Stripped threads in carburetor
 

I have a 1981 F-150 with 302 motor and automatic transmission. Bought it a
few months ago from a guy whose condo association made him get rid of it.

The fuel filter is the sort that screws into the carburetor. While
replacing it I managed to damage the threads in the carburetor inlet.

What I'm looking for is an inexpensive way to fix the problem, preferably
without removing the carburetor from the vehicle. I don't want to spend a
lot of money on this. The carburetor itself is working OK and I don't want
to replace it if I don't have to. As is the motor will run fine, but there
is a leak from the carb inlet due to the threads being stripped.

Thanks for any suggestions you can offer.

Go to Lowe's. Buy a roll of teflon tape, used to seal pipe joints to
prevent leaks. Carefully replace the filter, after winding the tape on the
male threads in the direction such that it tightens the end rather than
loosen it when you screw the filter back in. HTH & good luck, s

Teflon tape is 'not' a sealant, it is only a lubricant allowing you to
tighten a fitting easier and tighter. It will not work on stripped
threads.

Loctite 'might' work if it get a chance to cure before use or a helicoil
thread replacement can work.

sorry but wrong. teflon tape is not a lub it is a sealant. it is
developed specificily for pipe threads and is made to seal the thread in
a liquid fitting. use enough wraps and it can sometimes crutch up and
seal buggered up threads if your carefull. it is worth a try. KB

For *water* pipes, yes. The result when you attempt a halfassed "fix"
like wrapping teflon tape around stripped threads in a *water* pipe is
that you have a flood.

The result when you attempt a halfassed "fix" like wrapping teflon tape
around stripped threads in a *gasoline* pipe is you have a fire. Gasoline
dissolves teflon tape in short order.

To the original poster: there are repair fittings available that are
slightly oversized. They cut new threads in the carb body as you thread
them in. NAPA Echlin 2-75, see he

I am a plumber..... I have 'never' seen or heard of teflon tape fixing
anything. It only allows you to tighten the fitting tighter so the real
sealing faces have a chance to stay tight.

If liquid is getting down the threads, nothing in my plumbers box short
of solder will hold it.

Threads are not sealing points.

He needs to be able to get the threads tight enough to have the washer
seal the faces of the fitting. Teflon tape will only help finish the
stripping job.

I like that idea less than teflon tape. I had a piece of brass fitting
end up in my carb last year and jam the float open... not a pretty sight.

(It was my own damn fault trying to thread a pipe thread into a flare
fitting at 2am instead of calling it a day...)

Thank you for the advice. I will get the repair fitting. Have been
unsuccessful with teflon tape on ordinary water pipe fittings in the past,
and certainly would not want to risk it with a carburetor.

That makes you vs. the rest of the world, which has zero problem with
these repair fittings when they are installed properly.
