Re: teflon tape ?
Teflon tape was only invented beacause:
Teflon tape was invented to replace petroleum product types of sealers when used on gasses and liquides that have a serious dislike for oil products. Like liquid oxygen.
Teflon tape when installed wrong can do the following
1. Break aluminum castings (such as fuel filter housing, fuel pumps, etc.
2. Too much Tef Tape and you can insulate the threads from the base metal which will make the sending units non-sending units.
3. To much Tef Tape will cause them to leak.
4. To little or wrong way of wraping will cause leaks.
5. Taping over the end a little will have loose tape going into the sender, or fuel system or whatever you are using it on.
Since about 90% of the poeple I have watched install the stuff, have done it wrong, So, why would anyone recommend it's use.
The ONLY good thing about it, is it doesn't leak in your tool box or get your fingers messy. It sure has nothing to do with sealing a pipe thread joint.
PS: Neither Merc, nor Volvo recommend it. And in a few manuals, it has a warning specifically saying NOT to use it.
So why do you guys like it so much??????????? Doesn't make any sense to me.
