Once the tanks are back together, they should be leak checked before installation in the
aircraft. Connect extra lengths of fuel tubing to the fuel and vent lines and submerge the
tank in water. Pinch off one line and gently pressurize the tank by blowing into the other,
looking for signs of air bubbles. If the tank shows evidence of air leakage around the vent
cap, tighten the Philips head screw and check again. If you have a stubborn leak, you can
re-tap the inner plate for a slightly larger 6/32 cap head bolt.
Step 3: Tank Installation

•
Re-attach the Tygon tubing to the main saddle tanks. Make sure the lines are of equal
length. Exercise care not to break the tanks while fitting the Tygon. Slowly wiggle the tubing
into place. Wire tie for security.
•
Insert the saddle tanks into position. They should be a fairly tight fit. Here I have used a clear
silicon or you can use goo to secure in place.
•
As photo 1 shows, the tanks fit in nice and tight.
You will need to make a centre tank support from scrap ply to for the front of the tank to make the
tank level this should be fitted once only once the air intake has been installed. This tank needs to
slide to the rear of the fuse with the rear of the tank at the front of the engine hatch. As detaukled
in Photo 1
•
It also needs to incline slightly from rear to front to insure adequate clearance for the
engine hatch.
•
Temporarily position the lower engine bypass on the mounting rails. I have had to modify
the bypass to account for the rotation of the main wheels. You can modify the bypass as I
have to maintain a by-pass flow in conjunction with the main undercarriage housing.
•
This will also assist in the stabilisation of the trust tube and help to centre this with the thrust
line of the engine.
•
Do not slip and secure the intake extension into place until you have finalised the nose
wheel installation.
THIS STEP IS MOST IMPORTANT
•
Connect all three fuel tanks together. As I prefer to run my fuel tanks in series when using
multiple tanks, the sequence of filling of tanks is as follows:
