    I think mine just shit the bed.. 99 4.3 2wd. Had it replaced a year ago with 104 on the clock to fix the sending unit. I drove it home last night from the gym, was low on fuel, parked overnight. Came out the next morning and its a no start. Dumped some fuel down the TB just now and it fired right up.

    now here's the kicker, I called a buddy of mine who knows S10s like the back of his hand and he said that the pumps were designed so that anything under half tank of fuel, the pump would overheat and burn up. This sounds like a load of BS, but I was wondering if any of you guys heard that too



    gunna go smack the tank with a big hammer to see if that works

  3. Can you hear it buzzing when you turn the key on?

    My brother had a 96 S10 and the fuel pump died. We replaced it ourselves in a few hours. If you want to do it yourself you are lucky you don't have much fuel in the tank.

    You friend is right but he made it sound like a scam. Its simple physics that makes the pump work harder the emptier a tank gets. I always fill up my vehicles at a 1/4 tank.

    For the amount of pressure a fuel pump like that generates and extra 6 inches or a foot of rise is nothing. Some of them are designed to use the fuel to cool the pump though, so running low on fuel does heat the pump up more.

    I had this problem running a Walbro 255lph pump in my truck: once the level of fuel cut off whats in the bucket from the rest of the gas tank it would get hot and shut off. Sounds like you were running a higher flowing pump.
