For anyone that has the original, on-off, fuel valve, and might be thinking of changing to a newer style valve, here’s a brief overview of my installation of the Andair, left-both-right valve.
The project required replacing the fuel lines between the two header tanks and the fuel filter as well as fabricating a small box to house the new fuel valve. I had the seat pans out for the annual already.
Fortunately, I had lots of practice on my Glasair I with a Subaru engine. The fuel system required a full return system. I bent tons of tubing and flares prior to this project and it was great practice. As a result, each of these seven new GlaStar lines were bent pretty close to perfect on my first try.
I’m not trying to brag, just showing that I paid my dues with plenty of bad bends and junked tube in the past.
Total time to complete the following work was 12 hours:
- Laminating a second low-point drain mount pad
- Draining the fuel tanks
- Removing the old fuel lines and valve
- Installing the second low-point drain
- Fabricating the new lines
- Fabricating the box to mount the fuel valve in
- Installing the valve
- Testing fuel system
- Painting the valve box
- Reinstalling the interior
