Another little problem Last weekend the bike ran great and didn't miss a beat. However there was a slight smell of fuel when parked up. Went out to use it this morning and found a small pool of petrol on the garage floor. I have drained the tank but no time to deal with it as I am flying out tomorrow The suspect is either the fuel pump gasket or a cracked weld. Anyone know where I can buy the gasket as I would like to build up small selection of easily replaceable parts. I checked with Thiele on their website and though they have gaskets they didn't list the full pump. Anyone know where I can purchase another. TIA

Are you sure it’s not the red plastic fuel connection elbow?
Hi Voodooo. The tank was partiallly removed the previous week so could be. I will take it apart next weekend and advise. Thanks for the input.

Check the plastic 90° outlet and also check the O-rings in the fuel line fitting.
 
My alloy fuel tank was leaking at the welding seam several times.
Norton has changed the fuel tank and a half year later was the new one also leaking.

Do you recall who makes the aluminum fitting?

Nice , Like to find that source .
Well it looks like our friends City Garage and Coote’s know where they come from lol.

Looks like a small hole needs to be drilled and tapped. Seems nice and way better than plastic.

Looks hand made . Or I mean looks like a one off somebody made .
 
Can't a replacement be sourced from Moto Guzzi?
I thought the pump assembly is same as used by a MG model?
