Where did you get the braket for the dauls?

Hose clamps. Seriously. https://www.nopistons.com/forums/pub...IR#>/boink.gif

How'd you wire it for a constant 12v? Any easy trick to it or do you run wires from the battery?

with a relay. https://www.nopistons.com/forums/pub...#>/biggrin.png

I also have a walbro pump in my fd with no problems whatsoever.

thanks i'm going to order one, how much hp do all the guys with the walbros have?

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.

how would i go about wiring up a duel set-up?

I also have one in my gas tank.

I never had any problems with it.

Install was pretty simple aswell.

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.

I'm interested in seeing a wiring setup for the duals.. I've heard you can jumper the second off the first, but have also heard NOT to do that... Comments?
