Product Overview
The R25T clear nylon water collection bowl is a direct replacement drain bowl for your S3213 fuel water separator or 245R series filter assembly. Over time, original bowls can crack from impact, cloud from UV exposure, or develop seal leaks at the O-ring — any of which compromises your ability to inspect fuel condition. Instead of replacing the entire filter assembly, swap in a fresh R25T bowl for a fraction of the cost. Quick screw-on installation — no special tools, no mechanic required.
Key Features
Clear Nylon Construction: Crystal-clear visibility for instant fuel inspection. Spot water accumulation before it becomes an engine problem.
Direct Replacement: Fits S3213 clear-bowl filter assemblies and 245R series fuel filter housings. Same thread pattern, same seal dimensions.
UV-Stabilized & Ethanol-Resistant: Engineered not to yellow, cloud, or degrade with E10 fuel or prolonged sun exposure.
Includes O-Ring Seal: Fresh factory seal included — no need to reuse an old, potentially flattened O-ring that could cause vacuum leaks.
Tool-Free Install: Hand-tighten, then a light quarter-turn with a strap wrench. Done in under 2 minutes.

Why Choose This Bowl
A cloudy or cracked bowl isn't just annoying — it's a safety risk. If you can't see the fuel, you can't tell when water has built up to dangerous levels. This R25T replacement restores full visibility and water-detection capability. Our bowls ship from US inventory and include a fresh O-ring so you get a leak-free seal on the first install. At a fraction of the cost of a new filter assembly, it's the smart fix.
Frequently Asked Questions
Q: How do I know if my bowl needs replacing?
A: Replace if the bowl is cloudy or yellowed (can't see fuel clearly), cracked or chipped, or leaking fuel from the seal area. If water droplets are visible inside even after draining, the O-ring may have failed — this kit includes a fresh one.
Q: Will this fit my standard sealed S3213 filter?
A: No — the sealed one-piece S3213 has no bowl port at all. This bowl only fits S3213 assemblies that originally came with a clear drain bowl, or the 245R series filter housings.
Q: Is installation difficult?
A: Not at all. Unscrew the old bowl (have a rag ready — expect some fuel), remove the old O-ring, fit the new O-ring onto the new bowl, and screw it on. Hand-tight plus a quarter-turn with a strap wrench is all you need.
Q: Can I upgrade my sealed S3213 by adding this bowl?
A: No — the sealed S3213 body is a one-piece design with no threaded port for a bowl. If you want a clear-bowl filter, you'll need one of our S3213 assemblies that includes the bowl port (see links below).
Q: Will this bowl yellow over time like my old one did?
A: The R25T nylon is UV-stabilized for significantly better resistance to yellowing than earlier-generation bowls. With reasonable care, it should remain clear for multiple seasons.
Q: Does this include the drain valve?
A: The bowl includes the bowl body and O-ring seal. The drain valve is part of the filter assembly body, not the bowl itself. If your drain valve is damaged, you may need a full filter assembly replacement.
