8N gas leak and teflon tape

I have a gas leak that did not seem bad until I filled the tank Sunday. I shut the fuel valve off at the sediment bowl after using the tractor, but there is still a leak that seems to be coming from up around the threaded area where the filter screws into the tank (the threads stay wet).

Would it make sense to drain the tank and remove the filter, cover the threads with teflon tape and reinstall? Anything else I can try?

Thanks again!

They now have a teflon tape that is fuel and natural gas rated. Get the yellow tape.

I still prefer good ol' rectum, er, rector seal for natural gas lines. But I think that's because I've got 4 or 5 cans of the stuff laying around I haven't used up yet. :)

I do maintenance on gas pump systems for service stations.All replacement hose fittings/nozzle assys are marked/tagged"do not use teflon tape".I don't know if its the "shedding" effect or incompatability w/fuels. I use paste pipe dope rated for fuels/steam etc.....just for info

Duke,
If you use teflon tape on any fuel lines start wrapping it about 2 or 3 threads back from the end. If any of the tape should happen to get loose it make a good plug at filters or needles and seats. I have had good luck with diesel lines wrapping them with tape and then using pipe dope.
When you tighten the fitting, DONT back it off any or it will surely will leak. Also with all that tape and dope you have to be careful you don't overtighten. Easy to do with that much slick stuff.

I worked in a refinery years back. They would not use teflon tape on their instrument lines because small pieces of the tape would come loose and plug up the instruments. They used pipe dope. You might have the same problems with the tape plugging up carb jets, etc.

My $.02 worth,
Danny

teflon tape didn't do it for me
Plumber's pipe dope did

your mileage may vary

Duke, As long as the threads aren't messed and the flare and seat is in good shape, teflon tape should fix the leak...just make sure to cover all the threads...

"Seal-all" applied over the leak might be a temp fix....DaBrow

I agree , "Seal All" will fix any gas leak instantly,even if leaking when applying.

"Seal-all" sounds great. Where do I get it at, and how do I apply it?

Cheers!

Just squeeze a little on the spot where it is leaking. I've used it on a motorcycle tank that dripped approx. one drip every 3 to 5 seconds.
Stopped instantly, I kept the motorcycle about 8 months and never again leaked while I owned it. On the tractor that I used to own, a Ford 801 the tank turn on valve was worn beyond repair, here in Vancouver Canada, the FNH dealer wanted approximately $100.00 for a new one that had to be ordered in, I went home and applyed Seal All on and it sealed instanly, the valve no longer worked but I replaced it with an automotive shut-off valve for $7.00.
