Fuel System Primer; Fuel Filters - BRP Evinrude Installation Manual

Fuel System Primer

Outboards require a priming system to refill the
fuel system after periods of non-use. The most
common priming system is a primer bulb in the
fuel supply hose.
Install the primer bulb as follows:
•
The primer bulb must meet the same Fuel Flow
Requirements as the fuel hose.
•
The primer bulb should be easily accessible.
•
The arrow on the primer bulb must point in the
direction of fuel flow.
•
The fuel supply hose must allow the primer bulb
to be held with the arrow pointing up during
priming.

An alternative to a primer bulb is a U.S. Coast
Guard approved marine primer pump. Electric
primer pumps offer the convenience of outboard
priming from a dash-mounted momentary switch.

Fuel Filters

Boat-mounted fuel filters and water-separating
fuel filter assemblies must meet the required fuel
flow and filter specification. Refer to Fuel Flow
Requirements.
FUEL SYSTEM REQUIREMENTS
The filter must be mounted to a rigid surface
above the full level of the fuel tank and accessible
for servicing.
Fuel Filter Assembly, P/N 174176, meets all
requirements for a water-separating fuel filter.

Avoid using in-line fuel filters exter-

characteristics may not be adequate for high
horsepower outboards.
