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.
