I'm doing a little maintenance on the bike and want to be able to run the engine while the tank is off the bike so I purchased a 4' long fuel line to run to the carb from the tank. The 3/4" fuel line is all that I attached (not the reserve or breather line). I made sure that the tank was elevated and that their was no dip in the fuel line to the carb. Well it didn't work, in fact when I took the line off there was no fuel so to test my theory further I pulled the fuel line off all together and opened the peacock and still nothing. What's the deal? Does the breather line pressurize the tank and force fuel through the line or do I have something blocking the peacock inside the tank? Any ideas\suggestions?
