The adjustment screw for the AFPR is tight agains the plenum and I am running 80 psi with not ability to adjust? What did I do wrong?

 

I was able to turn it some to lessen the pressure to 65 psi, but it looks like if I go further I well bend the adjustment screw against the plenum!?!?

 

well, I found out after searching for BBK specifically, others have had this same problem and the vacuum fitting pulled off like others have too. I am sending it back to Summit for a Holley. Unfortunately when I searched for AFPR, some sob said that BBK is great, and affordable. There is too much to wade through in this site sometime.

 

is 512-501 the right part number for the Holley? Summit lists it for the 305 TPI, I just dont want any more problems.

 

well some people have had problems with the holley aswell.with my BBK i just grinded the screw down so it wouldnt hit, but i also had the problem with the fitting coming off. my dad has a tig welder so i fixed it aswell. the problem i heard about holley was that they could not get the pressure up. somthing to do with the diaphram?

pick your poison oh it should be the same part for both the 305 and 350
