FAQ

We are the same Baker Engineering that still builds engines. While the landscape of racing has changed since we were founded, we are still here pushing the limits of horsepower with engine builds, performance products and tuning solutions, primarily for domestic V8 applications.

If your vehicle is powered by a GM, Ford, or Chrysler V8 engine, almost certainly. Tuning can also be performed on vehicles with Motec, Holley, and select other aftermarket ECU’s. Outside of that, feel free to reach out for more information.

We do not offer a rebuild kit but we do offer a rebuild service. Reach out to us to set up a rebuild, we generally offer 1-2 day turnaround and can often turn pumps around same day if you give us a heads up.

The holes in the side of the upper body are to vent the chamber above the diaphragm.

Under some conditions, including excess crankcase vacuum, excess crankcase pressure, or failure of the diaphragm rod seal, oil may make its way into the upper cavity of the pump and eventually leak out of the weep hole. The pump requires a vent to function properly and plugging these holes can cause damage to the pump.

We have re-designed the diaphragm rod to prevent the seal from being displaced by fluctuations in crankcase pressure and can replace the diaphragm assembly during our rebuild procedure. Contact us for more details on this change and how to get your pump rebuilt.

Starting in 2024, we offer the standard valve body and a “stock chassis” valve body to reduce the cases where the inlet and outlet need to be reclocked; however, we also have a helpful video that covers the re-clocking procedure. If you need help, we can talk through the process over the phone or re-clock a pump during our rebuild service – reach out to us for more information!

Baker Engineering’s 7.5 psi PRO/CAM mechanical fuel pumps do not require a regulator except in some cases where they are paired with a smaller 2-barrel carburetor. For most applications our 7.5 psi pump will hold 6-8 psi throughout the operating range with no regulator installed. Our 11 psi and 15 psi PRO/CAM mechanical fuel pumps are designed for higher flow fuel systems where they should be paired with a bypass style regulator. Our new Billet Bypass Fuel Pressure Regulator is compatible with all typical automotive and racing fuels including e85, alcohol, and pump gas and is a perfect match for our 11 psi and 15 psi PRO/CAM pumps.

The listed pressures are nominal output pressures based on a typical fuel system. For most applications if your pump is putting out a steady pressure and not dropping off at higher RPM, everything is OK. In some cases you may want to get a higher pressure pump and run a bypass regulator to get a bit more headroom. If you do see abnormally low pressure, and you have eliminated any chance of fuel leaks downstream of the pump or air leaks upstream of the pump, there may be an issue internally that needs attention. When you send in the pump for a rebuild, we always run the pump across our test stand to verify performance before and after service and can tell quickly if there are internal leaks or other problems.
