LTZLL 1200KTF7018 Fuel Filter Assembly — 10‑Micron Spin‑On, 18 GPM, 3/4" NPT

The LTZLL 1200KTF7018 is a complete 10-micron spin-on fuel filter assembly for transfer pump systems, delivering up to 18 GPM flow with 3/4" NPT ports and a 50 PSI rating.

This assembly is designed as a direct replacement for common Fill‑Rit and Grainger transfer pump filters, combining a spin‑on filter element with a cast‑aluminum filter head and the fittings needed for a straightforward installation. It removes particulate down to 10 microns, sheds moisture from fuel, and is rated for diesel, gasoline and ethanol blends up to 15%—making it suitable for many on‑site fuel transfer applications in agriculture, construction and fleet service.

How does this assembly fit my existing transfer pump?

The kit includes a 1"‑12 UNF threaded spin‑on filter and a cast‑aluminum head with 3/4" NPT inlet/outlet ports, matching common Fill‑Rit and Grainger filter models. Installation is straightforward: thread the filter onto the head, connect the 3/4" piping, and seal with the supplied Teflon tape.

• Ports: 3/4" NPT inlet and outlet for direct pump plumbing
• Thread: 1"‑12 UNF spin‑on filter connection
• Included parts: cast‑aluminum filter head, spin‑on filter, elbow, 7" nipple, Teflon tape

What level of filtration and performance can I expect?

This unit provides a 10‑micron particulate rating to capture rust, sand, fibers and similar contaminants, plus a design that separates and reduces free moisture in fuel. It’s sized for up to 18 GPM flow at a maximum working pressure of 50 PSI, suitable for most diesel and gasoline transfer pump tasks.

• Micron rating: 10 microns for particulate control
• Flow capacity: up to 18 GPM (68.1 LPM)
• Max pressure: 50 PSI (3.4 BAR)

Which fuels and environments is the filter assembly compatible with?

The assembly is intended for diesel, gasoline and ethanol blends up to 15% (E15). It is not intended for water‑based liquids, aviation or competition fuels. The construction and filtration media are chosen to resist common contaminants found in field fuel tanks and mobile fuel transfer systems.

• Fuel types: diesel, gasoline, ethanol blends ≤15%
• Not for: water‑based products, aviation or race fuels
• Best used in: farm, construction, service fleet, and remote fueling stations

What maintenance or replacement schedule should I plan for?

Replace the spin‑on filter element when flow decreases or when the differential pressure indicator on your system (if equipped) signals service. Regular inspection after heavy debris exposure or seasonal storage will help avoid pump wear; always keep a spare filter and the included fittings on hand for quick swaps.

• Monitor flow and pressure drop for replacement cues
• Carry a spare F1810PM0 spin‑on element for rapid changeover
• Inspect fittings and seals during each service to prevent leaks

Who is this for: The LTZLL 1200KTF7018 assembly suits technicians and operators who maintain mobile fuel transfer systems, on‑site fueling for machinery, or fleet fuel points that need reliable particulate and moisture control. It’s ideal when you require direct compatibility with Fill‑Rit and Grainger transfer pump models, want a quick spin‑on service solution, and need a robust assembly that supports up to 18 GPM at 50 PSI.
