Good price. *by S***R on February 22, 2026* works perfect. i installed in the frame of my kubota bx24 after having the filters freeze in cold weather. the stock filters had no way to drain water from the fuel. I can now access without having to crawl under the tractor. ### ⭐⭐⭐⭐⭐ High Quality *by J***O on March 11, 2026* I’ve got this same filter on 4 of my boats. It’s very durable and zero issues. It’s as good as a Racor filter that cost 150.00 more. I highly recommend ### ⭐⭐⭐⭐⭐ It works GREAT, and it is easy to drain the water out. *by K***R on May 20, 2026* It was easy to mount, easy to hook up and it works wonderfully. It has an easy to use drain valve that keeps your hands clean. In addition, I bought barbed adapters to fit from a 3/8" fuel line to a 1/4" fuel line for the Zero Turn mower I put this on. I HIGHLY suggest buying fuel hose that has the nylon reinforcement (I went to NAPA). The Chinese sourced fuel hose is single walled, thin and did not want to hold a good seal. I almost started my mower on fire while using it because of the thin wall Chinese fuel line was leaking... Again, I HIGHLY SUGGEST buying Quality strong reinforced fuel line. ## Frequently Bought Together - CARMOCAR Marine Fuel Water Separator/Diesel Fuel Filter/Water Separator for R12T MARINE SPIN-ON HOUSING 120AT NPT ZG1/4-19 Includes 2 fittings,2 plugs - 3/8 Inch (10mm) ID Fuel Line Hose 10FT NBR Rubber Push Lock Hose High Pressure 300PSI for Automotive Fuel Systems Engines - CarBole Universal 12 Volt Electric Fuel Pump 5-9 PSI, 35GPH, Super 12D for Diesel Engines --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/95222412-marine-fuel-water-separator-diesel-fuel-filter-water-separator-r12t](https://www.desertcart.hr/products/95222412-marine-fuel-water-separator-diesel-fuel-filter-water-separator-r12t) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-23*
