Sounds like the plane has already been set up. We were using PPM for a very long time before PCM or 2.4 ever came along so no real problems there, just keep everything as far away from the engine as you can. I just buy things like alcohol or acetone in one gallon cans and save them, they have the bigger cap on them. I just make up my own lid with two brass tubes soldered into it for the pick up and out flow. The only difference between a six shooter for gas is the tube inside the pump, they sell a kit for both gas or glow. I just use a hand crank glow pump for mine, nothing inside the pump that gas attacks. Tygon gas line is a must. Not a lot in the way of field equipment needed. Think of it as just another brush cutter. If you go into the gas engine forum you can get a lot more detailed information if you need it.
