    12-881 is rated 2.7 out of 5 by 3.
    Rated 2 out of 5 by from Holley regulator Low rating isn’t for product quality or customer service, it’s for a misleading product ad online. I purchased the 12-881 as a non by-pass regulator because it wasn’t stated anywhere in the product description as all the other by-pass regs where clearly worded. In the description of the ports...return is mentioned. It’s the only hint it’s a bypass. Now the hassle of returning or suffering loss and throw it on the shelf.

    I'm putting a carburated 302 in a 2000 mustang with a 3.8. I want to use my stock fuel pump, will this work to regulate down to 6psi and return additional fuel back to the tank while not over heating the pump?

    This will not work to convert a EFI fuel pump to a carburetor, you will need a different pump.
