 Posted: Wed Sep 18, 2013 10:25 am Post subject: Airworld fuel gauge sealing - what to use |
 |
|
I fitted the airworld fuel gauge a while back and when the tank is up to the top of the tube it seeps at the screw heads and round the top of the tank. I spoke to airworld and they said to take each screw out and apply some automotive gasket compound. I brought some fuel resistant hylotyte from hylomar. Has anyone had a similar experience? The design seems bound to fail as the fuel is surely going to seep through the threads. Also tightening is going to just crush the poly tank.

Graeme - I have not yet tested the fuel-tightness of my tank, but I did pressurise it as much as my lungs would allow while observing for bubbles in washing-up liquid wiped around the likely areas of escape (old bicycle tube puncture finding technique). I had sealed around my Mod 60 tank probe with Loctite 5922, which I got from Grampian Fasteners. It was recommended to me by Brian Fogg, who said that smearing it around the flange of the sender had cured the cockpit fuel smell he'd had for a long time. He got his from Halfords, but my local branch never seemed to be able to get any in stock.
Hope this helps.

Roqland
use Hylomar Blue, Rolls Royce use it on their engines so it must be good.
Should find it locally.

Just be aware that any excess compound may get into the fuel system and
could result in a filter blockage.
We used a silicone gasket sealant to seal the fuel float gauge on my
previous kit aircraft (Shadow) and it broke off into the fuel forming
perfect jelly like spheres which blocked the fuel line. Engine stopped at
2,000 ft - fortunately we were within gliding range of the field.
I appreciate Hylomar is different (ie: not silicone) but needs to be used
sparingly. I have used Red Hermetite to seal fuel connections in the past
and it will form a fuel proof seal.

Hi! All/Graham,/Roland
Fuel system sealant.
Yes, Graham is right , Hylomar is a product made under licence from Rolls Royce who developed it, I worked there and it was mandatory . However it only requires a very thin but positive film, no globules should be allowed to be ingested into the live fuel system and definitely allow 10 minutes for the solvent to evapourate before assembly of the flanges/ threads. Had some taken out by my mini Andair gascolator filter mesh and wondered what it was for a while.

I don't know what you are screwing into but on my fuel gauge set up I have
sealed anchor nuts on the tank side. Basically it is a standard anchor nut
with a plastic(?) fuel proof cover over the nut. Got the nuts from LAS.
