KAWASAKI ULTRA 310X Clogged

Fuel Injector

The injector's internal solenoid-operated pintle becomes fouled by varnish and gum deposits typical of phase-separated ethanol fuel in marine environments. In supercharged applications like the 310X, these deposits restrict the spray pattern and flow rate, leading to significant power loss or lean misfire. Replacement is the standard engineering resolution because the internal micro-filters are difficult to flush once polymerized fuel has set.

Fuel Pump Strainer (Tea Bag Filter)

This is the primary filtration stage located within the fuel tank. If this mesh becomes saturated with debris or begins to degrade, it allows particulates to reach the injectors or restricts fuel volume to the rail, mimicking a clogged injector symptom. Replacing this ensures that new injectors are not immediately fouled by upstream contamination.

Fuel Injector O-Ring Set

The thermal cycles of the supercharged 1.5L engine cause the viton seals on the injectors to harden over time. When removing injectors to address a clog, these seals must be replaced to maintain the high-pressure seal required for the fuel rail (approx 43-50 PSI) and prevent vacuum leaks or fire hazards.
