Rusty Fuel Pump
After 4 years of not using my front fuel tank because it would leak fuel, I decided to replace it. (Truck is a 93 F150 XLT extended cab with 5.0 and duel fuel tanks)
The day before I replaced it, I flipped the switch to the front fuel tank to see if it had any fuel left. The fuel gauge needle went paste the Full line, the truck sputtered and died as if it wasn't getting any fuel.
Today I replaced the rusty fuel tank, inside I found a little fuel left inside, but it was orange from all the rust. I am concerned that the old fuel pump may need replacing. Correct me if I am wrong here, but I should replace it because it has been sitting there for 4 years, it has been sucking up rusty fuel.
What do you guys think?

You should probably replace it while you're in there, just to avoid having to go back and do it all over again.
But don't buy a cheap pump - if it's not high quality you might as well leave the old one in.
You're going to have to run some seafoam engine treatment (in your gas) through your fuel system. And change your filter.
Last thing you want to do is plug up your injectors.

I wouldn't use the pump if it's been in rusty gas. I also wouldn't use it because most likely the sending unit is bad, which causes the gauge to peg past full, and if you've got it out, change it. My rear tank gauge does the same thing, but the pump works fine. I run about 240 miles and then switch to the front, or run it til it sputters and then switch. Rock Auto sells the sending unit, but it's almost as much as a new pump with the sending unit included. I'll deal with it til the pump dies or I have to pull it for some other reason.
