TANK ADAPTOR 3/8-1/4 BSA

This is a tank adaptor, a threaded fitting used where a fuel line connects to a tank or petcock, stepping the pipe size down from 3/8 to 1/4. The catalog entry marks it as a BSA-thread fitting, so check what's threaded into your tank before ordering. We don't have more detail on this one beyond that description, so give us a call if you want to confirm it against what's on your bike.
