    No issues whatsoever.

    High quality. Ran this from the electric fuel pump to a Edelbrock 1406 carburetor and it works perfectly. Adjusted it to send 5.5psi at all times and never had an issue.

    Works well

    I added this to a high pressure fuel pump to reduce the pressure for a carbureted engine. It worked as advertised.
