I just finished putting it on and the cap won't unscrew far enough to bring the pressure any higher than 20psi. The cap hits the plenum.

Anybody have a similar problem or is the 85 TPI different than other years? I'll have to wait until tomorrow before Holley tech support can get bitched at.

You're supposed to screw it IN to raise the pressure, and it shouldn't even be able to go below about 36psi. I think you have problems elsewhere.

 

The old AFPR was broken, but worked well and put out 47psi. I didn't check it without the vacuum, cause something seemed wrong right off. I'll take another look at it tomorrow, but there is still almost no adjustment that can be physically made.

 

Took a look at it now, cause this is bugging me.

Ok, without vacuum it's the same thing.

 

Have you tried screwing it IN yet?

Yes I did, but I thought it was in all the way. It seems I cross threaded the cap. Oops.

Took a fresh look at it this morning and saw it looked crooked. Guess I was kinda tired last night....

 

so is everything ok?

 

Yeah seems to be, just another case of me being an idiot.
