New fuel tank

Should there be any kind of material between the fuel tank and body? Silicone, etc.

I used strip caulk.  Not sure if it is what was used originally.

I used the black strip caulk by 3M.
Worked great.

I bought the black 3M stuff. There is a bake lite or plastic piece that I think holds the fuel sender wire. It’s kind twisted from muffler heat. Does anybody make those or do I make something to hold the wire?

Not all 67 Shelby's or SJ produced Mustangs used that strip type clip to hold the wire. Yes it gets distorted by the transverse muffler heat. The other style individual clips used to hold the wire are typically more prevalent and are reproduced . It is not known why some cars used one type of clip and others used a different.This a Mustang thing and not a Shelby issue. Ether style is acceptable however a heat distorted strip clip would be seen as a negative vs. a non distorted shorter individual single clips version in concours competition.

There were two styles of wire retainer used for the fuel sender in 1967 and 1968 model year. One style is a metal clip, the other style is a plastic sheath about 6" long. Sounds like you have the plastic sheath. Both styles are available at WCCC in used original parts.

I did check WCCC and they sell used. They are currently out but they show what I have. Thanks for all the help. Might need more. We shall see.

Don't use the new 3M strip caulk, it is a nasty/sticky butyl-based material.  Look for 'rope caulk', which I believe Eastwood and some other places sell.

I used the 3M product about 4 years ago for tank installation. Charles is correct, it can be a sticky mess. Temperature is important, too warm it's sticky-gooy, but too cold it can be hard to work. If you proceed with using it because you already have it experiment with finding the best temperature. You may not find any temperature you like. If you are not satisfied toss it out and follow Charles' advice.

I guess this is one of those good news / bad news things for me. I bought way too much of it about 4 years ago. Will need to find a new source whenever I run out. Does PPG still sell it in the caulking gun tubes?

Pictures of the original sealant after an original tank was removed

See you have a May 17th finished example. Don't see the sheath often at all on 67 San Jose cars. Not sure why they were used other than possibly a test. 1968's with them are really rare to find also. We've done a survey of the retainers for all three plants for 68 production over on CMF But only a very small number have been found on 67's

Looking at pictures I see a couple of other examples with them also but have not cross referenced the Ford VINs to see if I can find more in that range as far as Mustangs go

The vast IMHO majority of cars were supplied with the typical rubber dipped metal clips attached to the fuel tank opening lip as shown below



Fuel tank sealant is a gray in this picture due to air and sun exposure over the years of sitting in a yard ;)

Sorry don't have a clear 67 strip/sheave picture handy only 68's. Will look
