    I just ran across this while researching a Turbo Small Block Chevy project and thought I should share, dual pumps in the same housing, wired so they can be staged on one at a time or both run full time. Can be used submerged or inline. Applications up to a claimed 1800hp on an EFI system and e85 compatible: Holley Performance Products Dominator™ In-Line Billet Fuel Pump (Hi-Flow)

    Looks like 2 walbros in a fancy case to me.

    For comparisions sake;

    * Holley pump costs $300-370. And it flows 455 lph at 80 psi.
    * 2 Walbro 255 in tank pumps cost $200. And together they flow 385 lph at 80 psi.
    * 2 Walbro 255 in-line pumps cost $230. And together they flow 458 lph at 80 psi

    So the Holley pump flows about the same as two Walbro 255 inline pumps plumbed parallel, and the Walbros are about $100 cheaper. But the Holley pump requires no bracket to mount and requires no y-block or extra hose ends to plumb. So, that difference of $100 could easily diminish depending on how the Wallys are mounted and plumbed.

    Two Bosch 044's in parallel are still king at $400 and flowing 550 lph at 80 psi. But then again, mounting and plumbing can be expensive.

    What about the other obvious choice... 3 255 walbros? :D Used 2 3-way air fittings and re-tapped them for 1/2" on the inlets/outlets. Very cheap and effective.

    That would definitely be interesting. I'm not sure what that would flow, but it shouldn't have a problem outflowing twin 044's. And 1/4" inlets would probably be plenty large enough on the 3-way as long as the outlet was at least 1/2". That's a neat idea though.

    Paul i see what your saying but that holly just looks awesome compared to making up a way to house them both so i think the extra 100 bucks wins it! Its a great looking bit of kit and i would love for this to be used on our cars if i needed one i would have one great find!!!!!!!!!!!!

    This was on LS1 tech forum. Sounds a bit low to me, prob pick up a ton with 13+ volts.

    Don't have higher pressure/voltage values. Pushed a set of 8 80lb injectors to over 1000whp (e85) with it though. 1/2 lines and 68psi base fuel pressure and 28lbs of boost. (96psi total!) Gotta be flowing some fuel to make 1000+ on e85 at that pressure. :thumb:

    180 gph = ~680 LPH. That's alot of fuel, but ratings at 45 psi are useless to us turbo guys. Either way, I would have guessed around that much flow at 80 psi with three inline Wally 255's.
