markpwhit Posted May 2, 2017 Share Posted May 2, 2017 Need help to confirm. Need to replace fuel pump on a B model that is 12 volt positive ground. Existing pump is a new modern version that is about 10 years old. When wiring a replacement, does it need to be wired in reverse polarity - meaning the hot wire from the pump needs to be grounded and the ground wire from pump is wired to the hot off the truck. Thanks in advance. Quote Link to comment Share on other sites More sharing options...

41chevy Posted May 2, 2017 Share Posted May 2, 2017 Exactly, Also confirm the pump is pumping to the engine after you got it in.
