Description
TSP's 58 PSI fuel filter regulator is a great way to get through your LS engine swap fuel-system setup. This Corvette-style filter has a built-in regulator, with a bypass design running one inlet and two outlets — one to the engine and a return outlet to the tank.
This is a return-style regulator — it requires a return line back to the fuel tank and is not compatible with returnless fuel system designs. For the regulator to operate at its rated 58 PSI, use a 3/8" return line and mount it as close to the fuel tank as possible.
A paper filter element (5-micron) and mounting bracket are included; fittings and clamps are not included and should be sourced separately. Commonly used for GM LS-style engine swaps, street performance applications, and custom fuel-system builds.
Applications
Universal, gasoline only. Commonly used for GM LS-style engine swaps, street performance applications, restoration projects, and custom fuel-system builds.
Regulator Type
Return-style — requires a return line to the fuel tank. Not compatible with returnless fuel system designs.
Sizing
5.660" overall length, 2.175" outside diameter, one inlet, two outlets, 5-micron paper filter element, 58 PSI maximum.

Q&A
Will this work with a returnless fuel system?
No — this is a return-style fuel pressure regulator and requires a return line back to the fuel tank. It is not designed for returnless fuel systems.
How do I get this to regulate at 58 PSI?
Use a 3/8" return line and mount the regulator as close to the fuel tank as possible. Return-line sizing and regulator placement can affect its ability to maintain the rated 58 PSI pressure.
Does this include the filter element?
Yes — a 5-micron paper filter element is included, along with a mounting bracket.
Does this include fittings and clamps?
No — fittings and clamps are not included and must be sourced separately.
What engines is this commonly used with?
It's commonly used for GM LS-style engine swaps, but it can also be used with other compatible gasoline fuel systems that use a return line and require its specified fuel pressure.
