Guess the repair..

Am I the only one that has used a fine-cut chain saw file to slightly open up the passage for the larger O.D. high-pressure fuel line? Does not require the removal of too much aluminum to create an airtight yet easier to service pass through.

With an almost total absence of carburetors on both 4-wheelers and motorcycles, there are fewer sources for the thinner-walled, low pressure fuel hose. Just another joy of owning classic -and now near vintage class- BMWs.

I have no problem getting regular fuel line at either a chain type auto parts store, or NAPA .
