Small, Powerful Fuel Pump
New more efficient fuel pump supports up to 800 hp in street rod, street/strip and road racing applications.
By upgrading its 600-A fuel pump with -10 inlet and outlet ports and fitting it with revised end caps, Weldon racing found the bigger ports allow the pump to draw more fuel, to deliver more fuel, and to do this at reduced amperage draw. The 600-A was previously equipped with a -8 inlet port and a -6 outlet port and the end caps were gold. The new A600-A is distinguished by its black-colored end caps.
This continuous-duty pump, the standard in quietness, is designed for street rod enthusiasts, street/strip proponents, road racers, off-road racersin fact, anyone with up to 600 to 700 horsepower (fuel injected) or 800 horsepower (carbureted). NHRA champion and distinguished engine builder Jeff Taylor has two customers already running them in NHRA Stock Eliminator. Further, the A600-A is the mainstay of Hilborn’s electronic fuel injection market.
With carbureted applications, the A600-A should be used in conjunction with a bypassing regulator such as Weldon’s A15 or A30 and a blocking regulator (Weldon A2046). Weldon heartily recommends the installation of two fuel filters: a 100-micron filter before the pump and a 10-micron filter after the pump.
Because of Weldon’s distinguished aerospace background, every fuel pump receives its own serial number and a corresponding flow chart. All Weldon pumps are tested with actual fuel, not testing substitutes. In fact, they take these procedures even further, testing their pumps, if necessary, to accommodate specific customer requests. Whether running 89 or 93 octane or Sunoco GTX 260 NASCAR-spec racing fuel, Weldon certifies that its pumps will meet the task assigned. As supplied with each pump, the test chart for the A600-A reveals minimal amperage draw. Fewer than 5 amps generate 42 PSI (most common setting for EFI cars) and deliver more than 75GPH.
The internals of the A600-A pump are contained within Weldon’s familiar Type 304 stainless steel housing with end caps made of 6061 billet aluminum. The fuel-cooled continuous-duty motor drives the pump element via spline engagement. The pump element is located at the inlet end and is sandwiched between top and bottom 0-ringed housings made of 6061 hard-coated anodized billet aluminum. The pump element (ring, blades, and rotor) are steel and are precision-lapped like all moving components within the pump.
The A600-A is priced at $325.00 and available for immediate delivery.
