I want to install a brass fitting in a poly gas tank and thought I would use teflon tape as a sealant for the threads on a barbed hose fitting.. Amy better ideas? Fitting seem a little loose. Thanks in advance for your reply. Jim ________________________________ Message 2 _____________________________________ Time: 01:14:03 PM PST US Subject: Zenith-List: Re: Teflon Tape & Auto Gas From: "chris Sinfield" Teflon tape is not recommended as it blocks up the fuel filter when it breaks up. People have used it on external areas but I would not recommend it on any fuel lines. Chris.

If you ever reuse the fittings, there is a risk of the shreds of teflon tape getting into the lines and clogging things up. A small amount of white teflon paste or something like Permatex Aviation Form-A-Gasket would be a better choice.

Use it and you won't have any leaks (especially use it with brass fittings). Some people use it incorrectly, and it sheds and gets caught in the fuel filter, that's true, But than again anything can be misused I guess. When you apply it, make sure you wrap it in such a way that when you screw the treads in it will tighten the Teflon and not unwrap it (this causes the shedding) Also, don't wrap the last 2 threads, that will keep it from extruding out of the threaded area.

Keep it level length wise and get the angle right. Fixture the position. At that point I had two tables and made both right and left skins at the same time. That way I only had to layout one and pilot drill through two sheets. Having the structure set right next to the skins layout table made transferring the measurements to the skins easy. I know you have limited space but you could lean a couple sheets of plywood against a wall, and cleco the two aluminum sheets to the plywood for the layout and pilot drilling of the skins. Think lean to, or a-frame. -------- Ron Lendon, Clinton Township, MI WW Corvair with Roy's Garage 5th bearing Zodiac XL, ScrapBuilder ;-) http://www.mykitlog.com/rlendon Corvair Engine Prints: http://home.comcast.net/~rlendon/site/ Read this topic online here: http://forums.matronics.com/viewtopic.php?p=232537#232537 ________________________________ Message 12 ____________________________________ Time: 07:37:10 PM PST US From: "Roger & Lina Hill" Subject: RE: Zenith-List: Teflon Tape & Auto Gas Jay and Others; Yes, when removing existing fittings, always check for contamination from Teflon, dirt, and shredded rubber (if you're using barbed fittings on natural rubber hoses). It's always best to flush the line, fuel or otherwise, after doing any work which might introduce contamination into the lines. Fuel filters should be checked (or preferable changed) every 3 months or 50 hours of operation. Having more than one fuel filter is of course acceptable. I have 3. One in the gassolator, one before the carb inlet and one built into the carb inlet (a finger strainer). Also, I have one in the main tank, though it's a screen really.
