DICMIC Fuel Tank Filter Assembly 30 Micron Water-Separating Inline Filter with Clear Bowl, 3/4" NPT, 25 GPM

DICMIC's fuel tank filter assembly is a water-separating 30-micron inline filter with a clear bowl, 3/4" NPT top cap, and wrench for fast replacement that supports gasoline, diesel and up to B20 blends.

This compact filtration unit is built to reduce particulates and remove free water from stored fuel before it reaches engines, pumps, or dispensing nozzles. The assembly includes a protective sheet-wrapped 30µm element, a transparent (hyaline) collection bowl with a drain valve, and a top cap fitted for 3/4" NPT inlet and outlet connections. Designed for up to 25 gallons per minute flow and 150 psi working pressure, it also functions by gravity around 5 GPM for low-pressure setups.

How does this filter protect my engine and fuel system?

The 30-micron element captures rust, dirt, sand and other solids that accelerate wear in fuel pumps and injectors, while the clear bowl lets you visually monitor contamination and water accumulation. Removing these contaminants helps maintain reliable flow and reduces maintenance frequency.

• 30µm filtration media with protective sheet to prevent element damage
• Transparent hyaline bowl for quick visual checks
• Bottom drain valve to purge separated water without disassembly
• Protects downstream fuel delivery components from abrasive particles

What fuels and installation formats does the DICMIC assembly work with?

This unit is compatible with unleaded gasoline, diesel, fuel oil and blends up to 20% biodiesel (B20). The top cap features clearly marked IN and OUT ports with 3/4" NPT threads for straightforward plumbing into tank-to-pump or transfer lines.

• Suitable for gasoline, diesel, fuel oil and B20 blends
• 3/4" NPT inlet/outlet threaded top cap for common fittings
• Can be used in pressurized systems up to 150 psi or gravity-fed lines (~5 GPM)
• Includes wrench and tape for correct seal and easy service

How do I install and service the filter safely and quickly?

Installation is hand-tighten simple: fasten the top cap to the tank valve marked IN, attach hose/nozzle to OUT, then seat the element and bowl using a light oil coating on the gaskets. Use the included wrench only as needed; overtightening the bowl can make later removal difficult.

• Apply light oil to both sides of the gasket during assembly
• Hand-tighten bowl and cap; use wrench gently to avoid over-torquing
• After assembly, check all connections for leaks under pressure
• Drain separated water through the bottom valve before replacing the element

What performance can I expect under normal use?

The filter handles up to 25 gallons per minute at rated pressure, with a gravity flow around 5 GPM for passive setups. It is rated for working pressures up to 150 psi and is supplied with a reinforced element to withstand flow variations without collapse.

• Maximum flow: 25 GPM at system pressure
• Gravity flow: about 5 GPM for low-pressure transfer
• Maximum working pressure: 150 psi
• Filter element reinforced with protective sheet to resist deformation

Who is this for: The DICMIC Fuel Tank Filter Assembly is targeted at fleet operators, marine and recreational vehicle owners, farm and construction equipment users, and anyone who stores or transfers fuels and needs reliable particulate and water removal. It suits technicians and DIYers who want a visible, serviceable filter solution that installs with common 3/4" NPT fittings and provides high flow capacity for pumps and dispensing systems.
