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 The original pump to carb line is long gone but has been replaced by a 3/8 aluminum line that was hitting the air cleaner housing.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.

Thanks for any assistance!
Justin

First - Welcome to Team CAMARO :hurray:

We L-O-V-E pictures of Camaros

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 -

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:

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'
