Ok, so my car has been running kinda crappy lately. Went and checked the fuel pressure. 40 psi at idle.......rev it up and it drops to about 10 psi. Any ideas? Fuel pump and/or regulator?

Filter may be clogging..Usually(at least from a few I've heard of including my own)when the pump quits,it usually just quits.

$7.00 is cheaper than a fuel pump to start with, plus you don't have to drop the tank. Change the fuel filter...

good call-don't forget to replace your fuel tank grommet when you pull the tank, i've already seen three separate times where friends changed their pumps and had the tank pour out profuse amounts of fuel because the grommet ripped...
