12-22-2010, 01:47 AM
on my 89 firebird (no ls1 yet) im still running the stock 305. my fuel gauge is stuck on full. the car runs great so i know the eletric pump is good. what i wanna know is does anyone have the wiring diagram for the pump/sending unit?
im gonna run another gauge to the sending unit to see if (hopefully) its just the gauge. a new sender is 189.99 and i dont wanna have to dish out that kinda dough this close to xmas :/ any ideas??
