stock fuel pump problem my stock fuel pump was replaced a few times already. Now it had gone out again.
they showed me the inside of the fuel pump and the plastic hose inside was melted. now they can't figure out what's causing it.
any ideas?

Do you by any chance run out of gas quite a bit ? Sounds to me like the inside of your pumps is overheating at times , and causing the internals to melt . This is a known problem if you run out of gas , because the gas lubricates the pump and keeps it cool .

khshapiro - the fuel i use is 91 octane. I use this fuel all the time. all the parts are gm certified parts. the fump is by gm, and the plastic hose inside the pump is built-in.
mike - the car has 15k miles on it. the car did run low on gas a few times to the point where the check gauges light would come on but not a whole lot. and it's been a while since the last one. You mentioned something about the gas keeping it cool and lubricating it. on all the times the pump went out, there was over 1/4th of the tank with gas though.
what else can cause the hose inside the pump to melt?
the mechanic thinks I used racing fuel but I didn't. They had the fuel sent to a lab but nothing showed up.
the problem occured when I removed a supercharger that used a Fuel Management System. I'm thinking this might have something to do with it. But the mechanics checked everything out and they say it's fine. ANy ideas?

it seems like the pump is going out after the car is turned off and after it cools down for a while. after the car turns off, is there some kind of a cooling device near the fuel pump? or something to cool the fuel tannk?
Does a radiator have anything to do with it? I changed my radiator to an aftermarket.
