[QUOTE="lincolnlocker, post: 546840, member: 944"] another thing that i found with my pumps when i was doing my fuel system that tarm pointed out to me is the voltage at the fuel pump... mine was only 11.5v... then i added a carter high flow low pressure pump as sort of a lift pump and just piggybacked the wiring... had issues still and couldn't figure out the lagyness of the pumps... thats when tarm said to check voltage.. it was 10.9 at the walbro and 10.3 at the carter. i took the wire off the carter to just test the walbro and thats where the 11.5 volts came from.... so i ran wires directly from my battery's to the pumps fired by a relay and hot dam that made a difference... both pumps see 13.5 -14 volts constantly. all of the high pressure pumps like fuel lab and aeromotive are 13.5 volt pumps so everyone might wanna check what they are getting for voltage.
