Built with a reusable, washable design, this filter delivers long-term value without compromising flow or requiring frequent replacements.

The removable, O-ringed end caps make cleaning quick and straightforward—simply rinse the stainless steel element and reinstall. With 3/8-inch NPT female fittings, it integrates seamlessly into most fuel lines.
