We mounted our fuel dot filler to the left front of the fuselage. For
a fueler mount, we cut and scabbed in a small piece of 1/8" lite-ply.
This was drilled to accept the threaded aluminum fuel filler
receptacle and held in place with the nut that came with the filler
system.
The Tygon overflow fuel line was routed forward and out of the
bottom of the secondary firewall. We used a small plastic clamp,
screwed in place to the secondary firewall to hold the overflow line,
pointed straight down.
We mounted our fuel tank on the left tank mount platform. We cut
a piece of 1/4" foam rubber to fit onto the plywood mounting pad
and then secured the tank firmly in place using a single piece of
1/2" wide two-sided Velcro.
Throttle Servo Installation:
Now that the engine and fuel tank are installed, the throttle servo
can be installed into the fuselage.
Because of the very large
amount of area within the fuselage, the throttle servo can
realistically be mounted just about anywhere. However, we always
prefer to keep all radio equipment, including the servos well away
from the forward mounted ignition module, ignition battery pack
and related wiring. For this reason, we like to mount our throttle

The kit fuel tank also includes two small nylon cable ties. We used
one of these over the rubber stopper, pulling it tight to secure the
stopper firmly in place to the tank. The remaining cable tie can be
used to hold the carb and overflow lines together, as they route
forward to the front of the fuselage (if you are like us, you will want
to use more of these cable ties to organize the fuel tubing and
servo extensions.

bend in the
aluminum tubing overflow line, allowing it to reach the inside top of
the tank body. We suggest chamfering the top of this tubing to
keep it from touching and possibly closing off on the inside of the
tank. Use a second piece of aluminum tubing, straight through
the rubber stopper, for the carburetor and tank "clunk" line
connections. Attach the provided Tygon fuel pick-up line with the
weighted "clunk" in place. Slide the end of the tubing onto the
straight piece of aluminum tubing on the backside of the stopper.
Insert this assembly into the tank neck and firmly press the
stopper over the molded tank neck rib. Use a flashlight to make
sure the angled aluminum overflow tube is centered at the top of
the tank. Once the tank is complete, use one of the included nylon
cable ties around the rubber stopper to lock it firmly in place to the
tank neck. The fuel tank is now complete and ready for installation.
Fuel Tank Installation:
The fuel tank is now installed in the fuselage.
Start by first
arranging the required "plumbing". If you are using a simple 2-line
fuel system, as we did, then this becomes relatively easy. From
the fuel tank aluminum carburetor/clunk line, you will need a length
of Tygon fuel tubing to route forward to the "T" fitting for the fuel dot
filler system. From the other side of the "T" fitting, attach a fuel line
that will go directly to the carburetor. From the third nipple on the
"T" fitting, a length of fuel line is attached to go to the fuel dot filler
system (the J'Tec #F2 Gas EZ Fueler is shown). Be sure to leave
enough fuel line from the "T" fitting to the fuel cap to allow about
5" or so of tubing to be pulled out of the fuselage for fueling and
de-fueling. Note the use of 4" cable ties used to organize the fuel
lines.
