At the Greenville Regional my 64 FI with a 7380 unit on it was dinged because the PVC fitting on the front of the plenum (pic attached) was stamped "P" when it should be "GM". I've done some research and cannot find anything on this and no example picture. My only other reference is an ebay posting for an NOS Part 3853720 which says it is for carbs and has the same P but on a different surface. Would some please post a pic of the right part and, if you have one to sell, send me a private email.

Re: 64 FI PVC Fitting Logo
I believe this one to be original, it has never had a deduct. -
Re: 64 FI PVC Fitting Logo
And mine, original, only has a single P on that top area. Wait for John to comment - he's seen hundreds of these.Comment

Re: 64 FI PVC Fitting Logo
My 380 unit also has a smaller 'P' on the top side of fitting.1964 Red FI Coupe, DUNTOV '09

Re: 64 FI PVC Fitting Logo
Hi friends, I have seen posts like this a while back on Corvette Forum. In fact I was misquoted big time but kept quiet.
Plenum restrictor fitting on a 7017380 unit on '64-'65. Various logos.
We think if one has a "P" on it that means Paragon Repro during the days of Richard Fortier. Incorrect.
Here's what I have seen.
P
P with circle
GMGMG
And the coolest of all is a combo of the above.
GMGMG and right next to it: PP and 1/2 of a P. Those three P's had a circle around them. I wish I could say that better.
Trying to say two logos of one side of the fitting. The side that doesn't show. Two rows of logos.
Besides the logos you have to look at the configuration of the fitting. Most of the repros are not made correctly.
Make sure your fitting has a restrictor hole on the end.
A while back a Pittsburgh Tri-State chapter member had a '64 that was really running horrible. I noticed a bare brass fitting in the front of his plenum. I asked him if I could pull the hose off. When I did I whistled as all he had was an auto store fitting with a huge open hole. :}
Meanwhile I don't get involved with judging stuff and in fact at an NCRS show if I open my mouth I would get hollered at. J
(Fuel injections from RP are not consistent gang. Expect most anything and don't be quick to say its incorrect. )

Re: 64 FI PVC Fitting Logo
John, Alan Drakes fitting dates back to the 60s on his 64, when did Paragon market theirs? Alan believes his original to his car. Might need more research etc. on this.

Re: 64 FI PVC Fitting Logo
So here is mine so one can visualize it, sorry about poor picture.
Also have a 63 unit with the "P" (acquired in early 70's), but no idea on history. Friend was going to add to an engine to inject water however car was stolen before that happened so I acquired.Comment

Re: 64 FI PVC Fitting Logo
A couple of things:
1. Dan, your question to John: I'm pretty sure he's saying the P=paragon in not correct.
2. the attached is available on ebay for $145. Note P on side surface. This one and mine likely stamped after machining.
3. the pic of the GM/circle P combo above I think shows that the logo is put/rolled on the aluminum bar before maching. There was one on ebay for $25 nos with just circle P but on the surface drilled for the restrictor nipple. I think it was on the bar before machining also.Comment

Re: 64 FI PVC Fitting Logo
Here's the one with the circle P...note that it is both above and below the nipple. It took me awhile to find it on ebayComment

Re: 64 FI PVC Fitting Logo
Just spoke with Richard Fortier and he added some input to the question of the 'P' being his logo or not. First, his logo was PR inside a triangle, never a 'P'. The P is for Precision Machine in Michigan who was one of 3 GM suppliers for this part. Richard had them remake the fitting in the 80s, only difference was the small orifice had a sleeve in it, originals are solid then drilled to correct size. Richard said a 'P' or circle 'P' were the same company. For Judging, it is one of the possibilities for original fittings.

Re: 64 FI PVC Fitting Logo
If you see one of these fittings with just a "P" on it don't discount it and think it's a Paragon fitting.
I have seen originals with just a "P".
I talked with Richard Fortier about these fittings. I don't think he will mind if I talk about him and this fitting to clear this issue up.
The so called repos that Richard Used to sell when he Paragon were made by the original company from back in the day. So if you are lucky enough to have one then it's a winner.
If the fitting was a repro from Paragon it would have had PR on it.
Richard I know you are looking in. Please correct any misquotes I have made.
This fitting was used on millions of carburetors. Most of those were brass. The fuel injection fitting was plated.
There is along list of logos for this fitting. See my earlier post.
P
(P)(P)(1/2 of a P)
GMGMG
GMGMG and right next to that (P)(P) and1/2 of a P. No circle on keyboard but pretend those were circles around the P.
Don't discount another logo. Richard and I talked about it but I forget.
So basically give credit for ALL logos on this fitting.
And one last thing. Pay no attention to what side of the fitting the logos were on. They could be anywhere on the fitting.
You NCRS guys and your fittings a customer told me recently. But that's what makes it fun I told him.
Make sure your fitting has a resistor on the end where the hose goes. I think it's a .070
That's much more important than logos. John D.Comment
