Teflon Tape on oil & fuel lines

I know this might be a dumb question but I am in process of replacing fuel tank and sending unit and oil cooler hoses. Is it a good idea to use teflon tape on the male connections?
It's 80 degrees here in central PA and I've really got the bug to get out. Just about done so any help or advice would be greatly appreciated.

Re: Teflon Tape on oil & fuel lines

The seal on those lines is at the flared ends where they meet, metal-to-metal. T-tape is likely only gonna keep the fittings' threads from binding/rusting. Aught to do with sealing the fitting. A ~SMALL~ amount of anti-seize on the threads would be better, IMO.

Don't use it. If you must, use a tiny dab of the white paste/dope or the silver antisieze paste; wont seal it, but will make removal easier as Doc suggests.

If it is going to leak, it will leak, and the tape won't help you. I had a bad oil cooler hose that teflon tape would not seal (machining imperfection on the mating surface); Moss sent a new one for free and it sealed up fine with no "sealant".

Had a similar issue with a brake line that almost sent me to the rubber room.
 
Go for the white teflon paste before you use any tape type stuff I've seen the tape stuff get caught in all kinds of places that caused blockages that were not fun to get out
 
Not on an MGB but, I had a flared line once that wouldn't seal. It was a 2000+ lb line on a piece of construction equipment. We were out away from the shop and the place to get a new line was closed to Monday. It was Friday evening. An old mechanic of mine, God bless old mechanics, took the line off, cleaned the flared end and then tinned it with solder. A microscopic film of solder. Put the line back on and it never leaked again. The thin film of solder created a seal. He got the machine running and back on the job which ended Sunday noon. Needles to say, he got a bonus for that one! Don't know for sure, but I think the line is still on the machine. Amazing what some old time ingenuity will do.
 
Good'n Paul! Me Granfar was a millwright... he tinned the ends of about everything he'd assemble. I though he was nuts until I had a hairline split in a bubble flare end and tried it in desparation. It got me home... but I changed it ASAP.
 
There are also annealed copper flare inserts available to mend bodged sealing surfaces on lines and fittings. Inexpensive, and very effective, in their proper place.

NOT on a race car YOU drive, I'd hope! /bcforum/images/%%GRAEMLIN_URL%%/devilgrin.gif

mehheh... so you did Sir, so you did. /bcforum/images/%%GRAEMLIN_URL%%/laugh.gif
 
I've always used Fuel-Lube/Ez-Turn on aircraft oil/fuel fittings. It's thick and sticky as can be, but does the trick to load up the threads and lube the fittings. The 5oz Tube will last forever.
