LANTU R90T Fuel Filter Water Separator | 1001312 FS19551 | Cum mins & Foton Aumark

Product Overview

The LANTU R90T Fuel Filter is a spin-on diesel fuel filter and water separator designed for compatible commercial vehicles and diesel engine fuel systems.

The supplied product is marked with three part numbers: R90T, 1001312, and 1117211-P301. These markings help customers identify the product, although compatibility must be verified against the original filter specifications.

The R90T reference group is associated with selected Cum mins diesel engines and Foton Aumark commercial vehicles. Related R90P filter references are also included below to help buyers distinguish between different product configurations.

LANTU supplies aftermarket filtration products for commercial vehicle parts wholesalers, diesel engine parts distributors, and international bulk buyers.

Technical Specifications

Note: These dimensions are based on the supplied R90T reference information and refer to the filter element rather than the complete assembly with bowl. Another catalog lists a nominal diameter of 110 mm. Final product dimensions and bowl configuration should be confirmed before ordering.

Fuel Filter Cross Reference

The following part numbers are listed in the available R90T catalog reference information.

Cross Reference Notice: These numbers are provided for identification and reference purposes. They do not guarantee direct interchangeability. Buyers should confirm dimensions, thread size, water separator configuration, and vehicle compatibility before replacement.

R90T and R90P Filter Specifications Comparison

The supplied product catalog also includes a related R90P / 1117211-P301 filter group.

Although some part numbers are associated with the same product family, their physical specifications may differ.

The primary R90T technical specification is listed as 108 mm in outer diameter based on the supplied reference data, while the catalog comparison uses the nominal 110 mm diameter.

Related R90P / 1117211-P301 Cross References

Important: The 1117211-P301 number is printed on the supplied product, but the catalog also associates this number with a longer R90P-related filter. Therefore, printed part numbers alone should not be used to determine interchangeability.

Vehicle and Engine Applications

The following information is based on the available product catalog references.

Application Note: Vehicle compatibility depends on the installed fuel filter assembly. Customers should verify the original filter number and relevant equipment specifications before purchasing.

How to Choose the Correct Replacement Fuel Filter

Selecting the correct replacement requires checking both the part number and physical specifications.

Before placing an order, please confirm:

1. Original Part Number: Check R90T, 1001312, FS19551, 1117211-P301, or other relevant markings.

2. Filter Dimensions: Compare the outer diameter and overall filter height with the existing part.

3. Thread Connection: Confirm the thread size and mounting compatibility.

4. Water Separator Configuration: Verify whether a separate water collection bowl is required and whether its connection is compatible.

5. Vehicle or Engine Application: Provide the vehicle model, engine model, or existing filter assembly information.

Customers may also send photos of their existing filters to LANTU for identification and compatibility review.
