Vapor Lock Resistant Fuel Pressure Regulators

Thomasville, North Carolina – Race Pumps regulators are now available with an optional “idle bleed” to prevent vapor lock with today’s fuels.

The idle bleed is simply a -4 (1/4”) AN fitting than installs in the side of a Race Pumps regulator to return fuel to the tank. The carbureted versions have a #70 Holley jet installed to meter the flow…..the EFI versions have a #40 Holley jet.

Gasoline is more vapor lock prone than it was just a few years ago. E-85 and methanol are even more temperature sensitive. These fuels can vapor lock at temperatures as low as 150 degrees F!

Fuel returning to the tank keeps the fuel within the engine compartment cooler at low speed and idle. If the fuel is stagnant and the engine compartment reaches a temperature that is higher than the boiling point of the fuel….it’s going to vapor lock.

A simple solution to a complex problem.
