Aeromotive Inc. Carbureted Fuel System

When it comes to fuel pumps, there are quite a few of them to choose from. When cost is factored into the equation the list gets shorter. I found out about Aeromotive through my local speed shop when they used an A-2000 pump for their own racecar. From what I have seen the Aeromotive pump is amazing value for money. The recorded failure rate on the product line is also reported to be amazingly low. P/N 11202 - The A-2000 pump, fuel filter and regulator look good in their red bright dipped anodized finish. The fittings and hose ends are anodizing black rather than the normal blue and red of their competitors. The pump comes with a bracket but also gives you the choice of mounting it with four cap screws (included) or with two blind holes to facilitate the direct replacement of competitors pumps. The outlet is engraved OUT to avoid confusion and both inlet and outlet ports accept -10AN fittings. There is also a -8AN return line port and a 1/8" NPT port ready to accept a fuel pressure gauge on the upper surface of the unit. Aeromotive literature states the pump will deliver free flows of in excess of 350 gallons per hour, more than enough to support 2000 HP at 20 PSI. As I am starting off with around 940 HP out of my Pat Musi built BBC, there will be more than enough fuel available. The pump is also alcohol compatible. P/N 13203 - The A4 carbureted regulator is a four port regulator that uses a "soft seat" design. It is the only regulator available on the market with this feature. It is designed to give more precise control thereby giving more consistent E.T.s. The regulator bracket can be mounted facing up or down, allowing you to offset the unit to suit your application. The carburetor is supplied from four -6AN ports located below the top plate of the unit. Pressure adjustment is achieved by altering the adjusting screw in the top plate. A locknut ensures the pressure does not move from it's set position. A 1/8" NPT gauge port is located on the front face where the gauge can be easily seen. P/N 12301 - The recommended position for the fuel filter in this application is after the pump and before the regulator unit. Aeromotive's reasoning on this is, the A-2000 pump does not have the tight clearances of the EFI pumps they manufacture and it is more important to stop debris reaching the carburetor and as long as the fuel is filtered on it's way into the fuel cell it will not be a problem. Sometimes filters on the inlet can have too much restriction and cause the pump to cavitate. I chose the replaceable 10 micron paper filter but there is an option for a cleanable 100 micron stainless steel element. The body and end cap both have flats for wrenches, making element replacement a piece of cake. I intend to mount my filter to a bracket and will only have to remove the braided line, hold the body and remove the end cap. I was quite impressed when I saw Aeromotive's braided hose fittings, anodized black the flare unions are really designed for maximum flow. Aeromotive claim they have the smoothest transition available on the market today and I believe them, they really are a work of art. I compared a regular -12AN fitting to an Aeromotive -10AN fitting and you would not believe the difference. The -12 measured .620" before stepping down to .488" with the Aeromotive one measuring .520" before flaring OUT to .700". I feel the extra .032" that the Aeromotive part measures has to be worth extra flow, never mind what the smooth transitions do for the flow. There is a kit available for those who want to purchase all their components at one time. Check out Aeromotive's Universal Kit P/N 17202. The company has a Tech tips section on their website that is worth visiting and if you new any assistance, they are more than willing to help. The company fields an active raceteam and use all three cars as rolling testbeds for their product line. Keep your eyes open for company President Steve Matusek in his Super Gas Mustang roadster and Kyle Fickler in the companies Super Gas Maverick and Super Comp dragster. As I go through the installation of the components on the truck I will add to this article and report on how easy or hard the installation is.

If you have any fuel system questions go to the Tech Talk section and send them to Brett Clow from Aeromotive, he will try and help you out.
