C2 fuel line material

[Richard S.]

I have a early Dec build 340 HP car and would like to know which of the fuel lines and fittings are brass or chrome that connect carburetor to fuel bump.

Wow Joe that's very nice work ...

Can't claim that one but here's a Red 63 Roadster with the original owner and his wife!

Re: C2 fuel line material

Am I seeing things? Is this underhood shot supposed to be a 63 340hp? (Fuel hose from pump to filter? Non AFB fresh air hostess?) please clarify. I too have my original 63 L-76 and it didn't look like that and the op's question isn't answered with this shot.

Well Stu, why don't you post a picture of what a REAL 340 HP looks like!

Just wanting to help the guy out!

Please clarify your concerns!

Re: C2 fuel line material

Just 2 simple explanations;

1) The fresh air hose on both 63 L-75 and L-76 Engines (which use 3460s or 3461s AFB's) crosses over the hot air choke tube (not beside it as shown in the photo).

2) A steel tube gas line is used from the fuel pump to the GF-90 fuel filter (not a hose as shown in the photo).

There are plenty of photos out there to confirm this. No need for me to post another (see Noland Adams Corvette Restoration Guide Vol. 2).

I believe what the OP is looking for is the cutoff date from the early production 340hp which had plain steel fuel lines with brass fittings vs. the later production 340hp engines which had chrome fuel lines and fittings.

I wish Michael Hanson was still on here. If the Early Corvette was in fact a 360 HP instead of a 340 HP car then the fittings and the lines would NOT be chrome plated Joe Ray. Whew!!!! True story.

All early cars were bare including 340 and 360.

Stu,
Look a bit closer at the picture. The rubber hose you're seeing is the heater hose off the intake. The steel fuel line is running, what appears, along the edge of the valve cover.

Stu
Thank you. If I can find out what the cutoff date was that would be great. Had an idea the early cars were steel with brass fittings but was not not sure when the transition to chrome took place or if all fittings and lines were then chrome after the cutoff date.
Thanks again. If I can get resolution on this that would be great.

Thanks for correcting me Lief. I'm waiting on my new glasses since having laser procedures and am trying to get by with cheap reading glasses for now.

I know I see well enough to see the mixed up hot air choke tube and the fresh air hose. I'd venture to say this engine may have a Holley on it, not an AFF.

Re: C2 fuel line material

Stu,

What's an AFF?

More info on that carb please!

Re: C2 fuel line material

Ha! Guess I'm the first poster to have a typo on the forum. See my post #7 for clarification.

That's an "Aluminum Four Farrel", don't you know? (I sure would like to know what carburetor is on the 63 in your picture. It's likely not an AFB or an AFF, or an Edelbrock version of either).

Thanks for the sharp Editor's Eye. I could have used you when I Tech Wrote for GM for 22 Years.
