Fuel Tank Valve

[windsmaker]

Got a Beneteau First 38 1983 with fuel leak at the on/off value to the tank.
The brass fuel tank valve is labled " LB " ..." ??" connects to the fuel line with a leaking compression fitting to a 3/8" copper line. .
Can't find a compression nut for this valve anywhere !!. (I think it is 8mm ?? )
I believe it is metric.. w fine threads.
Anyone know where I can find the compression nut for this valve ?

Old stuff is hard to find parts for.

If it's the suplly side of the tank, just replace it with a length of hose, supported here and there. If it's the return side, take the fitting off and take it around to a truck parts outlet or an RV/bus parts place. They can probably match it.
