Buying Guide
Key purchase considerations help narrow the field to a filter that fits your vehicle and maintenance schedule.
- Vehicle compatibility: Check hose sizes (⅜”, ½”, ⅝”) and return-line fittings. Some filters list universal compatibility, others specify exact fit. Choose based on whether you own a modern import, domestic, or heavy-duty truck.
- Filtration capacity: Higher-capacity meshes can remove more particulates and maintain better fluid quality. Look for stated mesh size, magnet strength, and whether the unit is serviceable.
- Construction and durability: Stainless steel meshes and aircraft-grade bodies resist corrosion and wear. Polycarbonate casings offer visibility but may have temperature considerations.
- Installation and maintenance: Serviceable baskets and easy access for cleaning reduce downtime. Direct replacements save time during pump servicing.
- Application scope: For mixed fleets, a universal or adaptable filter can minimize inventory. For single-application trucks, a model aligned with OEM specs can ensure reliability.
