The gerotor design has been proven to be extremely durable in OE applications. It uses a gear inside a housing that squeezes the fuel as it travels. This design is seen in oil pumps, which is another part that needs to be highly reliable. The design of these pumps enables turning as high as 4,000 rpm, resulting in higher pressure. The fuel lines don’t need to be as large in high-pressure fuel systems when compared to low-pressure systems, so using an HP or Dominator fuel pump can save weight. Furthermore, the gerotor’s tight tolerances and fine balance gives it super quiet operation compared to rotor/vane-style pumps.
In addition to serious race pumps that can support 2,000-plus horsepower, Aeromotive also offers high-quality pumps for your typical street machine. Our HO and SS pumps are designed for deadhead-style carbureted fuel systems. Although they’re not designed to flow as much as pumps like the A100, they’re still built to exacting tolerances for outstanding efficiency, performance, and durability. Both the HO and SS pumps boast all billet bodies and perfectly matched electric components for a truly high-quality pump. What I find crazy is that the HO pump still flows enough to support 600 hp. That is a good deal of power from a very simple fuel system. Additionally, the HO pump is internally regulated to 7 psi so you can actually run this pump without a regulator at all. The SS pump flows even more and can support 750 hp.
Liz Miles: Most hot rodders are already familiar with Holley’s Red, Blue, and Black fuel pumps. They are rotor/vane-style pumps designed to flow high volumes of fuel at low pressures, perfect for low- to high-horsepower carbureted applications. The Holley Red pump flows 97 gph and supports 425 hp, while the Blue pump flows 110 gph and supports 550 hp. Stepping up to the Black pump yields 140 gph and 750 hp. Two more pumps in the medium-sized family are the HP 125 and HP 150. They feature billet bases, and are good for 750 and 900 hp, respectively.
Jesse Powell: When you look at the A1000, Eliminator, and Pro-Series pumps, you are talking about the most popular inline fuel pumps ever. It is very hard to compete with their flow capabilities and their durability. Although we have spent the last several years developing all sorts of new products, they have all been based around the A1000 and Eliminator design. They have just been packaged differently. Whether they are in a fuel cell or built into a system that drops right into your fifth-gen Camaro, they just flat out work. Our new designs have been done to provide users with worry-free performance and easy installation. Rather than hand a guy an A1000 for his Corvette and tell him “good luck,” we took the guesswork out of the equation. These new variants of our inline pumps drop right into your factory tank, use the factory lock-ring to seal, and still retain the tank siphon system and leveling unit. The pump is the last thing you will think about now. In the past, late-model Camaro and Corvette owners had to go with a fuel cell, or with a very expensive multi-pump setup, but with our Stealth systems, they can have serious flow with drop-in installation simplicity.
