Could someone suggest a source on NOS or repop C1 Oil pressure lines with correct tubing outside dia and weatherhead fittings? Thank you.

Re: C1 oil pressure line
There is no source of correct dia. lines except the junkyard. The same dia line was used on many medium and heavy trucks of the era. The problem with this line, is that it is so small in I.D. that they are prone to clogging.
The repro lines will quite often pass judging without notice, but the fittings will not. The judges have become so used to just checking the fitting size to determine originality, that quite often the line will not even draw any attention. You can take the repro fittings which have 3/8" flats on them and grind down the flats to make the fitting 5/16". This is really a pretty easy job and will not take more than a few minutes with a dremel tool or small die grinder equipped with a small sanding disk, and the finished product will be just like the original. Also, contrary to what the JG says, the line was not copper plated. This was a midyear finish, and all the C1 lines were tinned steel and should look silver to dull grey.

Re: C1 oil pressure line
I sincerely apologize, but I can spot the oversize OD of the oil pressure line from 10 feet away. On the other hand, maybe I won't be judging the oil pressure line on your car. In any case, John's approach is probably worth a try. The difference in correct/incorrect lines is 1/32"... Best, DennisComment

Re: C1 oil pressure line
I have doctored the weathereads in the past as John suggests and it does work out quite well, however, I also agree with Dennis that even though only a diff of .100 vs .125 OD that the diff is glaring. Just seems to me that with the hobby where it is today that someone would have stepped up and done this thing right as size does matter and they all have one. Regards,JoelComment

Re: C1 oil pressure line
Dennis,
I too can spot them from far away, as I am sure many judges can, but I have had very good luck with getting them by judges once the fitting was modified. I think that maybe a lot of the newer judges have never seen anything but copper-plated, Repro lines and think that this is the correct configuration. LOL
In any case, you can be assured in getting a deduct for the 3/8" wrench flats on the fitting, while modifying it to 5/16" will take one more point off the table if you can't find an original.
