I'm aware that the chrome fuel line that gets plumbed into the Holley carb is a Factory Original. Mine leaked at the (fuel) block from the fuel line from the pump, at the weld point. Does anyone know where a Repro or NOS one can be obtained from?

Thanks in advance!

John, those cheap chrome dual feed Holley lines were not original equiptment on any Chevelle, as far as I know. There should be a 3 line set-up, with a fuel block between the two small lines going to the carb. Ground up sells it all. Here's a shot of mine.

Bill,

I am the original owner of my 1970, LS-6, and it did come with that fuel line in the pic that I posted (the engine in the pic is not mine, and it's been the first time I've seen that fuel line since I removed mine).

It leaked so bad at the fuel block, I had to replace it with neoprene, fuel inlets and clamps. Unfortunately, I removed it back in 1970 and have no idea where it is, since I moved several times since.

I'll check with Ground Up as you indicated. Thanks! :thumbsup:

Nice "Fleet" BTW! :yes:

The factory-installed fuel line is all inverted flare fittings, you can see them in Bill's photo at the carb inlets and at the block under the PCV hose. No weld points.

I agree with the rest of um, that Mr Gasket chrome fuel line didn't come from the factory.
Replace it with the correct stuff that Bill has on that beautiful engine. Check with Ground Up for the lines. Much safer than rubber and hose clamps on the pump side.

Well, if it didn't come from the Factory, where did it come from? I never replaced it until it began to leak. As I stated, I am the ORIGINAL owner of my car. I ordered it, waited awhile for it to be assembled, paid for it and drove it home. Only one other person has driven it other myself, since I've owned it, for the past 38+ years.

Okay, it may NOT have been a weld, but where the two lines exited the fuel block, they appeared to be brazed together before they branched off to go into they respective fuel bowls.

I agree that the fuel line is a lot safer then neoprene, but it's held up for a very long time without incident. However, since I'm replacing many of the engine parts with repo or NOS parts, I thought I would attempt to return that fuel line to it's factory equivelent. Had it come with a fuel line similar to Bill's, why would I replace it with neoprene instead of a NOS replacement at that time?


Thanks!

If you want a chrome one like you have on there, Summit, Autozone, Jegs, or just about any autoparts store has them hanging with the header gaskets and aftermarket chrome tid bits. You will need to know the distance between the fuel inlets since they come in a couple different lenghts. Summit has it listed as SUM-G3100 for $15.95 to fit a Holley 4150 double pumper. Now what is a factory Chevy part doing in a Summit catalog?? 8^)

Hey John,

Don't know if you have an AIM for your car, but if ya don't you might pick one up. In there there is a wealth of info including the factory setup for your fuel connections. As the guys mentioned above, the line your are describing is aftermarket. You will not see any mention of it in the factory assembly manual. Although, you can get the part you describe still. If you'd like to go back to the old stock style, there are all kinds of vendors that sell the factory setup in both steel and stainless steel. It's a bit more for the stainless.

Good luck on the restore!

John;

For an original `70 LS6 with the factory low-rise intake, the fuel line is as shown below:

The image Bill posted above is the correct line for a factory high-rise intake, which is different from the low-rise set.

Be advised that while several vendors offer a reprouction line in stainless steel as well as mild, the stainless lines are notoriously difficult to get to seal up properly. I strongly advise going with the mild steel lines.

Hope that helps.
Eric

Thanks, much Bro's! :thumbsup::yes:




Eric,
I have the Factory, low-rise intake. (You restored my carb Eric, and it's the Holley 4557, what's the cfm of that carb)?

You're welcome, John.

Based on stories and other reports I've heard from former GM employees, when a vehicle was delivered to a dealership from the factory back then, there were times that it was vandalized while sitting on the lot.

My SS was delivered on a Tuesday and I picked it up on the following Friday, in late February, 1970. Now, had some thieves stolen the original fuel line in the interim, the possibility exists that the dealership may, and I emphasize the use of the word may, had gone to a parts store, purchased and installed that chrome aftermarket fuel line on the car. The possibility also exists that the original line was defective. It's also possible that the original wasn't in stock and since they were aware of my pick-up day, they had no recourse to repair it so it would run. They also could have gone to the nearest GM plant located in the same City, and could have obtained it there, but the problem was that the GM plant in Linden, NJ did not assemble Chevelles. My car is a product of the Baltimore, MD, plant. I know, I know, a lot of "possibilities" and "may's," but I have no other explanations. :clonk:

There was no reason, nor did I have the time (I was recovering from battlefield wounds and was still employed by the US Government, to wit, the U.S. Marine Corps), to go tinkering with something that already was installed and working fine. I NEVER made any swapping out of any of the other original parts with the exception of the wheels, tires, exhaust manifolds and the Muncie shifter (throughout the later years), all of which I still have in my possession. Hence, I have no other plausible reason why that chrome fuel line came with the car when I picked it up. I NEVER, EVER installed that aftermarket line on my car; I only REMOVED it due to the leak.

Other then what I stated above, I have absolutely no idea why my car had that chrome fuel line on it. :clonk:

Now that I've read all the input and have seen pics contributed by the good members here, I have some type of guide to locate the correct line.:hurray:

Thanks everyone! :thumbsup:

No worries there, John. Weird things do happen all the time. You've got some pretty knowledgeable folks here. I've learned a bunch from 'em and continue to! You really can't go wrong with the AIM for most items either. Hang in there....and ask away when things don't seem right. It's gonna be a nice car when you're done!

John;

I thought that might've been your carb.

The 4557 is rated at 780 cfm, although some refer to it as an 800; both figures have been published by various sources over the years.

Thanks Eric...I forgot to ask you that question over the phone when we spoke last.

BTW, WE couldn't be happier with the excellent work you performed on my carb. What a difference! :yes: :hurray: My Wife, the one responsible for packing it, loved it! :thumbsup: She was also impressed when I informed her what you told me about the packaging, when I shipped it to you and says, "Thank You."
