AFPR Quick Question

83 T/A with CFI
I dont have a lot of experience and I'm trying my best not to mess up any parts so sorry if this is an obvious question.

I am trying to make my Fuel pressure regulator adjustable. Do I need to drill out the black piece on the bottom? I've read the how-to tech write up but I just want to make sure because the little 'cup' came out with the spring so it wasnt pressed in.

Re: AFPR Quick Question

What your trying to do is free the adjusting screw head from the regulator body.

Use a drill size that just fits into the hole.
