DICMIC Fuel Tank Filter Assembly 30‑Micron 25 GPM, Hyaline Sight Bowl & Wrench, 3/4" NPT

The DICMIC Fuel Tank Filter Assembly is a heavy‑duty in‑tank filtration system with a 30‑micron element, hyaline bowl and wrench for easy installation, rated to 25 GPM and 150 PSI.

This compact filter assembly is built to keep common fuels — gasoline, diesel and up to B20 biodiesel — cleaner before they reach pumps and engines. It pairs a 30‑micron filter element protected by a backing sheet with a clear (hyaline) sight bowl and a bottom drain valve, enabling visual inspection and fast water removal. The top cap includes clearly marked IN and OUT 3/4" NPT ports and the kit ships with a matching installation wrench and sealing tape to simplify setup.

How does this filter help maintain a fuel system?

The 30‑micron element traps particulate contaminants like rust, sand and dirt while the protective sheet prevents deformation under pressure. The clear bowl lets you see contamination and fuel flow changes so you can replace the element before issues escalate. A bottom drain valve makes separating and removing water straightforward.

• 30‑micron filter element with protective sheet for durability
• Hyaline bowl for visual monitoring of fuel condition and debris
• Drain valve to remove separated water without disassembling
• Top cap with IN/OUT 3/4" NPT fittings for standard plumbing

What flow rates and pressures can it handle?

The assembly supports a maximum flow up to 25 gallons per minute under pressure and works with systems up to 150 PSI, covering many transfer and dispensing applications. For low‑head gravity feed scenarios, expect approximately 5 GPM; this is useful for slower transfer from storage tanks. These ratings make it suitable for medium‑duty fueling and refueling tasks where consistent flow and filtration are required.

• Maximum flow: 25 GPM (pressurized)
• Working pressure: up to 150 PSI
• Gravity flow: about 5 GPM for low‑pressure setups
• 3/4" NPT inlet/outlet for common hose and nozzle fittings

How do I install and service the filter assembly?

Installation is straightforward: attach the top cap to the tank valve marked "IN," connect hose/nozzle to the port marked "OUT," and hand‑tighten the bowl with a light oil coating on the gaskets to ensure a good seal. The included wrench and sealing tape help seat fittings correctly without over‑torquing; avoid tightening the bowl aggressively to prevent future removal issues. When the sight bowl shows debris build‑up or fuel flow noticeably slows, replace the element and inspect gaskets.

• Hand‑tighten bowl only; use included wrench for the cap
• Coat both gasket faces lightly with oil before assembly
• Check for leaks after installation and during first use
• Replace element when fuel flow declines or bowl shows contamination

Which fuels and components is this compatible with?

This filter was designed to work with standard fuels: unleaded gasoline, diesel, fuel oil and biodiesel blends up to 20% (B20). It is intended for in‑tank or near‑tank filtration on transfer and dispensing lines and is compatible with common hose/nozzle setups that use 3/4" NPT fittings. The materials and element construction are chosen for fuel service, but follow fuel‑specific guidelines for safety and compatibility.

• Compatible with gasoline, diesel, fuel oil and B20 biodiesel
• 3/4" NPT connection fits a wide range of fueling hoses and valves
• Transparent bowl for quick visual checks across fuel types
• Protective element sheet prevents damage under pressure

Who this is for: The DICMIC Fuel Tank Filter Assembly is suitable for fleet managers, service shops, agricultural operators and DIYers who need a reliable, serviceable in‑tank filter for transfer and dispensing systems. It’s especially useful where particulate contamination or water in stored fuel can cause pump or engine problems, and for anyone who wants visual monitoring plus straightforward maintenance without specialized tools.
