On 3 Performance Twin 320lph Universal Fuel Pump Assembly

(5 customer reviews)


After working with many cars and attempting to retro-fit multiple pumps into a fuel tank, it was clear there needed to be a solution.  Goodyear sells hose they “Claim” is submersible and designed for in-tank usage.  We have ended up stranded and needing to be towed home 2 different occasions using that fuel hose within a few months.  At that point the wheels started turning and ideas were coming to us for a new product.  The idea was to eliminate the need for the hose sections and only need one short amount to extend from the pump assembly to the factory fuel hat.  We primarily ran into this issue with the 1500 / 2500 truck fuel pump upgrades.  So this is ideal for the guys running our system and wanting to add twin pumps and have the most trick setup on the market for the application.  Keep in mind though, this is a completely universal setup, if your modifying a tank or just needing to retro-fit a set of pumps into your application, review our measurements to see if it will work.

What we did is designed an assembly that will hold the pumps in place and then designed a billet merge block that is 0-ringed and designed to slip directly onto the On 3 Performance 320lph (e-85 safe) fuel pumps.  This way there is no fuel hose needed, clamps to come loose, hose to rupture, etc.  We have bench tested at 60psi base pressure as well as with our shop truck and its flawless.  This is as simple as it gets and eliminates all the issues that people face when doing a dual pump assembly.

We all know how much fun it is to dig around in a fuel tank to upgrade the pump.  None of us want to do it multiple times or get stranded due to faulty items.  This is the simple solution so that you do it once and you do it the right way.  There isn’t anything else like it available on the market and you will save yourself a lot of time and headaches by using this proven fuel assembly.

Here is a quick video clip showing the assembly getting powered up and the prototype pumps.  Note the color is different on our production fuel pumps with logo but this is the exact assembly that we bench tested and designed with:

    How much hp will it support on e85?

    • admin

      We have been up around 850 rear wheel and that seems like the area where its maxing out on e85. 850-900 wheel HP is going to be the limit

  2. Omar Rivera

    Does this include the fuel pumps?

    Will this fit in a stock tank of a 2003 silverado?

    • admin

      Yes that is what we designed it for and what we use it in

    Can you buy just the bracket assembly?
    Is that 600hp though the stock lines?
