Converting a Dodge RAM 1999 RAM fuel pump wiring harness to Dodge RAM 2500 5.9Does anyone have the wiring diagrams for fuel pump harness on these two vehicles I am trying to in a jam use a Dodge 1500 fuel pump although it only has four wires and the original 2500 pump has six. I was hoping to use it until I can afford the a new 2500 pump. The wrecker only had a 1500 so I picked it up for 20 bucks hoping to do a temporary fix

I hope it will work although it may not due to different viscousities of the two fluids. Theres for sure a reason or they would all be the same pump. Will it even fit in the tank, and seal up?

Does the diesel have the pump in the tank or on the block? Dont put that pump in the tank if the diesel pump is still in the block. I have a stocker you can have to get you going.

Actually I don't think it will work at all because gasoline fuel injection is roughly 40-50 PSI and the diesel lift pump is only 12-15 PSI even if you did get it to work the pressure would be too much for the VP44.

My Dodge is gasoline so it the pumps
