FASS Fuel Pressure Regulator FRP-1001
The FASS FRP-1001 is approved for use with Gasoline and Diesel Fuel. Read below how the FASS FRP-1001 can benefit your car or truck powered with a FASS Diesel Fuel Pump. The FASS FRP-1001 is built with the following attributes:
- The FASS Fuel Pressure Regulator FRP-1001 offers Full Adjust-ability from 0 to 100 PSI in your FASS diesel fuel system
- FASS Fuel Pressure Regulator FRP-1001 is made from Aircraft Quality 6061 T-6 Billet Aluminum stock.
- The FASS Fuel Pressure Regulator FRP-1001 has a 1/8" MPT Boost Compensation Port which allows for greater fuel pressure regulation from Idle to Full Throttle.
- The FASS Fuel Pressure Regulator FRP-1001 is constructed with a 1/8" MPT gauge port.
- The FASS Diesel Fuel Pressure Regulator is constructed with a two 1/2" MPT Inlet and Outlet/Return ports.
The FASS FRP-1001 offers the following benefits when used in conjunction with your FASS diesel fuel system:
- The FASS FRP-1001 allows you to adjust the Fuel Pressure in your FASS System.

- The FASS FRP-1001 allows you to adjust the Fuel Pressure to a higher level than the FASS pump was originally designed for.
- The FASS FRP-1001 allows you to adjust the Fuel Pressure to a lower level than the FASS pump was originally designed for with the replacement of the fuel pressure spring.
- The FASS FRP-1001 has a boost compensation port which allows the boost pressure from the turbo will be directed to the FPR-1001. This will temporarily increase the pressure the FASS system produces.
- The FASS FRP-1001 when installed with the Boost Compensation connection will allow the fuel pressure / psi to remain constant under at wide open throttle without a drop off in pressure.
The FASS FRP-1001 FASS Fuel Pressure Regulator is backed by a manufacturers 4 Year Warranty.
- The FASS Fuel pressure Regulator is protected by a 4 Year Warranty upon completion and submission of the Warranty Card
- The FASS Fuel Pressure Regulator is the only replacement pump available with a 4 year Warranty.
What is a FASS Fuel Pressure Regulator FRP-1001?
The FASS Fuel pressure Regulator FRP-1001 was designed and built to maintain a constant fuel pressure above the intake manifold pressure. The difference in pressure between the fuel rail and intake manifold or differential pressure across the injector should be maintained at a level to suit optimum injector operation and maximize engine performance. Deviations in fuel pressure have a direct effect on your vehicles fuel injector performance.The FASS Fuel Pressure Regulator was designed and built as a superior product with a lower price point.
Why and When do you need to install a FASS Fuel Pressure Regulator?
The installation of the FASS fuel pressure regulator allows for the adjustment of fuel pressure to suit larger aftermarket injectors and other engine modifications. Fuel Pressure Regulators are necessary to regulate and flow increased volumes of fuel pumped by high flow FASS Fuel Air Separation Systems and FASS fuel pumps.
The FASS FRP-1001 works with the FASS Diesel fuel pump to maintain a steady pressure relationship between the fuel line side of the injectors and the intake manifold.
When the FASS Fuel Pressure Regulator is connected with the Boost Compensation Port you can adjust the pressure at idle or full throttle for fine tuning. When the FASS Fuel Pressure Regulator is connected with the boost compensation port it becomes a rising rate regulators commonly called FMU's (fuel management unit). The FASS Fuel Pressure Regulator FRP-1001 will now increase fuel pressure at a direct multiplication factor to the current boost level. So instead of messing with complicated computers and injection duty cycles, these systems just increase fuel pressure to add fuel. The FASS Fuel Pressure Regulator now will this type of connection will only add pressure under boost. So when you are off boost, you maintain factory tuning and drive-ability. Only as you get boost pressure increases does the FASS Fuel Pressure Regulator begin to increase fuel pressure.
THE FASS FUEL PRESSURE REGULATOR FRP-1001 is intended to be used for Moderate to Extreme Power Applications.
