View Full Version : 1998 Chev Silverado Fuel Pump Cost
10-04-2009, 09:21 PM
Just inquiring to see about how much it will run me to get the fuel pump replaced... The pump itself looks fairly cheap but I think it's a bugger to do...I also have to replace a broken sway bar link and might as well do plugs and wires as they may never have been done on this truck. It currently has 166K on it...Also do I have to replace both sway bar links or can I just replace one..
Thanks and think snow.

I just had to replace the fuel pump and one sway bar link assembly on my 1998 gmc suburban. Yes you can replace one but they are only $9.00 each at advance auto parts for the OEM replacement so might just as well do both, I did.
The fuel pump is not that bad but you will need a special fuel line disconnect tool for the fuel lines. Make sure that you get the tank as empty as possible and try to get another set of hands to help drop the tank. Make sure you do not rip out the wiring harness as these are not usually long enough to drop the tank to the ground. I cannot reach mine on the suburban without dropping the tank a foot or so, I don't know about a pickup.
Once the tank is off blow the area around the fuel pump lock ring with some compressed air to clear the loose dirt and debris.
Putting it all back is just the reverse, make sure you connect everything back up including the vent hose and filler hose (I know from experience, don't ask). Good luck and allow a few hours if you have help. My pump cost about $250.00 form advance auto.

If like the 99 Blazer the FP is electric & in the fuel tank & is at least $200. Not sure where the fuel tank is loacted on the truck. Typical replacement problem with Blazers.

It may be easier to take the truck bed off instead of pulling the tank, that is how I usually do them. Most of the time the box bolts are easy to get out, unplug the taillights, take the screws out of the fuel filler by the gas cap and then lift the box. It only has to go back a little way just to get at the pump. Or you could cut a hole in the bottom of the box and then put a bedliner in it.

Oh my gosh!!! take the box off is easier????? not. 2 straps and the tank drops down. Do not reuse the gas in the tank (unless it goes into your K MART lawn mower) pump runs around $200 bucks with pickup, pump and all. just did our 98 3/4ton 350 . work truck and our 98 3/4 ton suburban 454. Dealer said they went because we changed the fuel filters and the pumps were used to the back pressure from partually plugged filters. The pumps went within 200 miles of the filter changes. Note: both trucks had over 200,000 miles with the original filters. bad me.

Don't laugh...I pulled the rear seat out of my daughter's ford tempo that had 4 wheel drive and cut a hole in the body to access the fuel pump which I purchased from the suburban ford dealer for $150...and they thought I was going to pay $900 to drop the rear axle and springs and tank...taped the hole shut with duct tape and told my daughter to stop being lazy and put the fuel cap on no matter how cold it was.
Did my buick a couple years ago, and they actually had brains enough to put an inspection port in the trunk, taking that job 3/4 hour instead of the usual 4-5 hours...or in booondocker time...all day long.
you may need new j nuts and strap bolts you need 3" bolts with threads the whole way

Did one on my car a few years ago, I just cut a hole in the trunk pan to access and change it. Yeah, I know it's only a couple straps. They were rusted, the tank was rusted, I didn't want to disturb anymore than I had to.
Word of warning, Do not buy cheap made in china fuel pumps, 90% chance it will fail with in 6 months. Bite the bullet and buy an AC Delco, NOTE-Much cheaper from AC Delco dealer than from GM dealer. I have several customers that are in the auto repair business and they will not install one of these pumps because of customer dissatisfaction. They had to many come backs because of these cheap pumps.
Just about every fuel pump sold by auto parts stores will be made in china, not matter what the brand name on the box. I personally know some who replaced 2 new pumps in a matter of months and finally the 3rd time with AC Delco. No more problems.

I too pulled the bed off. by doing it this way I did not have to break lines loose there is enough slack you pull hole unit out replace pump and reverse procedure you don;t even have to remove fuel. now that was on my 1994 GMC not sure how much difference in 4 years good luck how ever you do it pretty common problem with those

I just did a fuel pump on my 2002 GMC Yukon with 170,000 miles. Go with the G.M. pump. It will be a drop in assembly including new gasket. With the age of yours you might consider getting the lock ring for the top of the tank that holds in the pump as it could be rusty and thin. You just dont know until you pull it. Some pick-up owners without access to a hoist do remove the bed to avoid working low and all the other pitfalls of dropping the tank. Coach & motor has good pricing if you dont have an A/C delco supplier in mind. http://coachmotor.com/

I would be willing to bet a small amount of cash that removing the box is easier. If I remember right the fuel pump and sending unit is an assembly, it's long and fragile. I would not recommend trying to pull it out with the tank lowered without seeing it very well. I disconnected the tail-lights, pulled I think 8 bolts, had a buddy and I lift the box and slide it back a few feet, don't need to set it aside. After that you can access it easily and carefully, replace frayed hose or what have ya. Plan on a few hr job and it really is simple to do. Everybody will tell you to replace the sending unit while you are there but wait till you see the price of that, plus if it ain't broke , why bother

I worked at dealer for years and thats how they do it--take box off just tip up one side.
with that said I did my pump A year ago and i pulled it in the shop DROPED THE GAS TANK but the straps and the bolts all came right out easy as pie..

I pulled the bed off my dodge ram and a chevy to change the pump. I found it to be much easier than dropping the tank and a little easier to replace the pump. I had the dodge done in about two hours.Had to do it in the drive way were it died.

These guys are right about buying the good pumps. Definately go with Delco or you will probably regret it. Just did the fuel pump on my work cruiser 98 Olds Bravada. I attempted it myself and was struggling a bit. My buddy is a mechanic and our wives were talking on the phone probably laughing at me and he heard I was working on the pump, so he came over and told me to get out of the way. I gracefully did and grabbed a beer. My buddy had the tank out in 15 minutes and the new pump and tank back in within 45 minutes. I couldn't believe it. It is an easy job if you know what you are doing and have all the specialized tools. My pump came as an assembly with the pressure regulator. The cost for it was $389. Hopefully yours is cheaper.

Thanks for all the help guys... I will get it set this weekend... I will most likely take the box off as it is in suprisingly (no rust) good shape on the underside...
I'll keep ya posted..

m8man, I'm anxious to hear what you ended up doing and how it worked out. My 2000 Silverado needs a new pump (i think) and I will hopefully be tackling this before winter sets in. I'm hoping I might get lucky and it might just be the filter. Only problem is the stupid filter is corroded and I'm kinking the lines trying to get it off.....

I would not recommend to do it this way. But I have tell you guys how a guy I know replaced his fuel pump. He cut a hole in his box to access the pump. When he was done he covered the hole back up with a piece of plywood.

The truck started working just fine two days ago.. I did let it sit and not touch it for a couple of days and wa la it started right up.. I've been using it to the tune of about 250 miles and 25 or so starts since it started working..I plan on plugs, wires, fuel filter..I've also noticed now my tailights went out and when I open the drivers door the radio cuts out and the lights do not go on until the door is fully open... I have to check this out as there may be a ground issue SOMEWHERE.

Airtex Master / Fuel Pump
2 connector Complete fuel pump module assembly and strainer. Wiring harness included in the box. Drop fuel tank and clean before replacing fuel pump. With module code GAL, GAP, GAV.
Hardest part is pressing the pump back in the tank. I did mine 98 gmc in 2 hours.
for about that same price I can buy a AC Delco pump.
Note-Per the AC Delco lookup, 4 possible different fuel pumps used due to emission system in use on vehicle.
