Installed the fuel line from Vans and it sits on top of the left exhaust. No clearance at all. Have been trying to find a 45 degree elbow (maybe a 90???)from the carb connection to Van's fuel line? Any ideas? The connector from the carb has two different sized ends? The one end does match the hose supplied from Vans. The other end screws into the carb screen fliter? Help?
