FAQ:

Q: What is a bad fuel filter?

A: A common warning sign that a fuel filter is going bad is that the engine will begin to miss at highway speeds because the fuel filter is clogged and is not allowing adequate fuel flow to the engine, according to Aa1car.com. As the engine misses, the engine will jerk.

Q: Can a bad fuel filter affect gas mileage?

A: Bad oxygen sensors and clogged air filters are the most common mechanical causes of bad gas mileage. A clogged air filter reduces the flow of fresh air to the engine, which causes the engine to work harder. The oxygen sensor is responsible for regulating the air and fuel.

Q: Does Fleetguard make Mopar filters?

A: Ok, so found out Fleetguard makes Mopar. Fleetguard is a Cummins subsidiary, so you can be assured of the quality of filtration. You’ll be fine with either one you choose. Mopar and Parker / Racor are all OEM filters on 2013 & up pickups. Click to expand…

Q: Where is the fuel filter on a diesel engine?

A: The air filter setup on most diesel engines is the same as on gasoline-powered vehicles, with the filter located inside the cold air collector box located under the hood.
