Dealer Offers Me New Fuel Pump for Study?

The 89 GMC I owned previously, and my current 94 S-10 had the fuel pump go around 120,000 miles. These are the only two vehicles I have replaced fuel pumps on ( the lowest milage vechile I ever got rid off was around

160,000. > Some time back I brought my 98 GMC Suburban to the Dealer for a recall

I have a 97 S-10 Blazer, 4.3, A/C, Auto, manual stuff, cloth seats, 2 door, 2wd. The fuel pump failed at 104,000. $800 plus I had the fuel filter, and a few other things done, it was about $1,000 all said.

A friend has a suburban (2002 I think) and is on his 3rd pump, don't know the mileage but not much over 100k.

I've asked, and it is likely urban legend.. fuel going through the pump cools it. But since it is immersed in the gas, I now fill at 1/2 tank, or in my case, put in 11 gallons, and don't let it get below that level. Previously, my routine was to fill such that it took 14 gallons (of 21). Don't know if this helps, but can't hurt, other than the inconvenience of filling up more often.

I sure would like to learn more of this "study"!

Chevy had problems with some fuel pumps on different model trucks. The problem was not so much the pump it self as it was the ground wire on the outside of the pump would corrode and go bad. My brother had the same problem with corrosion on his 1997 GMC pickup 1500. I not sure of his milage at the time but I do know it was a long tow with my truck to get him from out the woods. Not to mention we had to unload a cord of fire wood before pulling him.

I changed mine at about 128,000 miles when my truck was stalling out. I found out after removing the bed that the pump was not the problem that the ignition switch was bad. I changed it anyway since I had the bed of the truck lifted to do the job. Lifting the bed was easier then lowering the tank, especially when you have a full tank of gas. I have a 2000 C2500 Chevy truck.

1997 Gmc Sierra 5.7 First pump bad at about 85k Second pump 140k Rod Bearing 144k New Crate motor from GM in now 145k

My 87 S-10 Blazer had the fuel pump fail at 250k miles, the 91 I have still has the original at 247k, but I believe its getting ready to fail. As I think about some of the posts here, the 87 went bad when I gave it to my daughter to use, and I am sure she was not one to keep the tank full. The 91 I usually don't let go below 1/2 tank in normal driving. On the highway, I start looking around 1/4 tank for a fill up, the last year of driving had a lot of highway, as I put 43k on it.. Would be interesting to see if there is a correlation between running the tank low often and rate of pump failure.

I have a 89 burb with 172k on it and still he same pump ans it still sounds the same too best I can tell. I have a "theory" on GM tank mounted fuel pumps and their lifespans. The pump is designed to be cooled and lubed by the fuel in the tank so if you run it low a lot it stands to reason that you may have shorter pump life. The only time my tank ever gets low it on a trip before refill, otherwise I rarely let it get below 1/2 tank.
