[Tigers] Balance pipe nipple thread

[tim]

Listers,

 

The parts book calls for a 1/2" UNF tube with a compression sleeve where the
fuel line meets the balance pipe. I went through this with my Alpine and as
I recall, the 1/2" UNF tube nut worked fine.

 

The balance pipe I have for the Tiger seems to have a different thread. My
local supplier was stumped and said it almost looks like a Whitworth thread.

 

Does anybody have insight into this? I bought the pipe on EBay as the
original was trashed so it possibly came from a different model? I guess I
could cut the nipple off and weld on a new one or find a different pipe
altogether but I am still puzzled by this.

 

Thanks,

Tim
