Brass petrol tap seizeing up

[Jeff Blight]

Hi any one got a fix for a quite new fuel tap getting rather tight it’s the brass lever type and I’m haveing 
To use pliers to move it !

[Ivor Hawkins]

If it is the brass taper type, I find lapping the taper with some Brasso helps, not only sealing, but aids smoother operation.

Dismantle and smear taper with Gold Hermatite.

Jeff, the one on my chummy is getting to that point. I plan doing what Ivor suggests, though I will also lubricate with graphite flake when I reassemble.

Brasso is also not what it was, Autosol or Peek is now my preferred brass lapping compound. Sometimes I use 'Pink' bought from B&M it is a compound sold to housewives for cleaning around the house. Its coarser than Autosol or Peek.

Do not lap with any form of carborundum, valve grinding paste etc it will embed in the brass and you will get nowhere.

Someone recommended a small quantity of two stroke oil, added to the petrol. I never tried it but replaced the tap with a PTFE/Ball valve seated one, designed for a motor bike.

I had to remove the filter but you could make an adapter to house it.

I agree these are the real long term solution.

+1 for that tap. Fitted one on the Chummy and completely eliminated any leak... plus it has very smooth operation..

When they get tired and weapy just lap them in with timesaver compound. Its good on allsorts of things and unlike most lapping compounds it does not imbed into the surfaces of the metals been lapped. I have used it on plastic, brass, gunmetal and white metal with great results.
