[Healeys] fuel line

[BJ8Healeys]

Hi, Alan -

I don't know about the chemistry, but the diff and gearbox drain plugs are,
I believe, a pipe thread.  That may make a difference.  I still use the
PTFE/Teflon tape on those, too, and haven't had a problem with leaks or
weeping -- at least to where it's a problem.  As long as it doesn't leave
spots on the floor, I don't worry about it.

Guys.
The chemists among you may be able to comment on my observations.  In an
attempt to deal with the last few niggly oil leaks on my BJ8 I used PTFE (is
that what you call Teflon?) tape on the threads of the diff plugs and
gearbox drain plugs.  It appeared to work for a while but then mysteriously
the slight weeps down the threads returned.

On investigation it appeared that the tape was dissolving in the mineral
oil. Does that sound feasible?

Hylomar did the trick instead.

Regards..........

I guess that easiest way to look at the tape, no-tape issue is if the tube
joint has a flared connection (including compression fitting) or not. There
is
no reason to use tape on a flared fitting as the fluid seal is at the flare
not  the threads. Actually having to much tape on the threads of a flared
fitting may  keep the fitting from exerting adequate pressure on the back
side of
the flare.  Sloppy home made flares also cause a bunch of problems.
