Default 8.8 volts at fuel pump

had issues with fuel pump not coming on all the time sometimes it sounds weak. tested voltage at the pump and it shows 8.8 volts. tested repeatedly with all nearly the same results. (i did wait for grid heaters to shut off and rechecked. also checked and load tested both batteries individually both checked out ok) i put 12 volts straight from battery and it runs and sounds fine. to be safe anyway im replacing pump. anyone else have this issue? ECM?? i think im going to leave it on a toggle.

Most people aren't running stock lift pump... I recommend you join the club.

your asking for big money spent later if you don't upgrade your fuel system now

Raptor 100, I think fass makes a similar 90gph as well, not sure about who's cheaper. Go to the "request a quote" thread and get yourself hooked up with one of the forum sponsors, they'll hook ya up with prices and info as needed
