Hi,
I have a 75 Avion built on a 74 chassis.
The fuel line from the fuel pump to the carburetor has a hose connecting 2
sections of the line. There are about 2 inches of space between the 2 ends,
the ends look like they are factory cuts rather than someone just cut 2
inches out of the line. I have been told there should not be any hose after
the pump.
I parked in my driveway 4 days ago with the front wheels about 8 inches
higher than the back wheels.
The engine has taken several seconds to start if it has not run for a day
or 2.
When I took the line apart I was surprised there was no fuel leakage. There
is a clear fuel filter at the pump input with just a little fuel in it.
What should keep the fuel from running back into the tank so the fuel pump
does not have to charge the line?
Did the 74 units come with a solid line from the pump to the carburetor?
One good thing is the oil pump has time to lube the engine before it starts
