AP .09 engine

[Guest]

I have an AP .09 engine that I purchased off of ebay, when delivered it has muffler sticking out of back. It had a fitting in the bag(came of muffler) that looks like a fuel fitting. Someone tell me what this is so I can find a new 1. PLEASE help!!!lease:

Hi again Dennis,it sounds like a fitting to pressurise the fuel tank. Using fuel tubing

you connect from the fitting on the muffler to the fuel tank,this uses the muffler

pressure to pressurise the tank to keep constant fuel feed. This isn't always needed

it is used mainly for flying aerobatic types,or if the fuel tank is in a less than perfect

position. Regards John
