As stated you could also put 2 Walbros in your fuel bucket. I got a junk tank and cut the pump hole portion out and welded it into my stock tank. I didn't want 2 pumps in the bucket. I have -6 fittings on the pump modules going to a "Y" block with -10 out and up to another "Y" block that feeds -6 to each fuel rail. My setup should support about 700 fwhp (1 stock pump and 1 255) The 255 turns on at 4 lbs boost.

You're lucky to have a metal tank so you can weld stuff on it. Nice setup and job, by the way.
