Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Selector Valve: Description: Notes
Two fuel selector valves are used. Gasoline engine models use a mechanically-activated dual function reservoir, while diesel equipped vehicles use a 6-port fuel selector valve.
The dual function reservoir combines reservoir/filter function with tank selector valve function. The dual function reservoir system uses 3 fuel pumps: 2 low pressure pumps in tank and one external high pressure pump. The 6-port fuel selector valve does not contain a filter or reservoir and a single mechanical fuel pump.
