I'm about to put a Walbro 450lph in-tank pump in, and was wondering if I could run/extend the fitech fuel pump control wire to a Solid State Relay in back and still use the fitech to control the PWM to the Walbro pump via the SS relay???
I would check with FItech, but I think all Walboro pumps need to be set to 100% Pwm in the handheld, because of the pump design. Then I am sure you can us a relay.
