Diesel Pickup Fuel Filter Changes

We use original equipment (OEM) fuel filters for fuel filter changes. We recommend changing the fuel filter(s) every 7,500 – 10,000 miles.

Many major brand aftermarket fuel filters do not have the same micron rating as the OE filter. The larger the micron rating, the larger the contaminate size is that enters the fuel system. If the OE spec is 5 microns, we don’t use a 14 micron filter for Ford Powerstrokes. If the OEM specification is 2 microns, we don’t use a 5 micron filter for Duramax. Excess fuel system wear results from particles too large passing through the fuel filter.

The following prices are for OEM filter changes. Prices may increase if you have additional filters or non-original filters.
