CAT Fuel Filter & Water Separator Kit for FASS Lift Pumps — 1"-14 Thread Fit, 10µ Suction / 2µ Pressure

CAT 175-2949 water separator and CAT 1R-0750 fuel filter kit replaces the suction and pressure side filters on compatible FASS lift pump systems for improved diesel fuel cleanliness.

This genuine CAT pair is packaged as a matched maintenance set for diesel lift pumps that use 1"-14 threaded filter mounts. The kit combines a 10-micron suction-side fuel/water separator (175-2949) and a 2-micron pressure-side fuel filter (1R-0750), sized and threaded to fit FASS Titanium and Titanium Signature Series bases that are black or gray. It’s a direct-replacement option built to match or exceed original equipment filtration performance so you can service a fuel system quickly and with compatible components.

What does each filter in this kit do?

The suction-side 175-2949 primarily captures water and larger contaminants before fuel reaches the pump, reducing corrosion and wear. The pressure-side 1R-0750 is a fine fuel filter that removes microscopic particles to protect injectors and maintain injection consistency.

• 175-2949: 7.50" tall × 3.7" OD, 10 micron, includes drain valve for water removal.
• 1R-0750: 7.5" tall × 3.28" OD, 2 micron for high-efficiency particle capture.
• Thread: 1"-14 spin-on mount for direct fit on compatible pumps.
• Designed to work together for staged filtration: bulk removal then fine filtration.

Will this kit fit my FASS lift pump?

This kit fits FASS Titanium and Titanium Signature Series pumps that use standard 1"-14 threaded filter mounts and have black or gray bases. It is not compatible with pumps that have red or blue bases or with systems using different thread sizes or layouts.

• Compatible: 1"-14 threaded mounts, black or gray FASS pump bases.
• Not compatible: red or blue base FASS pumps, non-1"-14 mounts.
• Check pump base color and thread before ordering to ensure fitment.

How do these filters install and maintain the system?

Both elements are spin-on style with sealing gaskets for a simple, leak-resistant installation—no special tools required beyond a filter wrench. The suction-side unit includes a drain valve to purge collected water; routine draining and replacement at manufacturer intervals keeps the system operating well.

• Installation: hand-start then tighten with a filter wrench until snug.
• Maintenance: drain water from the separator regularly; replace filters per service interval.
• Seals: factory gaskets provide secure, low-leak connections when properly tightened.

What are the measurable specifications and benefits?

The kit combines a coarser 10-micron separator with a 2-micron pressure filter to deliver staged protection—bulk water and debris removal before fine particle filtration. That staged approach helps reduce injector wear and preserve pump performance without altering system plumbing.

• Dimensions: both filters approx. 7.5" tall for compact fit in common lift pump setups.
• Filtration rating: 10 micron (suction) + 2 micron (pressure) for layered protection.
• Thread standard: 1"-14 spin-on for direct OEM-style replacement.

Who is this for: This CAT filter kit is intended for diesel vehicle owners, fleet managers, and technicians who use FASS Titanium or Titanium Signature lift pumps with black or gray bases and need OEM-quality replacement filters. Choose this kit if you want matched suction and pressure filtration rated for heavy-duty use, easy spin-on installation, and a compact sizing that fits standard lift pump filter mounts.
