I recently had to replace the freq. valve because line to valve sprung a leak at both ends of fuel line @ the tip of connector to the banjo fitting. I also just sprang leak at the cold start valve on the fuel line at tip of connect of banjo. Is this the valves causing these lines to break/leak or is this the results of a problem at the fuel dist. or fuel pressure regulator? i dont want to have to go around the horn breaking fuel lines if theyre arent the problem.
