MAIN FUEL TANK INSTALLATION

.....

 Once installed, the main fuel tank also serves as a support for 

the legs of the pilot and passenger. The geometry of the tank was, 

therefore, laid out to provide not only fuel volume, but also 

adequate support. 

.....

A fuel drain valve must first be installed in the bottom 

fuselage at the approximate low point of the fuel as part of the 

normal preflight checklist. 

.....

Begin by locating FS45 at BLOO. Draw a 2" diameter circle around 

that point and contour a depression in the center of the circle that 

is 111 square and results in a foam thickness of 1/4". A toothpick is 

useful for gauging depth. Make a smooth transition around the area. 

.....

Bond in with Flox the 1" x 1" X 1/4" mild steel plate and then 

laminate 2 BID over the entire depression overlapping a minimum of 1" 

onto the inside bottom fuselage skin. Once that lamination has cured, 

make a 'dome' from some aluminum screen door screen that covers about 

a 2.5" diameter circle, and attach the dome to the bottom fuselage 

over the depression with flox all around the perimeter. 

.....

From underneath the fuselage, tap a 1/8" NPT hole into the mild 

steel plate for the fuel drain valve, which then may be inserted and 

tightened. 

.....

 Finally, find a piece of Versa tube Aluminum tubing of 1/4" 

O.D. and 20" in length and locate it as shown. The tubing pierces the 

aluminum screen and points forward, being affixed with liberal 

quantities of flox at the junction with the screen. Be careful not to 

flex the tubing unnecessarily to prevent fatigue of the tubing.
