VIKKSAER Remote Fuel Filter Base 4770/24770 — Fits CAT 1R-0749/1R-0750, 1/2" NPT Ports

VIKKSAER 4770/24770 is a heavy‑duty remote fuel filter base that replaces CAT 1R‑0749 and 1R‑0750, letting you mount compatible diesel water‑separating filters off‑engine for easier service.

This precision replacement base is built to accept common diesel fuel/water separator cartridges and to withstand high‑temperature, heavy‑use environments. Made from durable materials with standard thread sizes, it gives a secure mounting point for filters used on trucks, construction equipment, agricultural machinery, and other diesel systems. The unit ships with the mounting screws and carries a one‑year quality warranty.

Which OEM filters and part numbers does this base replace?

The VIKKSAER 4770/24770 base is engineered as a direct replacement for CAT part numbers 1R‑0749 and 1R‑0750. It is also compatible with select NAPA and WIX water separator cartridges commonly used in fleet and industrial applications.

• Direct CAT replacements: 1R‑0749, 1R‑0750.
• NAPA cross references: 3405, 3528, 3352 (various micron ratings).
• WIX cross references: 33405, 33528, 33352 (water separator types).

What are the key dimensions and thread types I need to know?

Before ordering, confirm thread and plumbing compatibility with your system. This base uses standard thread sizes found on many remote diesel filter mounts to simplify swaps without custom plumbing work.

• Base mounting thread: 1"‑14 TPI (threads per inch).
• Inlet and outlet ports: 1/2" NPT (national pipe thread).
• Includes two screws for secure installation; no cartridge included.

How does the construction affect durability and performance?

VIKKSAER designs the base from a high‑strength material formulated to tolerate elevated operating temperatures and repeated service cycles. That construction helps maintain seal integrity and hose alignment in demanding environments.

• Robust alloy construction resists deformation under heat and vibration.
• Precision machined ports ensure leak‑free connections when used with proper fittings and seals.
• Supplied mounting hardware anchors the base for stable remote installations.

Will this fit my fuel/water separator cartridge and where should I check fitment?

This base accepts several common cartridge families, but filter dimensions and micron ratings vary. Always verify the cartridge part number and compare the product images and thread specs before purchasing to ensure a correct match.

• Designed for multiple micron rating cartridges including 2, 6, and 14 micron variants (as used across brands).
• Compare your existing cartridge's mating thread and overall height to ensure clearance and correct sealing.
• Check system plumbing for 1/2" NPT compatibility or adaptors if needed.

Who this is for: This VIKKSAER fuel filter base is intended for fleet mechanics, equipment owners, and service technicians who need a reliable remote mounting solution for diesel fuel/water separators. It's a practical choice if you're replacing a worn or damaged CAT 1R‑0749/1R‑0750 head, retrofitting a remote filter location, or standardizing parts across NAPA/WIX cartridge types. Confirm thread sizes and cartridge cross‑reference before ordering to ensure a quick, trouble‑free install.
