Now check the bottom of the fuel cap.
Dirt and sand that collect around the filler neck can keep the cap from screwing
on properly. That can bend the metal lip inside the fuel tank opening which, in turn,
damages the gasket on the underside of the fuel cap.
Make sure you brush or blow away any dirt and sand before opening the fuel cap.
Then, make sure the filler neck area is completely clean before closing the fuel cap.
Inside
Before screwing the fuel cap back in place, pull out
and check the fuel strainer inside the filler neck.
If the strainer is clogged with sediment, clean it
thoroughly with dry cleaning solvent. Then inspect the
strainer for any cuts or tears.
M113-Series FOV…
Don’t
Forget Fuel Cap PM
Topside
Some of you may forget that there’s a screen cap and
rubber vent grommet on top of the fuel cap. If it’s not
cleaned every 6 months—more often in dusty, sandy
environments—the cap gets plugged with dirt. That cre-
ates a vacuum and causes fuel flow problems.
Here’s how to inspect and clean the cap and grommet:
1.
Grip the tang in the center of the fuel cap with a pair of
pliers and pull the screen cap out.
2.
Eyeball the grommet in the
fuel cap. If it’s damaged,
replace the entire fuel cap.
3.
Clean the screen cap with
dry cleaning solvent.
