30A. Radioshack sells them, they're a few bucks. It's really super easy to do. Hack the stock wires off the plug end. Tie these to the relay trigger side. Run thicker wire directly from battery to transfer side of relay. Run a thicker wire from other transfer side to pump. Voila, thick wire feed being relayed to pump. Now just ground it on a seat bolt or something.

 

hum?maybe i should have ran bigger wire to with my install?but i hear it wasnt need for it,but is a plus to have.

 

You are running 2 fuel pumps?

 

thanks guys. i just did this yestarday. ill let yall know how it worked

 

Yes.

 

2 walbro's or a stock and an aftermarket?

 

255HP in the tank and a 290 inline

 

Ok, maybe this is a stupid question but when guys run 255's do they usually leave the stock pump in and just run the walbro inline?

 

no

 

Hes rtight man, just put a 255hp in the tank... Theyre good to 600 ish whp with the right injectors (1000s) using all stock fuel lines....
