ater in your grader, loader, scraper, excavator, or dozer’s fuel system is the biggest
cause of clogged fuel filters and ruined injectors.
Actually, nearly all fuel con-
tains some water. Condensation
adds more moisture to closed fuel
systems.
So what can you do to stop the
damage? You can help keep water
out of the fuel systems on com-
mercial construction equipment
with an in-tank water absorber.
The absorber works like a
weasel in a hen house—it doesn’t
come out until it’s full! It comes
in two parts: a plastic sleeve or
guard, and a cartridge.
The absorber is available in
different sizes:

M917A1 Dump Truck…
T
here’s no doubt that cold weather can cause the dump truck’s tailgate and materi-
al control system (MCS) to move slowly.
But before you point a finger at Mother Nature, make sure the air tank for the tail-
gate and material control system is drained.
This tank is seldom drained because it’s in the back of the dump truck under the
tailgate’s cover. But when the temperature drops, condensation gets into the air lines
and solenoid-controlled air cylinders.
During operation, that condensation causes the tailgate to become sluggish or to
lock up. Dumping operations come to a halt because the tailgate won’t open or
close.
So before you call it a day, pull the air tank pull cable to let any water out. Release
the pull cable when all the water and air have drained out. This procedure is Step 16
of the operator’s PMCS in TM 5-3805-264-14&P.
One pull…
