The combination fuel filter and bypass regulator sends 58 PSI (4 BAR) to your fuel rail and returns unused gas to the tank.
Inlet is male 3/8 inch quick connect; return to tank is male 5/16 inch quick connect; outlet to engine is female 3/8 inch quick connect.
Your electric fuel pump works continuously & this bypass regulator passes excess fuel back into the tank so the pump can run freely.
This is a popular fuel supply solution for fuel injection (EFI / FI) retrofits and for swaps to modern engines like the GM Gen III and Gen IV V8 engines in 4.8, 5.3, 6.0, and 6.2 displacement: LS1, LS2, LS3, L76, L98, L77, LY6, LFA, LZ1, LY2, L20, LH6, LS4, LSX, etc. Commonly used in LSX swap. Suitable for primary fuel supply to newer LT1 DGI. Not for the 1990s era LT1! Not recommended for dual pump setups. Not suitable for turbo or supercharged applications, which require vacuum reference
Made of high-quality materials, it has strong applicability, water separation efficiency, and filtration of impurities.
The connected plastic modules are not easy to separate and have strong sealing.
Installation position: on the pipeline between the fuel pump and the throttle body inlet
Purpose: Filter out harmful particles and moisture in the engine fuel gas system to protect the oil pump nozzle, cylinder liner, piston ring, etc., reduce wear, avoid clogging, reduce mechanical wear, ensure stable engine operation, and improve reliability.
The internal air diverter turbulates the air longer and ensures all the oil sinks to the bottom of the can, leaving nothing but clean air to pass through the 50 micron bronze filter to the intake.
An internal baffle keeps the collected oil from splashing around under race conditions.
The can is also washable, unlike many other cans that require you to replace your filtration system.
