I went looking through our 'SEARCH' today attempting to find a part number for a HOLLEY specific AFPR unit that plugs into our 5.7 TPI fuel rails. I can only find the part number: 512-501 which is listed specifically for the 5.0 engine.

So I phoned HAWK/JEG/SUMMIT/ and no-one had an answer. I tried calling HOLLEY directly, but they arn't answering their phones today.

Anyone know the answer to this mystery? The ACCEL unit that is on mine keeps loosing parts and I need to resolve this quickly. I'm using a fully ported TPI system, SVO injectors and a PROMSferLess chip/ New ZZ4 based 355 motor going in as soon as I get all the little glitches out of the sensors and such......

Thanks, Nitro-Nicky

It's the same one.
Go for it.
