Hi all, new to the forum here.
I am restoring a 67 with a 210 hp 327 with the Rochester 2GV 2bbl and am down to the engine detailing. The original pump to carb line is long gone but has been replaced by a 3/8 aluminum line that was hitting the air cleaner housing. The people that did the aluminum line also bashed the air cleaner housing so it would clear. :sad: I am also looking for a housing if any of you guys know where to find one... Anyway, I ordered what I thought was the correct line from Ground Up and it doesn't appear correct. First, the line that is currently on the engine has a 90 degree bend going to the carb fitting and the new line looks like it should have a 90 degree fitting screwed into the carb fitting and oriented down to hook up to the new line. Does anyone know if there is supposed to be that 90 degree fitting on the carb? Second thing is is the line supposed to be 5/16 or 3/8? I am fairly certain this car was built early in 67 (maybe Jan or Feb), the last six of the serial number is 160736. I am under the impression that the early 67 cars had a 5/16 and after April they used 3/8, is that correct or is the line bent differently?

Here is a pic of the car cause I know people like pictures. :D

Thanks for any assistance!

First - Welcome to Team CAMARO :hurray:

:cool: We L-O-V-E pictures of Camaros :D
Very nice looking car!


:yes: The 1967 Rochester 2-GV used on the 327/210 set-up had a 90-deg. fitting at the fuel inlet to adapt to the fuel line connection.

The center carb. in this photo has it - Auto part Engine Automotive engine part Carburetor Vehicle


This is the general routing of the line - Land vehicle Vehicle Car Motor vehicle Auto part


If you have an "Assembly Manual" (AIM) then you can find the fuel line info in UPC-6 procedure C4 ...
But since the carb came as an 'assembly' to the Engine Dress Line for installation, it is shown but not listed ...


The air cleaner housings can be found at many wrecking/pick-ur-part yards - try looking at other 66~67 vehicles, like trucks-Nova-Chevelle-Full Size as they used the same housing.
The last one I found came from a 1966~67 Impala and was in perfect condition :thumbsup:

Thanks for the car compliments and assistance, it makes sense there is the 90 fitting on the carb. Is there anywhere that lists the spec for that fitting? It looks like the fitting on the carb (the one that holds the fuel filter in) is made for an inverted flare, will a 3/8 NPT thread into that?
Also, any thoughts on the differences between the pre April post April fuel lines? Or is it just the 90 degree fitting?

The adapter fitting into the carb is female NPT on the originals and accepts the NPT male threads on the 90-deg. fitting.
It is tightened to line up correctly.
I would imagine any good parts store with a Dorman/Weatherhead fittings selection would have one.

I'm not sure about the exact date and reasons for the 2-GV in late production fuel lines, but I suspect it was to change to the 68 style with a 3/8 compression fitting into the side-feed and eliminate the fitting.

That would be a good question for the CRG folks that may have an actual Service Bulletin stating reason(s) ... it's a little before my 'line-time' ;)

Sounds like I shouldn't have a problem finding one, heck I probably have one in my bucket of fittings.

CRG? Is that Camaro Research Group? I need to do some digging for an AIM, sounds like something I need.

I see in your sig that you have some floating V8 things, any of those of the flat bottom persuasion?

I scrounged up a fuel line to see if the tube fitting would screw into it and seal. I don't think it will because the tube can still be moved with the fitting threaded on. I might have to stop by a fitting store to see if I can find a 90 degree fitting with male 3/8 NPT and a female 3/8 inverted flare. Hopefully the picture will help my explanation. :D

I also sent the guys at CRG an email, maybe they can help me out.

This is a link to the CRG discussion forum. It's more like this site as it has topics you can post in or, if you're a member, start. http://www.camaros.org/forum/index.php

While you'll no doubt get an answer here (lots of folks on both sites) it never hurts to have too many sources.

Justin I got your email so you should have your answer by now, but just an FYI to anyone else that may be curious, the "early" cars (up to approx mid April, 1967) used the 3892640 pipe which was 5/16" in diameter. "Late" cars (after approx mid April, 1967) used the 3917695 pipe, which was 3/8" in diameter.

You have an "early" car so you should have the 3892640 (5/16") pipe.

Sorry to resurrect an older thread but I need a bit more clarification. Is the NPT portion of the 90 degree fitting 1/8 or 1/4 NPT?
I have a new 5/16 fuel line and found a fitting but it has a 1/4 NPT and the only carburetor inlet fitting I can find has 1/8 NPT female threads.
Thank you.

Thanks for the reply James but I don't see a picture. I picture with the breather off might help though. Can I get you to put a pair of calipers on the exposed threads outboard of the big fitting that screws in the carb so I can tell if it is 1/4 NPT or 1/8 NPT?
Thanks,
Justin

I measured the exposed threads on mine that connect to the 90 degree fittring and it measured .465 approximately. Not sure if those are the threads you need measured or the threads that screw into the carb itself... My tube below the threads starts out one size then steps up to a bigger size on the OD from the inlet. I have attached pictures for you to review. 1967 LF7 camaro with the 2 Jet Rochester carb. there is a sticker on the carb that says remanufacture but the top of the carb says GM 2 Jet Rochester Made in the USA so assume the same. Hope this helps and let me know if you need anything else.
