4. PERFORMING A TEST

The following is general information describing how
to setup and run a test and generate a test report. For
specific step-by-step procedures for the D3241 test,
see the D3241 Manual.

4.1 INSPECTION OF COMPONENTS

Inspect all O-rings and seals for cuts, abrasions, and
excessive swelling and replace as necessary. Inspect
the insulators and replace if they are cracked,
chipped, or otherwise damaged. Inspect all stainless
steel components for damage and replace as neces-
sary.
The inside surface of the fuel reservoir must be free
of scratches. Hold the clean, dry reservoir up to a
light and look through it to detect any scratches.
Inspect the lip seal for nicks and cuts; do not remove
the seal from the piston. When lip seal replacement is
required, check the mating surface on the piston for
scratches.
CAUTION - The lip seal is made of soft virgin
Teflon and is easily damaged.

4.2 CLEANING

All components containing test fuel must be clean
and free of contaminants. Place a new piece of
aluminum foil about 450mm square or larger on the
bench for placing all test section components after
cleaning. Use a wash bottle filled with solvent (N-
Heptane or Iso-Octane) to flush all components.
Position a cleaning pan to catch the solvent during the
cleaning operations. Wear protective gloves because
of the possibility of skin irritation from solvents.
JFTOT II Operation Manual Rev. C
WARNING: These solvents will irritate the skin
after a short time. Use rubber gloves. It is
recommended that gloves not be reused. The
solvent is flammable and harmful if inhaled.
See Appendix A1
Flush the following components with solvent:
• reservoir O-rings
• filter/aeration funnel
• glass jar
• glass aeration tube
• insulators
• heater tube housing nuts
Flush with solvent then use a squeeze bulb to blow
out the following components:
• all fuel lines
• pre-filter components
Attach a quick-connect fitting to the bottom of the
water reservoir. Flush the inside surfaces of the
reservoir and cover with solvent. Using a squeeze
bulb, blow out the fittings to remove solvent. Remove
the quick-connect fitting from the water reservoir
when dry.
Flush the inside surfaces of the fuel reservoir and
cover with solvent while scrubbing with a nylon
brush. Then flush the inside surfaces with solvent
without brushing. Using a squeeze bulb, blow out the
fitting to remove solvent. Holding the fuel reservoir
piston by a piston puller, flush all surfaces of the
piston with solvent. Then scrub the piston with a
nylon brush, being careful not to brush or damage the
lip seal. Then flush the piston with solvent. Do not
remove the lip seal from the piston.
CAUTION - do not nick or scratch the lip seal.
The lip seal is made of soft virgin Teflon and is
easily damaged.
Using a nylon brush saturated with Trisolvent, brush
the inside surfaces of the heater tube housing. This is
the only component that requires cleaning with
trisolvent.
