f you want to keep your Bradley’s FUEL FILTER CLOGGED light off, you’ll
have to pay close attention to your fuel filter PMCS, drivers.
The -10-1 TMs say to drain water
after
every operation. If you forget, the sepa-
rator starts to rust. The rust and water mix with contaminants in the fuel to create a
gloppy buildup that can plug the bottom of the separator.
As fuel flow lessens, the Bradley’s engine begins to sputter and jerk. On comes
that FUEL FILTER CLOGGED light.
Things can get even worse in cold weather. Water buildup freezes into a solid plug
that stops fuel flow completely. It can also crack the separator as the ice expands and
contracts.
Changing the filter won’t fix the
problem, either. Once the damage is
done, the only fix is to have your
mechanic remove and clean the sepa-
rator with a mixture of water and
liquid detergent, NSN 7390-00-990-
7391.
So, drain the filters after each oper-
ation into a clear container until clean
fuel comes out. Then make sure you
dispose of the fuel in an approved haz-
ardous waste container.

Stryker…
F
uel flow on the Stryker can be a little tricky, drivers.
Fuel is supposed to auto-
matically transfer from the
right to the left fuel tank as
fuel is burned. But sometimes
the pressure relief valves
stick on the left and right fuel
tank caps, especially if they
get clogged with dirt or sand.
That can create a vacuum
that allows the left tank to
empty while the right tank
stays full.
When that happens, it’s up
to you to relieve the pressure
so fuel will transfer properly.
You do that by opening the
left and right fuel tank caps
every 4-5 hours of operation
to relieve the pressure.
