CAT Fuel Filter & Water Separator Kit for FASS Titanium Pumps — 1"-14 Thread (175-2949 + 1R-0750), 2µm/10µm Protection

CAT 175-2949 and 1R-0750 together form a complete replacement filter and water-separator kit engineered to fit FASS Titanium-series lift pumps that use 1"-14 threaded filter mounts.

This kit pairs a suction-side fuel/water separator (CAT 175-2949) with a pressure-side fuel filter (CAT 1R-0750) so you can restore filtration performance on compatible diesel lift-pump systems. Both cartridges match the dimensions and thread pattern used on FASS Titanium and Titanium Signature pumps (black or gray base models), letting you swap filters quickly without modifications. The pair targets particulates and bulk water, helping maintain cleaner fuel delivery to injectors under heavy-duty operating conditions.

Will these filters fit my FASS lift pump?

They fit FASS Titanium and Titanium Signature series pumps that use 1"-14 threaded filter mounts and have a black or gray base. They will not fit pumps with red or blue bases. Always confirm your pump base color and thread spec before purchasing.

• Fits 1"-14 threaded spin-on filter mounts
• Compatible with black or gray FASS pump bases
• Not compatible with red or blue base pumps
• Direct replacements for PF-3001/FS-1001 and XWS-3002/FF-3003 equivalents

How do the two filters differ and why use both?

The suction-side CAT 175-2949 is a fuel/water separator designed to remove bulk water and larger contaminants before the lift pump, while the pressure-side CAT 1R-0750 is a fine fuel filter that captures smaller particles under pressure. Using both reduces wear on pumps and injectors and improves fuel-system reliability.

• 175-2949: 10-micron rating, large drain valve for water removal
• 1R-0750: 2-micron pressure-side filtration for fine particle capture
• Sequential protection: separator first, fine filter second
• Both meet OEM dimensions for straightforward replacement

What are the key dimensions and service features?

Both cartridges are approximately 7.5 inches tall, but their outer diameters and micron ratings differ to match their roles. The separator includes a drain valve for manual water extraction; the pressure filter focuses on fine particulate removal to protect injectors and high-pressure components.

• Both filters: ~7.5" height for compatibility
• 175-2949 OD ~3.7" with drain valve for water removal
• 1R-0750 OD ~3.28" with 2-micron media for fine filtration
• Threaded spin-on design for leak-free installation

How simple is installation and maintenance?

Installation follows a standard spin-on procedure: remove the old cartridges, lubricate the gasket, thread the new filters to hand-tight plus specified torque if provided, and prime your system per pump instructions. Regular inspection and scheduled replacement ensure consistent fuel cleanliness and performance.

• Spin-on thread design—no special tools required for removal/installation
• Lubricate gaskets and hand-tighten; use torque spec if available
• Drain separator periodically using the built-in valve
• Replace both elements at recommended service intervals for best results

Who is this for: Diesel owners and fleet technicians running FASS Titanium or Titanium Signature lift pumps (black or gray base) who need a reliable replacement filter kit that combines bulk water separation with fine pressure-side filtration. Ideal for heavy-duty trucks, commercial rigs, or any diesel application where maintaining clean fuel and protecting high-pressure components is a priority. If your pump uses a red or blue base or a different thread size, check your model and select a compatible cartridge set.
