How does a gravity fed fuel system work?
Gravity feed fuel systems use a fuel tank placed above the carburetor to use gravity to deliver the fuel. The fuel tank must have an atmospheric vent to prevent a vacuum forming in the tank and stopping the fuel flow. Check vent and fuel hoses for damage, clogs and kinks.
What is the direction of flow for a fuel filter?
However, most filters contain an arrow that points in the direction of the fuel flow. For proper installation, this arrow should point towards the carburetor. If there is no arrow on the new filter, Briggs & Stratton recommends placing the larger end towards the engine.
What is the flow of fuel in a gravity feed system?
FUEL SYSTEM A gravity feed system is shown in figure 4-7. The fuel tanks are mounted above the carburetor, with gravity causing the fuel to flow from the tanks to the carburetor. A selector valve is provided to stop the fuel flow or to select a particular tank in the system from which to draw fuel.
What is the difference between gravity feed and pressure feed fuel system?
The pump feed system is opposite to a gravity feed system in that the pump is able to provide sufficient pressure to not only move fuel to an engine that is higher than the tank, but to do so with the pressure required for a fuel-injection system.
Can you Gravity Feed diesel fuel?
Diesel fuel can “gravity feed” from the bottom of your RDS auxiliary tank.
What makes a fuel tank DOT approved?
Fuel tanks must be clearly and permanently marked with the manufacture’s name, manufacture date, gallon size, and must state “Meets all FMCSA requirements for non-side mounted fuel tank”, and “not to exceed 95% of capacity.”
What happens if you put a fuel filter on backwards?
A fuel filter put in backwards may restrict or stop the flow of fuel to the engine. If, after changing a fuel filter, the engine suddenly displays a loss of performance, the filter should be inspected for proper installation.
Should a lawn mower fuel filter be full?
Yes, a lawnmower fuel filter should be full. Lack of enough fuel in the filter will hamper the performance and is bad for its health. Lawnmower filters that do not fill up with fuel often signal a problem.
Should the fuel filter be full of fuel?

What are the 4 options that your fuel selector valve provides in a gravity feed fuel system?
If installed, the selector valve provides four options: fuel shutoff to the engine; fuel feed from the right wing tank only; fuel feed from the left fuel tank only; fuel feed to the engine from both tanks simultaneously.
