Thinking more about Roland's problem, I wonder whether he could have had a
damaged
end with the inner part seperated from the outer, which allowed a flap to
get pushed in when forcing the hose on to the connector, partially blocking the
lumen, only allowing adequate fuel flow for small throttle openings, and having
no route for a fuel leak to make things obvious. A burst of full throttle
might push the flap a bit further in or simply use up the fuel in the carb
bowls.It
is easy to imagine that further handling of the pipe could then produce
a full thickness split. David Joyce
