Car is roommate's, under 100k miles. i suspect that the pump may have burned out from fuel starvation (with high gas prices and all). AAMCO quoted him 800$, $400 of it labor, so i guess the gas tank had to come off. What's involved (timewise) if someone has 1st hand experience with somehting like this. the autozone instructions call for a chrysler fuel pump wrench. will the generic pump wrench from autozone/advance auto work for this? thanks.
