P-80 is pumping fuel into the gas line
Hi,
My P-80 is pumping fuel into the gas line when running...? Does this engine have a common line inside for the fuel and the starting gas?
I'm using pure butane for starting gas, which has a pretty low vapour pressure at low ambient temperatures: could this be the cause?

Hello,
Sorry for the late reply I am in China on business.
Yes the 2 fuel rails are linked. The cause of the backflow is a leaking gas solenoid valve. If the valve is leaking and not the lines or fittings going to the valve, then you really need a new valve.
Hope that helps,

Put a manual shutoff valve in line with the gas solenoid, and shut it off after start if you don't want to replace the valve. Bob
