98 Z28 fuel issue please help....
Every after market pump I have put in this car has done the same thing. It lasts about a day or three and then starts to cut out and when I connect the fuel pressure gauge it is half of what it should be. Only pump I have had success with is OEM assemblies. I have already purchased a Walbro 255 and it is doing the same thing. Anyone have any ideas?
