Fuel pump replacement time

[Tamcphail89]

hey guys, it's time to replace the fuel pump on my 04 Escalade. Would you all just go with the factory replacement AC Delco or is there a better option?

Thank you

And 4.5 hours. Look on eBay for good price or rock auto.

factory factory factory.

As far as how long it takes, it honestly really depends. Empty tank and no rust? An hour, if that. Rusty and full tank? Bit longer. If you know you're rusty, pickup new straps and fuel pump retainer if the new one doesn't come with it. Can't remember which years have plastic and which ones have metal lines. If you're in the salt belt, plan on replacing fuel lines too

Don't forget the fuel line disconnect tools. You'll have a good time trying to get them off without them

I went with AC Delco.

Looking on rockauto, there's 2 ACdelco pumps.

As @SnowDrifter says, new straps are a must, and be prepared for new lines depending on mileage / location. Those babies can snap easy, just lube them up some before trying to remove.

I got the $150 rockauto fuel pump and just installed it this past weekend. If you are in an area that gets rust, I'd recommend picking up the fuel line connectors with the repair line kit that comes with the new connector attached to a new fuel line section. With a 1/4 tank of gas left in the tank it wasn't too heavy. Took about 6 hours total to do and had to deal with some difficult connectors on the other connections.

One says for base model, one says for ESV and EXT models.

That shouldn't matter as long as it's for the correct year and motor? Right?

The ESVs have different tanks

It must matter or there would only be one part. Of course, if you’d rather order the one for a different model than yours and wait until your tank is out before finding out if it works or not go ahead. Not trying to sound like an ass but there is no reason to order the wrong part for your rig when it’s basically the same price. If a part is listed as application specific, there’s always a reason. No use taking chances.

Oh OK, I was unaware of the different size tanks.

Thank you

Ok so i'm gonna get the fuel pump, tank straps, and the lock ring. Is there a filter inside the tank that i should replace as well? Trying to make sure i get everything i need.

Thanks.

The filter is part of the pump assembly. The clip nuts for the straps are what broke on mine when I did it. I found them locally. Also I bought a package of dorman assorted fuel line clips for the quick connects. As someone else mentioned, they can get a little gnarly when you're trying to get them off. I also put a good coat of bedliner on the metal head of the pump to try and keep it from rusting.

This is unconventional as hell, but for rust, see if you can find some roofing tar. The stuff is an absolute godsend for difficult areas that need to last for a long time without reapplication. It is a bit of a dirt magnet though, so think before you go nuts and do up your whole undercarriage

Just tape off your connectors before applying

New straps are a good thing to order when doing the job, I just replaced my fuel pump a few months ago and a month afterward i pulled out of work and heard a horrible noise from under my yukon. The rear strap broke while i was working and it was hitting the U joint. I climbed under and pulled it out. Luckily i made it home without a problem. After looking around at aftermarket straps i decided to go with OE GM straps.

Helped a buddy do his barn door GMC fuel pump. He used a local part house special. It was dead in a year. It was a Cali truck so straps were ok. Time consuming if it’s your 1st go at it and you deff want an empty tank.

Use the oe pump or you’ll be doing it 2x. Don’t use a pump that your trucks not spec’d for. The tanks ARE different by volume and especially height. You don’t want a fuel float designed for a higher/lower tank or one that can flop around because it’s too short to press on the bottom of the tank.
