Fuel System

Fuel System


The fuel system is one of the most important systems in an aircraft. I have been using 100LL mixed at 50:1 with Penzoil 2 cycle oil. I opted not to install the oil injection system. The kit comes with a 10 gallon tank which is OK, but the pickup tube was a short fuel line which came into the top of the tank and had a fishing weight attached to keep in on the bottom. Plus the tank was installed with the filler forward behind the passenger seat, so it is almost impossible to fill. So first I installed a proper finger strainer in the bottom of the fuel tank sump and plumbed it to a proper aircraft approved gascolator for water seperation and a drain. Water in the fuel is one of the essential things to check for a safe flight. I also moved the tank sideways so the filler is facing the side of the aircraft easy filling.
Fuel tank mounted properly to the side for easy filling.
	FAA approved gascolator with bottom drain. As you can see the tank has a sump built in so I had to do a little changing to the frame.
Here is the view of the auxiliary fuel pump. Should the Rotax vacuum pump fail this pump will keep the engine running. It is recommended to turn the pump on during take off and landing. You can also see the top of the gascolator.
	Mounted forward of the aux pump is the manual fuel shut off ball valve .
The fuel system also includes an engine primer mounted up under the throttle. The primer lines are all aluminum tubing, because I did not want to run plastic hose through the passenger compartment.
