FUEL TANK SERVICE

TC Type II/TM engines have fuel tanks with an integral fuel
screen and integral outlet fuel fitting. Integral screens or
fittings are not serviceable (diag. 3-19). Some TC Type I
engine models use a pressed in fuel filter or a weighted filter
and a flexible fuel line in the tank. Pressed in fuel filters and
fittings can be serviced using the following procedure (diag.
3-20).
1. Press the fuel fitting into the tank and feed the fuel line
in until the filter can be removed through the filler
neck. Remove the filter and fuel line if necessary.
2. To install a new filter and fuel line: Cut the end of the
fuel line at approximately a 20° angle to make
installation of the fuel line through the hole in the fuel
tank easier. Push the new fuel line through the tank
outlet until the fuel line protrudes through the filler
neck. Cut the angled portion from the fuel line.
3. On tanks without weighted filters, push a new filter on
the fuel line. For weighted filters, slide the new
retaining ring on the fuel line protruding from the filler
neck. Push the fitting into the line to the fitting
shoulder. Slide the retaining ring over the groove in
the fitting and crimp the retaining ring using a pliers.
4. Attach the fuel line and weighted fuel filter if applicable.
Pull the fuel line through the tank outlet. The filter barb
or the fuel fitting barb must protrude from the tank.
