so I feel in over my head and i thought I would ask for some guidance. I have 1982 22R that I just finished desmoging. at this time I'm ready to instal the new Weber 32/36 I got. I picked up a holly fuel pressure regulator and a mr. gasket fuel pressure gage as recommended. How ever I also picked up a carter p4070 inline electric pump to replace my failing stock mechanical pump. I'm trying to figure out how to plumb all of this?? so my questions are...

were should I mount the pump and pressure regulator? frame rail or engine bay?
witch of the 2 fuel lines should I splice into?
what size fuel line do i need?
do I need a return line to the tank? if so how do I go about plumbing that?
I have wired the fuel pump with a relay and spliced into accessory power so it only has power when the vehicle is on. is this correct?
and lastly do I mount my wires above or below my fuel pump/fuel lines?
am i missing any thing??

thanks for helping me not burn my rig down guys!!

 

The pump should be placed as low as possible, and as close as possible to the fuel tank. Electric pumps push well, but do not suck well.

For best chances of avoiding vapor lock, the pressure regulator should be as close to the carb as is practical, so that most of the fuel line is kept at the higher pressure.

I don't know about carbed trucks 2 fuel lines?? You should only need one,

This is my .02 Others will likely pipe in.

 

That makes seance to me ok.

what about running the wireing? do I mount it above or below the fuel lines? Dose it matter?

 

You can run the wiring any way you see fit, as long as it is protected from abrasion and potential fouling by underbrush and the like.

I would say that if you currently have more than one fuel line that enters the tank, only one of them probably has a siphon that goes to the bottom of the tank.

 

The pressure side line is the one with the filter.

How much pressure does this pump put out you want to be sure the filter you are using can stand the pressure
