Gasoline is extremely flammable and highly explosive under
certain conditions. The fuel system consists of fuel lines, fuel
filter, fuel pump, and an unused fuel recovery system. Fuel in the
system is under pressure and must be relieved before servicing.
Because of the inherent danger of fuel leakage into the bilge,
do not attempt servicing or maintaining components of the fuel
system.
Your Indmar dealer has factory trained technicians and U.S. Coast
Guard approved marine grade parts required for fuel systems.
Your Indmar engine may be equipped with a spin-on type water-
separating fuel filter that needs to be replaced every 100 hours or
annually, whichever occurs first.
!
WARNING
The fuel filter is under pressure. The pressure
must be relieved before removing the filter.
Removal Procedure (Safety Glasses Required)
1. Disconnect the negative cable from the battery or place the
battery switch in the OFF position. If the boat has more than
one battery, disconnect all of the negative cables.
2. Remove the cap from the Schrader valve at the top of the filter
head.
3. Use a fuel system pressure tester which will capture the fuel
and allow it to be drained into a suitable container.
4. Use an appropriate filter removal tool or strap wrench to turn
the filter counterclockwise to loosen.
