problem with jetcat p60se

Please help.
We have some problem with our jetcat p60se. The propane start is fine. The priming the fuel to the engine is fine but once we stop priming the fuel. The fuel slowly go back to the tank. Once the propane starts. The turbine e seems to pull fuel away from the fuel line. The fuel is going backward to the fuel tank and not the turbine.

Anyone know what might be the problem. The p60se is brand new.

Thanks for your help in advance.

I have one of these engines & have no problems whatsoever, just started straight out of the box. Check how you have everything plugged into the ECU, the servo type lead connections are a bit confusing.

My ECU is the larger V6.0 unit.

With the side of the ECU with the assembly screws visible you can see 6 pins which stick out from the case marked on the ECU label - Airspeed/Propane. The gas solenoid plugs onto the lower pins with the brown wire to the right.

On the other end of the ECU the ECU label is marked Smoker/Fuel above 6 pins. The fuel solenoid plugs onto the lower pins with the brown wire to the right.

Directly to the right of those the label is marked Thr-Ch/Aux-Ch above another 6 pins. Your throttle lead from the receiver plugs onto the upper pins, signal wire to the left, positive wire in the middle & negative wire to the right.

Hope that's a help. John.

Sounds like you have a large air leak in one of the hoses, fittings, pump, or valves.

I would start by taking all the fittings/hoses apart... verify they are clean, and cut straight... and then reassemble.
