Fuel Tank Leak?

[JoeRuscito]

That was also my original thinking! I will call to clarify once again...

Putting it on both threads sounds very bad to me; you will just push it off the female threads into the system-not good at all. Those instructions I believe are for when you use it to seal two flange surfaces. I would NEVER NEVER do that on a fuel fitting...

...from the factory... "Yes we are using the new sealant and yes you should be fine.. You installed according to the directions.

You will get sealant residual in the system and therefore a good practice is to clean the inline filters after about 10 hours of operation… Also be sure to sump the header tank.. especially the first fuel runs.. "

WOW is all I can say to that! Out of curiosity what brand is this new blue goo? Likely solvent based if it needs to sit open. If so, some are not compatible with alcohol (ethanol). I'd do some research.

YMMV, Greg

This is the blue goo in question:

It does state that it is resistant to ethanol.

This blue stuff needs to go.... used the same stuff on my brake fittings and now those are leaking.

I think Im going to redo every fitting on the plane with the re branded 9AR stuff "Permatex 9AR was re-branded Permatex Tack & Seal Gasket Sealant Item # 80938"

So any ideas on good ways to clean the blue stuff off. It leaves quite the mess?

Would someone describe what the banjo fittings are or show a picture of these. I'm not familiar with this term.
