If you have a Caterpillar
diesel engine, you may
have this spin

on filter
and fuel separator/heater.
It is mounted in the engine
compartment on the

It has a metal drain bowl at the bottom. Occasionally,
check the bowl for any water or particles. To check or
drain the bowl, shut off the engine. Then push up on
