I was thinking it was a holley unit, but I'm unsure. It came with it's own diaphragm, which was different at the top. Also, it doesn't have a screw on top, it's got a place that looks like it's made for an allen wrench.

I know holleys came with a Top piece that looks like a cover, that you can turn with your hand, but neither of these have this top piece.

If this is a holley, is there anyway around using it without that top piece?

 

that looks just like my old stock one....


ttt for you.

 

If it is an AFPR and not just a stock piece, it looks like it'd be a Crane unit. I think the Crane is the one with an allen fitting down inside there for adjustment instead of the bolt on top.

 

Looks just like a stock unit that has been modified to be adjustable.

 

It looks like an Accel to me. Mine has an allen head at the top instead of a bolt.

 

It's an accel.

Thanks for the help. Bort Im'ed me last night and let me know. I had never seen one like this, ended up getting two in one week, I didn't know there were three different kinds.

Thanks for the help though.

 

the crane one has a screw stickin out to adjust w/wrench...

 

yep, Accel
