Fuel Pressure Regulator 7.3L

Features and Benefits

The FASS Fuel Pressure Regulator is for use on Dodge, GM, and Ford 7.3L applications. Engineered from quality 6061 T-6 billet aluminum stock and features full adjustability from 0 to 100 PSI in the FASS diesel fuel system. Contains a 1/8″ MPT boost compression port which grants better fuel pressure regulation from idle to full throttle. This fuel pressure regulator is constructed with 1/2 inch MPT inlet and outlet ports.

Some of the benefits of installing a FASS Fuel Pressure Regulator are the ability to fully adjust the fuel pressure in your FASS system, above or below what it was initially designed for. This product has a boost compensation port that allows boost pressure from the turbo to be directed to the FPR-1001 which momentarily increases the pressure the FASS system produces. When installed with the boost compensation connection this system will allow the fuel pressure and PSI to stay consistent when at open throttle without a drop off in pressure.

Four year warranty!

The FASS Fuel Pressure Regulator is covered by the manufacturers four year warranty after you fill out and return the warranty card. This the only fuel pressure regulator to be covered by this type of warranty!

What is a Fuel Pressure Regulator?

A fuel pressure regulator is a device designed to uphold a consistent fuel pressure for correct fuel atomization. More fuel is going to the fuel rail that needs to go there, so a regulator preserves a certain amount of fuel pressure in the rail then returns whatever else is left to the tank.

How does it work?

Inside the regulator casing is a spring that pushes against a diaphram. The fuel pump has to generate enough fuel and enough pressure to overcome the spring pressure. The left over fuel is then sent back to the tank through the fuel line return line. When your truck is at idle, there is less pressure against the fuel coming inside the regulator because it has a vacuum hose attached to it inside the intake manifold. When you apply gas and the vacuum drops in pressure, the fuel pressure increases to let the engine access more fuel when needed.

What signs will there be when my fuel regulator is failing?

Lack of fuel pressure or excessive fuel pressure are a big tip off. There may also be black smoke or an  instant drop of fuel pressure once when your truck is turned off.
