DICMIC Fuel Tank Filter Assembly 30‑Micron 3/4" NPT Clear Bowl — 25 GPM, 150 PSI, Wrench Included

DICMIC's Fuel Tank Filter Assembly is a heavy-duty inline fuel filter system with a 30‑micron element, clear hyaline bowl and wrench included for quick installation and reliable particle and water separation.

This filter assembly is built to protect fuel systems used with gasoline, diesel and up to B20 biodiesel. The unit combines a 30‑micron pleated element with a protective sheet, a transparent bowl with drain valve for visual inspection, and 3/4" NPT inlet/outlet ports. It supports a maximum flow of 25 gallons per minute and handles working pressures up to 150 psi while allowing gravity-fed operation near 5 gpm.

How do I install the DICMIC fuel tank filter assembly?

Installation is straightforward and designed for hand tightening to avoid over-stressing the bowl. Fit the cap to the tank valve marked "IN," connect the hose and nozzle to the cap outlet marked "OUT," seat the element and bowl using a light oil layer on the gasket, and use the supplied wrench only as needed.

• Attach top cap to tank valve at the "IN" opening.
• Connect hose/nozzle to the "OUT" fitting (3/4" NPT).
• Lubricate gaskets with oil, hand-tighten bowl and cap; check for leaks.
• Use drain valve on hyaline bowl to remove collected water.

What contaminants and fuels is this filter compatible with?

The DICMIC assembly is suitable for common liquid fuels and addresses particles and free water that harm pumps and injectors. Its 30‑micron element captures rust, sand and sediment while the protective outer sheet maintains element shape under pressure.

• Compatible with unleaded gasoline, diesel, fuel oil and up to 20% biodiesel (B20).
• Captures particles down to 30 microns; protective sheet prevents deformation.
• Hyaline bowl lets you detect slow flow or visible contamination quickly.

What are the flow and pressure limits, and how will they affect my setup?

This filter supports high-flow refueling and also works in low-pressure gravity-fed systems. Expect up to 25 gpm under pressure, suitable for many transfer and dispensing tasks, while gravity-only setups will see about 5 gpm.

• Maximum flow rate: 25 gallons per minute (pressure-assisted).
• Working pressure rating: up to 150 psi for pressurized systems.
• Gravity flow: approximately 5 gpm for non-pressurized applications.

How do I maintain or replace the filter element?

Routine inspection of the hyaline bowl makes maintenance predictable: replace the element when flow decreases or contamination becomes visible. Turn off fuel supply, relieve pressure if present, hand-remove the bowl, swap the element, lubricate the gasket, reassemble and check for leaks.

• Inspect bowl visually; replace element when flow slows or debris appears.
• Hand-tighten components; avoid over-torquing to enable future removal.
• Use the included drain valve to purge water before element change.

Who is this for: The DICMIC Fuel Tank Filter Assembly suits fleet operators, farm and construction equipment owners, service stations and anyone needing to protect fuel pumps and engines from particulate and water contamination. It’s ideal where compatibility with gasoline, diesel and B20 matters, where quick visual inspection is helpful, and where a reliable 30‑micron filtration with a clear bowl and simple maintenance is required.
