I Have an old M30 REDDY HEATER, It won't start, Good Spark, Good Fan, Clean fuel, Pump has some pressure- I have no-idea on how much is needed, Not sure about the in-out of fuel lines to the Main Jet (M29681), One line comes from pump and other from fuel tank, can blow air into fuel line and hear some bubbling going on in tank. Can't find a diagram of fuel lines. HELP PLEASE

The line from the pump to the nozzel should go inthe front fitting and the one from the tank goes to the backfitting. If either of these have cracks in them or do not fit tightly over the fittings it will not build enough pressure and burn. You may also check the filters mainly the output filter as this will also effect pump pressure. I don't have as much experiance with that brand so I can't be sure exactly about the pressure. I think it should be 3.5 to 4 Psi. If this doesn't help please email me and I will find out for sure.
