If sediment is present it will generally be located
in the bottom of the fuel tank. It is possible that
sediment can also accumulate in the fuel rail.
Sediment from the fuel will collect at the bottom
of the beaker if a fuel sample is allowed to settle
for a few minutes.
Fuel Quality - Excessive Ethanol
Excessive concentrations of ethanol may cause
driveability conditions. According to EPA guidelines,
non-blended normal gasoline may contain up to
10% ethanol. It is acceptable for the J-44175-A
tester to indicate up to 15% ethanol (65 Hz) for
non-blended normalgasoline.
IMPORTANT: The accuracy and reliability of this
entire procedure depends on preventing the fuel
sample or the tester's fuel sampling cell from
becoming contaminated.
Clean the 100mL beaker with a clean, dry paper
towel before taking a fuel sample. DO NOT USE
compressed "shop air" to blow out the beaker.
Compressed shop air often contains water or solid
contaminants. Contaminants of ethanol -blended
fuels include water, methanol, and salts. Be careful
not to allow fingerprints, sweat, water or any other
outside debris to contaminate the fuel sample,
beaker, tester or fuel gage as this will cause an
error in the test result, leading to a misdiagnosis.
TWO fuel samples are to be taken, with different
tests on each sample. Fill the100mL beaker to the
100mL mark on the beaker for each sample.
