I've searched and the combination of "vent" and "tube" pulls up discussions of everything from fork tubes to crankcase vents, but not this question specifically.
On the nipple under the fuel tank of my 1981 R65, there is a short elbow of what used to be rubber meant to connect the overflow tube to the tank nipple.
It fits both OVER the vent tube, and OVER the tank nipple, so its original ID was the other's OD.
Itss become quite hardened and will no longer fit-up to the tank nipple.
I've also been unable to ID this little part from fisches at Max, Bobs and lookups at Boxer2valve.
Has anyone found a replacement for this part?
Or, have you replaced the vent/overflow tube with a larger ID and just ran it straight to the tank nipple?
Or, something else?
