Not a Holley filter. Its a NAPA gold filter. Wrong dimensions. I need a different bracket to install it.Took over 2 months to get it.

Napa part not Holley

Perfect replacement and fit. exactly like the original.

Has a “NAPA” part number on it so not sure if it’s actually the same one you can get for much less money.

Thank you very much
Larry –
Open up the box and the filter has NAPA name and part#. Disappointing
Some guy on the internet –
Using it for a Holley sniper fuel injection set-up. Can’t find a pressure rating for this fuel filter anywhere. Seems to work ok. I won’t be buying the “Holley” box and just buy the same filter cheaper from napa.

Dropped it while installing it, now it rattles and I can easily blow throw it with no restriction. Going to get something a little more durable.
