Tap Thread Type and size

[rbt11548]

Can anyone please tell me the thread size and type for the Petrol/Gas tap to tank connection?
Thank You.

= 1/4" BSP (or 1/4" Gas).

As it's a pipe thread, the *1/4"* doesn't refer to the actual thread diameter: http://www.britishfasteners.com/threads/bsp.html

Thank you, I thought it was 1/4" pipe but wasn't too sure and needed it confirmed. I am going to put new taps in.

The best taps (ie no leaks when off) are the BAP taps as fitted to the late Coop Triumphs, not original but the pattern copies are not the best. The BAPs should be available at the Lanark Autojumble on 1st Feb at one of the Triumph stalls.

Thanks for that, are you saying go for the originals and NOT the copies?

There are the orginals, copies and BAP's. The orginals are not available so go for the BAPs, I would go for BAP's even if the orginals available. I have 20 year old BAP's on mine and they are going fine, just the zinc plating has discoloured.

Ok thanks!

Just take one of your old fuel taps and cut a few lines across the threads with your die grinder or hack saw and then run them in and out a few times. That should clean up the threads good enough if thats what your trying to accomplish and its not going to cost $20 for a BSP tap?

Ya here's what they looks like, the two on the left. http://www.oldbritts.com/13_604512.html

The BAPs are just as bad. The brass repros are OK if you take them apart (snap ring) and lube the rubber with silicone grease every year. I don't mind doing this yearly maintenance for the price they go for.

If you want some really good ones try:

I have not tried them because they are so darn expensive but others have and like them.
