Tee fitting on gauge leaking

[015point9]

 

My push on tee fitting is leaking at the stem going to fuel gauge, very little but enough I should fix.  Wrapped with Teflon tape maybe 4 or 5 wraps.   

Buy another fitting or is JB Weld alright to use in diesel fuel?

I would get some permatex thread sealant and ditch the tape. As I know the permatex is good with diesel fuel. If over tightened the aluminum or brass tee can crack, check for that also. 

Permatex diesel safe

You can also use Rectorseal No5.    I keep a can of this in my work van and use it on a variety of applications.  You can get it at the Home Dept.

I have used this stuff to assemble my air compressor black water pipe lines. Happy to say no air leaks. Stays pliable for a long time.

I used self-sealing brass fittings no sealants needed.
