I might have to replace the oil pressure gauge line on my 67 327-350. The line that runs from the gauge to the top rear of the block. Is this line still available anywhere? I can't seem to find it in my Corvette catalogs (ZIP, LICS, etc). Also, is it possible to replace the line without removing the dash cluster? Thanks.

Re: Oil Line
You'll find the line listed in Paragon's catalog (as well as others) as # 1132K at a whooping $6. I wouldn't advise replacing the line without pulling the instrument cluster (at least loosening and shifting forward a tad) unless you're a REALLY small guy.... -
Re: Oil Line
You can also probably pick up a replacement line at an auto parts store, but it will be plastic/nylon. It will function fine but not look original. Do NOT substitute copper tubing. It will work harden and fail in short order.Comment

Appearances can be deceiving. Try a magnet on it. It should be copper plated steel if it is the original.Comment

Appearances can be deceiving, Mario
The original line is copper plated STEEL. We've had a number of discussions about this, and there are claims that copper tubing replacements are being sold on the aftermarket as "restoration parts."
Copper tubing is a very poor material for fluid lines in any kind in vehicle becasue it work hardens from vibration, becomes brittle, and can eventually break.
A magnet will quickly tell you if the line is the correct copper plated steel. A suitable replacement line will stick to a magnet. If the line is non-magnetic it should absolutely not be used.

Re: Oil Line
Mario:
I recently replaced the copper line on my '65. The ONLY place I could find a copper plated STEEL line, as original, is L.I.Corvette supply. If originality is not a concern, then substitute with a steel line, as mentioned in the above posts.

Re: Oil Line
I just replaced the oil pressure line on my 66. It was not that difficult to reach with the cluster in, except the parking brke was in the way. The kit I got from Ecklers came with a copper tube, although their catalog said otherwise. Can the steel line required be obtained a local auto parts stroe or hardware store? Or am I going to have to order a whole new kit? Thanks, DanComment

The Paragon oil pressure gauge lines are the correct copper-plated steel material also.Comment

Re: Oil Line
Mario, I do believe you can make the change without touching the cluster. I have been able to do it quite easily on my 67. In fact when replacing my cluster I connected the oil line last after all was in. I also just replaced my oil line without touching the cluster. Just used a small mirror and small wrench. If need be you can squeeze in under the steering wheel and use direct vision, if your eyes can focus anymore. Note, I am not small, 6'4" 225, go for it!

Re: Thanks Everyone
Mario,
I bought a line for my 63 from LICS last year and it was copper!
Returned it and got the correct copper plated steel line from Paragon.

Re: Thanks Everyone
The other thing to watch out for (on my 68 anyway) is the type of compression fitting used for the fitting at the guage. Many generic aftermarket kits use a ring style compression fitting that will slide all the way in to the guage fitting and then the nut will not swege down on the ring. It will go back together but it will not hold oil. The correct one (again on my 68) has a conical shaped compression fitting that nestles near the top of the guage fitting allowing the nut to press down on it.
It sounds like if you go Paragon you won't have a problem.

Amendment
In checking my receipts, I found that I purchased the copper plated steel line from PARAGON, not L.I.Corvette. I must apologize for any confusion that may have arisen from the incorrect vendor that I named in the above post. I made a lot of phone calls, and Paragon was the only parts house (I contacted that offers the correct line.

Re: Oil Line
Dan:
Paragon (not L.I. Corvette) has the correct line for $6.00. I know, you will pay more in shipping than the cost of the part (we should all buy stock in Fed Ex).
I never tried the hardware store or plumbing supply house, but I suppose it might be worth a try. They MIGHT have unplated steel capillary tubing (which will work fine if you are not going for cosmetics)
