Can I get some measurements?

I'll post pics to aid in this soon, but I'm really interested in a few cars from each generation that may have one laying around.

Can you measure the largest diameter flange that sits down in the rail? Also the diameter of each O-ring (don't remove them) and the distance between o-rings? Working on a possibility here......trying to clear some unknown 'air'.

This is what I'm after:

Don't need Series 1 regulator info. Need S2 L36 and L67, preferably from 97 and up:


Is yours close enough to this that you'd say they're identical in dimensions?

Measurements are almost exact except I got 1.352 on the widest part and 2 inches total length with the micrometer.

Edit: The above measurements are for our Caspers adjustable regulator which should fit. The stock S2 regulator is shorter like the S1 you posted.

If you still need uh..that'* a 96 I have laying around...hmmm dunno if it'* the same.

96 L67..tell me if you want the measurements..if so..time to buy the slide caliper

Ok, Todd. I'm probably going to do this. Based on the fit and function, you may be able to edit your applicable years on the Adj. FPR'*.

I know a series II FPR will mount to our rail without leaks... but that'* all I know.

That'* the one you sent to Don? So you did have it in the rail. Good.

Bill, can you measure? Even a good ruler comparo will be good enough.

Yep, ran it for a little while, MPG went down a couple, but I had other problems so I took it out.

Bill W, are you thinking a S2 FPR will solve the lean issues you guys are having with the extra power from the top end porting?

Edit: I'm asking because I'm going yarding this weekend and I might as well grab one if there'* a possibility I might need it later. If not, I'm sure I can either give it to the crack dealer or find someone else who needs it.

No. But stay tuned. Looking at a different option related to this. When know, you'll know. Don't jump on anything just yet.
