Melling Oil Pump Screen 55S1 - Galvanized Steel 0.50" I.D., 0.75" Length for OEM Fit

The Melling Oil Pump Screen 55S1 is a galvanized-steel pickup screen designed to protect your engine by filtering debris before oil reaches the pump.

This compact replacement screen fits standard oil pickup setups where a durable, corrosion-resistant inlet filter is required. Manufactured in the U.S.A., the 55S1 combines a 0.50 inch inside diameter with a 0.75 inch overall length to match original-equipment dimensions while providing reliable particle screening to prolong pump life.

What does the 55S1 screen do inside the oil system?

The 55S1 sits at the oil pump inlet to stop larger contaminants and metallic particles from entering the pump housing. That reduces the risk of scoring and wear on internal pump parts and helps maintain steady oil flow under normal operating conditions.

• Acts as the first barrier against sludge, metal flakes, and debris
• Prevents blockage and abrasive wear on pump gears and vanes
• Maintains oil flow consistency for effective lubrication
• Galvanized finish adds corrosion resistance in wet environments

Will the dimensions of the 55S1 fit my application?

The screen has a 0.50 inch internal diameter and measures 0.75 inch long, so compatibility depends on your pump inlet size and pickup tube geometry. Check your original screen or repair manual measurements to confirm fit before installation.

• 0.50" I.D. for standard small-diameter pickups
• 0.75" total length for shallow inlet housings
• Galvanized-steel build that matches many OEM replacement specs
• Made in U.S.A. for traceable manufacturing standards

How do I install the Melling 55S1 oil pump screen?

Installation is typically straightforward: remove the oil pump or pickup tube assembly, slide the screen over the inlet, and secure according to your pump’s fasteners or retaining method. Always follow the vehicle or pump manufacturer’s service instructions and use proper torque and sealants if called for.

• Requires basic hand tools and a clean workspace
• Inspect pickup tube and mating surfaces for wear before fitting
• Replace gaskets or seals removed during disassembly
• Confirm orientation so the screen faces incoming oil flow

How durable is the Melling galvanized steel construction?

Galvanized steel provides good resistance to rust and abrasion for typical engine oil environments. While suitable for standard passenger vehicles and many light-duty engines, screens should be inspected during routine service intervals and replaced if deformed or clogged.

• Galvanized coating helps prevent oxidation over time
• Sturdy enough to withstand oil pressure and handling during installation
• Replace if dented, punctured, or heavily fouled
• Manufactured in the U.S.A. with consistent quality control
