Fuel Line Problems

Is it possible to tighten the blue connection too tight? I wasn't getting fuel with a new pump. I had the plugs out and put the intake hose into a can of gas (to ensure it wasn't a fuel line or tank problem) and was getting lots of fuel as expected. I noticed a little fuel dripping from the new pump so I tightened up the connections. I put the plugs back in and connected to the fuel line - no fuel. Put the intake hose back in the gas can - no fuel.

I believe that tightening up the connection is the only thing different....

I doubt that tightening the connector could cause the problem. Where are you checking to see if you are getting fuel out of the pump? At the carb or connection to the carb? If so, do you have a fuel filter between the pump and carb? I'm wondering if the new pump is working all the time or if it isn't installed correctly; i.e., its arm on the cam.

While there are torque specs on those fittings, I also doubt that's your issue. Most vacuum gauges are also fuel pressure testers. Hook it up to the line and see if you have fuel pressure. Inspect all the rubber lines from the fuel pump back.
