Heres the story, I have been running a Holley Blue fuel pump along with the In tank lift pump that was installed by Dodge under warranty before I bought the truck.
Lastnight I lost fuel pressure, thankfully right in the driveway. The holley Blue tested out fine, howver the in tank pump is not turning on. and im gettin plenty of volts to the intank pump...
Im tired of dealing with holley issues and the intank setup.
I have a Draw straw V from Vulcan and I also ordered a Pure flow (Air Dog) FRRP (direct replacement)
I have it planned out in my head, however when i look at the factory wiring harness for the factory lift pump on the block. Im only seeing one red wire. which is sent to the relay for the intank pump. Did they do away with the ground wire when they did the conversion?? If so would it just be easiest to jump a ground to say the battery or frame for the new FRRP pump?? Id like to hear some input, if ya dont mind...? I appreciate it!

 

I put the FRRP in a few weeks ago, but mine had no custom wiring, it just plugged in.
