Look on your PCM at pin #19. Should be orange and light green.

Pin 80 which should be light blue/orange is the fuel pump relay control.

So how would I wire it as far as running new wire to the pumps?

I don't see the stock wiring having any issues supporting a walbro 255 with a stock blower.

I did a lot of work to mine and ran 10ga to the pumps which tees off into dual 14gauge for each 255.

I'm running a single walbro 255 on all stock wiring if that helps at all. Just swapped out the pump and slapped a new filter on it. Runs fine... Except for my lean issue and the misfire lol

I'll be running dual 255's. Do you foresee any potential voltage drops or amperage issues with 2 pumps pulling? I know I'll have to buy/fab an adapter for the harness plug at the hat.

I have a few pig tails laying around. I would suggest changing up the wiring a bit.
