Since i bought my truck the fuel pump seems to whine quite loud every once and a while. It also seems to affect the starting after sitting for a while. The fuel doesnt travel fast enough for it to turn right over so it cranks a bit.

I asked my mechanic and he said he has serviced many 4r's where they just change the filter and the fuel pump ends up being fine, the clogged filters end up making the pump work harder and in turn make it whine.

Im hoping in my case he is right, i looked at my filter yesterday and boy oh boy is it rusted ...i am almost positive the nuts holding it on will snap along with the lines.

Any suggestions ?
