Fuel System

The fuel system is pretty much complete from firewall back. You will notice the new Andair fuel boost pump, this pump is very compact and easy to install. We need this as the engine is fuel injected.

We are using the Newton fuel selector valve, I really like the feel of this selector, it has a ceramic bushing inside and the movement is very smooth. The left and right are reversed for our application so I machined off the original markings and engraved new ones.

I secured most of the fuel lines by wrapping a piece of 1/2 x 3/8 in tygon tubing around the line and then attaching to fuselage tubing with white hockey tape. Where it is hard to wrap tape I use nylon waxed lacing, again around a piece of tygon tube. A good deal of these areas get covered in fabric.

The gascolator will have An3 bolts holding it on with lockwired heads.

A bit tight but they will not touch.

Very easy to plumb.

Nice and compact!
