FAQ

What is the WS100?

It replaces the water-separation element on the listed AirDog systems. It works with the systems separate fuel filter; the two elements perform different jobs and are not interchangeable.

What application does this version fit?

AirDog I, AirDog II, AirDog II-4G and AirDog II-5G filter bases. This service separator is not the separate fine fuel filter.

What is included with this listing?

One replacement water separator.

Does this replace every similar-looking component?

No. Match the products function, connections and complete system configuration; appearance alone does not establish compatibility.

How should pressure or electrical setup be selected?

Use the actual engine and system requirements in the linked guide. A GPH rating is flow, not pressure; increasing pressure beyond specification can damage the system.

What should be checked before installation?

Check the installation location, connections, required tools and supplied components against the exact guide. Do not adapt a different vehicle kit solely because the pump looks similar.

Are additional parts supplied automatically?

No. A gauge, sender, additional fittings, separate regulator or complete fuel system is included only when expressly named in Whats Included.

What should be checked before driving?

Follow the priming and startup procedure, inspect every fuel and electrical connection, verify pressure with appropriate equipment, and check for leakage and hose abrasion.

Installation Instructions

1. Isolate the system and contain any drained diesel fuel.
2. Remove the separator using the service procedure for the installed AirDog system.
3. Inspect the mating seal and fit the replacement without introducing dirt.
4. Close the drain, prime as directed and inspect for leakage.
