lift pump wiring ?

lift pump wiring ?
I currently have an intank pump that must have been instaled by the dealer under the previous owner . I only get 7psi at idel . I'm re-working the entire fuel system with 1/2" lines , and on the tank I'm mounting the vulcan draw straw .
From the draw straw I want to goto the orignal style factory pump which I'm mounting on the frame near the tank .
Can anyone help me as far as how to wire the new pump and de-power the intank pump ? The whole intank setup will remain where it is and the drawstraw will tap at anoter area , hence the reason for disabling the intank pump .
thx

You need the Vulcan relocation kit as well as the Vulcan Drawstraw to do that. The relocation kit comes with the cable that will connect the OEM style lift pump to the original wiring up next to the fuel filter on the block. You run the wire down the frame & connect it to your pump. The kit also comes with the bracket to mount the pump on the frame rail next to the tank. Unplugging the intank pump from the original plug by the fuel filter will also disable the intank pump. But it might also disable your fuel guage. If you're going to drop the tank to install the drawstraw, you might try to find an original tank module without the pump in it. A little wiring & plumbing and you should be OK.

But I need my fuel level guage to work , so I'm looking to find out how to disable the pump while keeping the guage . Also I dont see an empty harness where the OEM pump used to be , Im not sure how the dealership re-routed the power to the in-tank pump . The tank is droped btw . thx

Hi , my problem is I dont have the original tank module . I have all the plubming worked out though so I can just tap the tank without disturbing the current module .

But his plug will be different. He'll have to trace the wires and find out which ones power the pump, then cut them and splice in a plug that will fit the OEM pump that he plans to mount on the frame rail. That way, his fuel guage will still work! Later on, when he has the cash, he could swap in a FASS or a Walbro.
