Where are diesel fuel filters located?
Most diesels have two fuel filters: a “primary” filter located between the fuel tank and the engine, which cleans the fuel before it gets to the fuel transfer pump; and a “secondary” filter up near the engine, which gives the fuel a final cleaning before it gets to the fuel injectors.

How do I know when to change my diesel fuel filter?
Diesel fuel is by nature, quite dirty, so it makes sense that the fuel filter is one of the most important filters on any diesel application. They usually require a change every 10,000 to 15,000 miles whereas a modern gasoline fuel filter could go 100K+ miles before a change is needed – if at all.
How much does it cost to change a diesel fuel filter?
Most fuel filters can be replaced within an hour so plan on around $60 to $120 in labor. Some in-tank filters or those that are part of the fuel pump assembly may require additional labor time. On average, the total cost of fuel filter replacement will be around $70 to $160 which includes parts and labor.
Can you clean out a diesel fuel filter?
If your filter is nylon or paper, you should just replace it with a new one. If it’s made of metal and isn’t too grimy, you can clean and reuse it. Remove the filter from the fuel lines, then spray it with a solvent cleaner.
What happens if you dont change diesel fuel filter?
If you don’t change your fuel filter when recommended to, there is a very high chance the filter will become clogged with debris. Which means it can no longer filter all the fuel.
How do you check a diesel fuel filter?
Loosen the hose clamp on the fuel line that goes into the fuel filter from the gas tank by using a flat-head screwdriver to turn the clamp screw counter-clockwise several times . Hold the fuel filter so it is tilted up slightly, and pull the fuel line off. This way the gas in the filter will not spill out.
How can you tell if your fuel filter is clogged?
Use a large straw or a small hose and apply it to one end of the fuel filter. Blow into the straw or hose. If your breath goes through with little resistance, your fuel filter is still in good condition. If you have a hard time blowing air through the fuel filter, then it is clogged and must be replaced.
