How to Increase Gas Flow to an Outboard Engine
- 1). Check the fuel filter. The fuel filter helps keep the fuel that is delivered to the engine clean. If it is dirty, then clean the fuel filter. Replace the filter if necessary. If the filter is dirty, fuel flow can be adversely impacted and obstructed. A clean fuel filter ensures that gas is flowing to the engine through the filter as fast as it can to the outboard engine.
- 2). Clean the fuel tubes. Over time the fuel hose that delivers fuel to the engine can become clogged with sediment. Clean the fuel hose or replace it. Sediment and debris on the walls of the fuel tube make the tube smaller. If the tube is smaller, less gas can flow through it. Less gas flowing through means that the engine is not getting the fuel it needs. Cleaning these tubes will increase gas flow to the outboard engine.
- 3). Upgrade the fuel pump. A performance fuel pump can deliver more fuel to the engine quicker than a standard fuel pump can. The upgraded fuel pump will deliver more gas to the engine. A fuel pump is essential to gas flow, being what moves the gas from the fuel tank to the engine. A fuel pump is perhaps the most important component for increasing gas flow to the engine. A performance fuel pump for the outboard engine can increase gas flow and performance.
- 4). Use the highest octane fuel recommended by the manufacturer. High octane fuel burns cleaner and quicker. Higher octane fuel in an outboard engine is burned faster. Since the fuel is burned faster, more fuel is needed to replace what has been burnt. The faster the fuel is burnt, the faster the gas flow is in the outboard engine.
