80 psi / 5.5bar Safety Overpressure Regulator

80 psi / 5.5bar Safety Overpressure Regulator

Part Number: 63103

Product Info

Aeromotive Part Number: 63103
Legacy VaporWorx Part Number: FPRGM5-5.5BAR

Do you have a modern Mopar or GM engine where the supplied wiring harness has a Fuel System Control Module/Fuel Pump Pressure Module/Fuel Pump Control Module?

These are great systems, but to operate properly a safety overpressure valve is needed to keep the engine-off heat soak fuel pressure from becoming excessive. Heat soak overpressure will occur if a safety overpressure valve is not used.

It is common for heat-soak related fuel pressure to go over 200psi if left un-checked.
This part will provide 85psi/6bar required safety overpressure regulation and will prevent heat-soak related hot start problems.

To mount the regulator, use a Radium Engineering fuel pressure regulator body P/N 20-0014 – No Top.

NOTE: This part is not needed when using a modern OEM fuel pump module like the ZL1, Ford GT, etc. They are built into the fuel pump module.
