sup everyone.
my walbro is currantly wired to the stock relay, and i want towire it with thicker wires like everyone does,
anyone have instructions or can tell me how to do this?

ps, which relay i need?


thanks

 

use your power wire from your existing fuel pump wiring and use that wire as the 12v signal wire coming ito the relay (to turn relay on and off) and a 20-30 amp relay is fine since most walbro pumps are stamped 20 amp. and then after that get your power from your battery or a constant power source with 13 volts to get the best out of your pump. your stock wire to your pump is about 10.5
