@@dudewecanfixit oh 🆒! Can you give me pointers on fixing my '03 z71 fuel pump?? My tank is 3/4 full and I have no jack or stands to drop the tank...I want to go through the floor behind my seat but don't know how good I could seal the panel with a hinge and latch IF I get it done..... I'm stranded until I get it done and I'm jus a chick without tools.. thanks!

[@dudewecanfixit]

Don't go through the floor, the fuel tank is under the bed unless you have an SUV. Best bet is to take the bolts out of the bed and then prop it up on the driver side with some lumber while you work on the pump.

[@Mookie21378]

Man those East Coast vehicles are rust buckets 😮...

[@dudewecanfixit]

Big time!

[@adamgalloway6539]

To me cutting a hole allows for water to get in and cause more rust issues , my bed has a spray lining in it which I hear makes a mess when cutting the hole , guess I could silicone around it after lol

[@dudewecanfixit]

You could also remove the bed. I show the bolt locations and electrical connector to remove the bed. If you have a couple extra hands, it's pretty easy

[@dgrossi8471]

Do you know if your measurements work for a 2007 GMC Sierra 2500 HD Crew Cab?

[@dudewecanfixit]

I am not certain, that is a newer body style

[@J.G.M.-cm5bq]

Do these dimensions for cut out match up with 2000 GMC 1500 4wd 4.8L with standard cab?

[@dudewecanfixit]

I am not 100% sure. You can look underneath the bed and pull some measurements to see

[@rogerracicot8804]

what about the fire risk for using a disk grinder to cut the hole causing sparks over a gas tank ???

[@dudewecanfixit]

Caution must be used around the fuel tank. It's a sealed system. Don't cut the tank and fuel lines.

[@kylermitchell9384]

Would a 94 dually be same measurements for the hole

[@dudewecanfixit]

You can look under the bed and pull some measurements to see if it's the same

[@jeffro221]

Can you tell what year model, cab style, and bed length GM truck this was done on, if you can remember? (short 69", standard 78", or long 96")

2001 GMC extended cab with standard bed

[@antnope3042]

Do you have to plug them both and even with the new connection?

[@dudewecanfixit]

You don't want to get any contamination in there

[@dustinseely5826]

We have a 1991 chevy Silverado and we want to cut a hole in the bed to change the fuel pump ?

I'm not sure what the question is. You can take the bed off the truck to gain access. I show all the bolt locations to remove the bed.

[@savagesock3598]

Someone already cut out a hole and put a plate on it, looks like I've already worked on it. 😂

Will these measurements be compatible with a 2002 chevy silverado with the 4.3L?

@@dudewecanfixit thanks again for response. Starts fine cold, never has and power issues like stalling or sputtering. Only after engine is hot and has been shut off for a short while, I get an extended start will sputtering.

[@jakobjoy4193]

Do these dimensions work for a 1994 Chevy C1500 Z71 extended cab?

It should but you’ll just have to locate the pump from under and make sure the measurements line up properly.

I got a 94 s10 tomorrow i gotta replace the fuel pump in it do you know if the dimensions that you gave for that truck will work and also what did you do to put the plate you cut out back in

[@dudewecanfixit]

I don't think the dimensions are going to be the same unfortunately. You will need to figure out where to cut the access hole. I didn't put the panel back, however, I would recommend welding a couple heavy duty hinges to make it convenient for next time.

[@pillowbugg]

Just tilt the bed instead of cutting out a hole

[@dudewecanfixit]

Do what you do, I normally move the bed back a couple feet and set it on the rear tires. This truck is just a special case, lol

1ft and 25-1/2 inches lol

Just drop the tank. Wtf

Perhaps you should rewatch the beginning of the video, I explained how to access the fuel pump without cutting the bed and I explained why I did it that way.
