Fuel Tank Sealing

[facthunter]

Silver solder blind nuts to the bottom plate and just use a gasket or suitable "O" ring. Any silastic etc you use is likely to cause a problem. It's no different to the fuel Gauge  float type arrangement that goes in car fuel tanks.. Tank sealant is usually where the tank has rivets somewhere, like the Mooney's wet wing I mentioned. You need good access to the insides to apply the right stuff to them.  Nev

The one you referrence in your comment yesterday.  Also called "Aviation Soft Seal No3".  Meaning non-hardening compared to No 2.

Does this mean that, in your opinion, all of the other sealers mentioned,  will work?

[Thruster88]

For your application, mostly mechanical seal and on top of tank an automotive product will be fine.

I Ian,

 

Yes its great stuff, reminiscent (same smell and tackiness??) as most of the pre silicon sealants. I  have had the same tube of STAG in my plumbing tool box for possibly 8- 10 years - used sparingly works a treat. You think it would work around the studs on a flange mounting, as depicted previously??

Yeah , I have tubes in various stages of use for donkies !  I use it on all tube/hose fittings including fuel sender to tank seals , and mine are side mounted......no leaky...nicee.

If I get a chance i'll see if I can get a pic under the dash of one installation.

just a quick (remote_ under dash ) pic of a sender in the horizontal wall of a 60 L header .

 

screws pre smeared before insertion !
