Fuel Pump Failure Fix
Fuel pumps run when the master
switch is ON. But sometimes you want
the master switch on, but you don't
want the pumps to run.
Here's a simpLe way to shut t±e pump
of and save them ²om earLy deaths.
Get anD instalL the NATO sLave recep-
tacle parts kit, NSN 2590³01³201´
7858. The µuel pumps wilL no longer be
on the same circuit as the master switch.
The pumps won't run as much, so they
will last longer.
CompLete instalLation and wiring instructions come with the kit, anD plenty o¶ the
kits are on hand. Your CO can authorize you to get the kits and install them. Then
you'll start saving µuel pumps.
