Review on Wix 33003 Line Fuel Filter by Predrag Holman

This plastic body fuel filter works well with my power hungry 150hp outboard. I was expecting it to fill up completely with fuel during use, but it actually doesn't. It stays about half full of air, but the engine-driven pump has never run out of fuel. I believe that the fuel enters the outside of the medium and goes straight to the outlet nipple/port, keeping air out of the fuel flow (otherwise my engine would oscillate). The transparent case allows me to see if water gets into the fuel stream as water can collect at the bottom of the corner assembly I created. Excellent results on a user designed/installed auxiliary (portable) fuel tank for my boat. I wouldn't recommend this in an indoor housing as only an all metal filter should be installed in a closed mechanical area, but for my external tank setup it's perfect.
