1 — Drain Valve
CAUTION!

Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appropriate
container.

Do not prefill the fuel filter when installing a
new fuel filter. There is a possibility debris
could be introduced into the fuel filter during
this action. It is best to install the filter dry and
allow the in-tank lift pump to prime the fuel
system.
WARNING!
Do not open the high pressure fuel system with
the engine running. Engine operation causes
high fuel pressure. High pressure fuel spray can
cause serious injury or death.
