ok first off i left my FP gauge at my friends garage and couldnt get it this weekend, so i tossed the damn regulator in anyways. does any one know which direction to turn the adjustment so to give it less fuel (do i drive the adjustment wheel into the regulator or take it out?)

And secondly the adjustment wheel hits the bottom of the plenum? why is that? and can i grind down the plenum a lil to get some room?

Thanks matt

 

Out, just like any other regulator.
Why? Bad design by holley. You'll have to grind the plenum a bit to get the clearance you need, yes.

 

I also have a Holley AFPR, but I do not have a clearance problem with mine. Theres plenty of room to turn it up or down. Wonder why theres a difference.

 

Same here...I had the holley afpr before switching to HSR. There was no clearance issue on my 85Z28. It uses a dial to make adjustments. All the other brands you have to turn a bolt that is sticking out the top of the regulator. Those hit the plenum. Thats why I originally switched to Holley's.

 

my AFPR on my stealthram fuel rail is a PAIN in the **** to get to, even with the distributor out and the vacuum lines gone. what a stupid thing!

 

Some guys with HSR installed their fpr so that it faces out instead of in for easier access. I installed mine according to instructions but now wish I hadnt. However, I have not had to make any adjustments on mine whatsoever! It holds a steady 40 pounds with vacuum lines connected.

 

Chances are the dial is open all the way thats why its hitting the plennum, If its stuck you're gonna have to remove the plennum and close it all the way, then start over the process.

 

Not all year plenums are made alike.

On my 89 plenum, no clearance issues.
I am now using a pre-89 plenum that I grinded about an inch off of for clearance.

 

Installing my Holley tonight. What is the best way to break off the little tabs in the center of the torx screws holding down the cap? I'm afraid to damage the threads....

Flat screw driver and hammer?

 

Just go to Autozone or something and get the right torx drivers for those screws. They have a hole drilled in the middle of them for exactly that reason. I think the set is about $8...

Hmm, maybe i'll check what our local parts stores have. In the instructions, it actually says to use a small punch. I don't really like the sound of that. Do I just punch them out from the side with a hammer and punch?

 

No, as mentioned you use the proper safety torx bit.

 

Just do what Morley said. I just put on a Holley APFR last month and if you use the safety torx screw bit the screws will come out easily. I did have a problem with tightening the screws in when I put it back on though. For the bottom three screws I had to put on an extra washer so the it would be screwed in as tight as possible.

 

Installed it last night. One thing i noticed is that i had to turn it in quite a bit to get the stock reading which was about 47psi with the vac line disconnected. Does that sound normal for a 305tpi? It still turns but is at the point where it won't go much higher than that (or, it is quite difficult to turn that's for sure).

 

47psi is an improvement over stock, but you should have that pressure with the vac lines hooked up. with your vac lines hooked up now it might be as high as 60psi or close. for a stock setup TPIS suggests running 46 psi and anything higher is more for modded engines. you really should put the vac lines on and reset ur pressure. the best way i found to adjust the regulators w/ bolts is to use a ratcheting wrench. good luck.
