Does what it’s supposed to at a fair price. ### ⭐⭐⭐⭐⭐ Good Quality *by T***J on December 16, 2024* Easy to install. Fit was perfect. I like Sierra filter quality for the money. I will definitely buy this filter again. ### ⭐⭐⭐⭐⭐ Great filters *by C***I on January 4, 2016* I have always used these on all of my boats. They seem to be made of great quality, I have never had any problems with the paint peeling off of the out side of the filter if the fuel get on it during the installation. before selling my last boat, they had been installed for roughly a year, and were still holding up very well. I was surprised that they still looked so good after being in a boat with a wet hull (inboard motors that the shaft seals drip to cool them underway), that sat in the marina year round. When I sold my last boat, these filters had roughly 80 hours of run time on them, and were used in a system with twin 5.7L MPI captains choice crusader motors. I have recently installed these on a boat that I have just purchased. This current boat is a Glacier Bay 2680 with twin Yamaha outboard motors. I have about 15 hours on them since they were installed, and the motors run great, and don't seem to have any issues pulling fuel through these. --- ## 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.be/products/2594095-teleflex-18-7944-fuel-water-separator-filter-original-version-medium](https://www.desertcart.be/products/2594095-teleflex-18-7944-fuel-water-separator-filter-original-version-medium) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-19*
