Well, after finally running out of fuel today I've decided to replace the sending unit/fuel pump on the GP. The pump still works but I'd rather not pull it twice with the OE pump in there having 403K miles on it, you know that Murphy guy will likely show up soon after. Sending unit has been borked for a while and I'm tired of it. RockAuto has a listing for a DELPHI FG0156 and a ACDELCO MU1727. Anyone have any opinions on which one to grab? Not looking to fab a bunch of crap, just pull it, wire it up if needed and drop it in.
