One of my new LJ taps had a tendency to leak - I discovered that the contaminants in my tank (very fine metal filings!) must have been getting between the viton seal and the tap body. I ended up fitting the longer reserve taps anyway and lnow that the filings are gone the eaks have disappeared, but it's worth pulling your tap apart (very simple job) and cleaning it all up. The leak only manifested itself when the fuel hose was removed, so somehow leaking past the 'off' position - which also means that the tap wasn't really 'off' when parked.

You would have been buggered if it was one of those riveted jobbies.
 
Triumph motorcycles from 1983 to 1988 have Italian fuel tanks and use the same fuel taps as a Laverda.

They are usually much cheaper than buying the same fuel tap from a Italian motorcycle dealer.

The first job with them was to drill out the rivets and tap them for small screws. On mine the rivets weren't even piened over properly and the plate was loose. Shit quality but worked ok with screws.
 
Neighbour ladies across the road - their mower was leaking fuel from the air filter. Good samaritan me had a look - found the prob ... non-ethanol 91, fresh fuel. But like our mower, there's no fuel tap so when not in use the fuel just sits in the line and the float bowl. No idea how this much rust managed to grow in there!

I’m not a great fan of snake oil, generally speaking, and I know this isn’t a snake oil thread, but about 30 years ago I started using Pro-Ma PT5 with 91 octane in the Jota and Mercs. These share fairly high compression and supposedly need more octane. However, works out cheaper, fuel doesn’t go off and systems stay dry and rust free. And we don’t have Moas ‘cos some dudes liked the feathers …
