  • Buna-N gasket ensures a durable, leak-resistant seal

Fuel Filtration Kit

The Dayton 40M302 Filter Kit is a canister-style fuel filter designed to remove particulate and water contamination. It handles a maximum flow rate of 25 gpm at an operating pressure up to 50 psi. The unit carries a 10 micron filter rating for fine contamination control. Connections use 1 1/2 in UNF threads on both intake and discharge ports.

Diesel Equipment Maintenance

This kit suits operators maintaining diesel fuel systems who need combined water and particulate removal at moderate flow rates. It is not intended for applications exceeding 50 psi or 25 gpm throughput. Buyers requiring higher pressure ratings or larger port sizes should look at alternative filtration hardware. The Buna-N gasket material determines chemical compatibility limits.

10 Micron Filter Rating

The single specification that decides fitment is the 10 micron maximum filter rating. This rating defines the smallest particle size the media captures under test conditions. Verify that your engine or system manufacturer specifies this micron level for adequate protection. A finer or coarser rating will not meet the same cleanliness target.

Questions about this item

How do I install the 1 1/2 in UNF connections without cross-threading?

Hand-tighten the UNF threads on both the 1 1/2 in intake and discharge ports until the Buna-N gasket seats, then finish with a wrench; the step most people skip is lubricating the gasket first.

When will the 10 micron filter element need replacement?

Replace the canister element when flow drops below 25 gpm or pressure rise indicates the media is saturated with particulate and water.

What pressure limit appears first during continuous operation?

The 50 psi maximum operating pressure is the first limit reached under sustained use.
