Walbro 255 Fuel Pump

I'd say to be Super Safe a max 400 hp with a single and up to 650+ with dual pumps (we haven't found the limit yet). But I'd run duals now because then you'll have enough fuel for anyting thing you'll ever need to do in the future.

The easiest way is to pull the relay out of the black box on top of the radiator (the fuel pump one). pop the black top off it and bend the little metal thingy so that the relay contact points stay connected all the time. Then just put the cap back on and plug it back in.. Walla 12v all the time.. if sombody want's to pop the top off and take a pic and post it I'll modify it and show you where to bend it at.
