TITAN X-340 - FUEL SYSTEM - FUSELAGE
IMPORTANT:The header tank is designed to fit on the left side of the
cockpit. Changing this location will affect the design of the system and is
NOT recommended. The weight of the fuel and header tank is low and
close to centerline and does not impact wings level rigging.
1. Locate Header Tank Mount per FIGURE 11-08/TITAN340. Transfer drill #30
through each tab. Glue Rubber Edging to top edge of Mount flanges. Rivet
Header Tank Mount to top of tabs.
HEADER TANK ASSEMBLY
1. Locate and drill fitting holes in Header Tank per FIGURE 11-09/TITAN340. Do
NOT drill the sump drain holes until fitting of the tank to the fuselage. For drilling
the holes a 1/2" Unit-Bit®and 3/4" Unit-Bit® work best. Locate center of each
hole with a #30 drill bit, then drill full size. Deburr all holes. Thoroughly clean
tank several times by rinsing with water. After confirming that all foreign material
has been removed, let dry prior to installing fittings.
NOTE: If it is anticipated that the plane will be converted between Trike
and Taildragger, then it is recommended to install sump drains in both
locations.
DOUBLE & TRIPLE CHECK HOLE LOCATIONS BEFORE DRILLING.
2. To install the fuel fittings into the tank, obtain a piece of wire. Safety wire works
well. Insert wire through one of the fitting holes in the tank and up through the
filler neck. Refer to FIGURE 11-10/TITAN340. Install an O-Ring onto the tank
withdrawal fitting and slide this assembly over the wire extending from the filler
neck. Bend a loop in the end of the wire to keep the fitting and O-Ring from
falling off. Pull the fitting through the hole. Slide a flat rubber washer, thick steel
washer, and a retaining nut over the wire and onto the fitting. Apply Loctite to
threads and thread the nut on before removing the wire.
CAUTION: Do NOT get Loctite on the rubber washer.
3. Use an Allen wrench inserted into the tank fitting to hold the fitting while
tightening the retaining nut.
IMPORTANT: Do not allow the fitting or thick washer to rotate while
tightening or leaks may occur.
HINT: Prevent the thick washer from turning by holding with needle-nose
Vise-Grips.

4. Apply thread sealant to fittings and install into the tank fittings. Again, allow no
rotation of the tank fitting. Refer to the parts manual for the correct parts.
5. Perform a leak test by capping off all fittings and pressurizing the tank to 1 PSI
and let set for a period of time.
CAUTION: Damage may result from over-pressurization. While the tank is
pressurized, check for any leaks by spraying a soap/water mixture onto
the tank and around the fittings. To cap off the fittings use a 1" segment of
fuel line with a bolt inserted, and fuel line clamps or similar. An alternate
test is to fill the tank with water and let it sit for approximately 48 hours.
6. Modify Header Tank Mount Channel per FIGURE 11-11/TITAN340. Position
Header Tank flush with front of Mount. Use large hose clamps to secure tank to
mount.
NOTE: Modified Mount Channel will position under hose clamps, on top of
tank, and be positioned so that Channel ends are flush with sides of
header tank.
7. Drill a #40 hole in edge of Fuel Cap. Screw on the cap and tighten. Using the
hole in the cap, safety wire the cap against rotation to the fuselage frame.
(AFTER WINGS MOUNTED TO FUSELAGE)
8. After wings are mounted to fuselage in final assembly, route fuel line from each
wing, down behind Station 3 and to Header tank. Secure as desired using plastic
ties. Add a clear plastic tape or split fuel hose as anti-chafe wherever the lines
contact the fuselage frame or other parts.
LOCATING HEADER TANK SUMP VALVE HOLE THROUGH BELLY SKIN
1. Mark on the outside of the tank on each side next to the sump valve as per
FIGURE 11-12/TITAN340. This allows location of the hole through belly skin with
the tank installed.
2. Set the header tank in place. Transfer the marks on the tank to the belly skin.
Remove the tank and project the marked lines at 90° to the sides of the tank until
they intersect.
3. Drill a #40 in the skin at the intersection. Set the header tank securely in place.
Drill #30 through the hole in the skin and the header tank. Use a step drill or
several sizes of drill bits to work up to the required size hole for the sump drain
fitting.
