Fuel Filters Canisters Maintenance & Technology


Proper fuel filter maintenance is critical to keeping today’s high tech engines running properly, with just a little extra time and minimal expense you can save hundreds or thousands of dollars in costly fuel system repairs.

Replace filters every 50 hours of operation or at a minimum of once per year, preferably at winterization.

Upgrade your filter if possible. 10-micron filters are available for most engine configurations. Upgrade from a 21-micron to a 10-micron and keep more engine clogging dirt and debris from entering the fuel system. Plus, 10-micron filters are your number one defense against problems caused by ethanol based fuels.

Inspect fuel lines and filter head for leaks and damage. If in doubt, replace the part.
Always add a light coating of motor oil to the seal of the fuel filter to allow for easy removal.
Do not over-tighten filters, and always inspect for leaks after installation.
Dispose or your old filter properly. Most service, parts and quick lube facilities will allow you to drop off old filters for proper disposal.
