I am in the process of restoring my gas tank and have got into the quandry of where to stop. This leads me to my question regarding replacing gas lines on my 69 L36 convertible. The current lines have what appears to be surface corrosion. So, should I just try to clean them with some steel wool or replace them? If I replace them what would be the point deduction for going with stainless steel lines? Is this component judged/checked? I may want to get the car judged one day, but also want to prepare if for the perverbal "long-haul" and upgrade components where possible (i.e. won't effect my potential point total). I have stated on the many posts that everyone has helped me with that I am new (6 months) to all this, and am still learning/trying to figure out how best to do things. I don't want to commit an unforgiveable NCRS sin by upgrading to SS gas lines if that is if fact what it is consider to be. As aways thanks!

SS gas line flares if not perfect are very hard
to get to seal into the brass fittings. if you use SS one use a steel fitting to "set" the flare before trying to get it to "set" in the brass ones -
Re: Steel vs SS Gas Lines?
Dwayne
The lines are easy to replace when the body is off and very hard to do with the body on but a few have done the job. I would clean the outside for now. As for judging they will be checked and SS is a deduction. I would replace them with standard lines if I had the body off and the way a 69 is used by most they will last much better than the original set of lines.

Deduction for SS items...
is in the NCRS Judging Reference Manual, Section 4, Rule 11. It's a matrix that reads this way regarding the loss of originality points for the use of SS where non-SS components were factory installed:
(1) All misc items, deduct 50%
(2) SS fuel lines, deduct 50%
(3) SS brake fluid lines, deduct 50%
(4) SS exhaust pipes, deduct 50%
(5) SS mufflers, deduct 60%
(6) SS exhaust pipes AND mufflers, deduct 75%Comment

SS Gas Lines are not an 'upgrade'
The original TBW lines lasted from 1969 to 2006 with only external corrosion to show. If you replace them with TBW, these will last probably twice as long considering the reduced usage of the car. By the time these new lines are worn out the car will be over 100 years old, and probably you too.
What would you gain with SS?Comment

Re: SS Gas Lines are not an 'upgrade'
Mike, you got! I agree with analysis and logic completely. I can't understand what the fascination is with SS lines.
Exactly what advantage do people think they are going to achive by using them?BobComment

Re: SS Gas Lines are not an 'upgrade'
Bob and Dwayne-----
The main advantage of stainless steel lines is, of course, that they don't corrode----from the outside OR the INSIDE. Sometimes, the latter can be pretty important for brake lines.
I'm a "stainless steel guy"; I like stainless steel better than gold or silver. HOWEVER, I do not recommend it for fuel or brake lines. It is just too hard and "non-conforming" of a material to get a reliable seal at flared connections. Plus, the value of the corrosion resistance over TBW lines is not nearly enough to "offset" the above-referenced problems.In Appreciation of John HinckleyComment

Re: SS Gas Lines are not an 'upgrade'
All,
Thank you for the advice and sanity check. I'll first try to clean up what i've got. If that does work out I'll replace with steel.Comment

Re: SS Gas Lines are not an 'upgrade'
Joe, Why not use for fuel? There is no flares on iy. I like the SS for fuel. MikeComment

Yes, for the frame line only, there's no disadvantage to using stainless. I was pretty much referring to the other fuel lines, most of which do have flared fittings.In Appreciation of John HinckleyComment

No disadvantage to SS chassis fuel lines unless one is having their car judged.TerryComment
