I just installed the full blown double pumper hanger.

2 questions now.

I have a hobbs switch to use so how should i go about wiring that up? Should i run new wires for both fuel pumps? Or can i tap into the harness

Also my fuel gauge is not working now after tapping the harness. What could cause that?

 

Anyone?

 

well it depends on the pumps you used, but if they are walbro 255's then you can have one on the stock circuit and the other hooked up to the new wires / hobb switch. As far as the fuel gauge goes, unless you accidently tapped into the wire for it instead of the pump i would suspect there might be an issue with the install itself. You should probably pull the assembly and make sure its not binding up or any other obvious problems.

 

Where do i run the new wires to for the pump? I think im going to skip the hobbs since i have a fuel lab fpr

 

You do not want to run both pump at 100% the whole time.

You will need to run new positive and ground wires and a relay.
