The petcock allows me to check for water or dirt in the fuel system without removing the filter. Dirt and water pools at the bottom of the canister , I can bleed it off into a clear bottle for evaluation. I use these on my boat because after 5 months of winter layup moisture enters the gas tank and contaminates the fuel. These filters are worth the extra expense they can save you from buying a replacement filter just by draining off the contaminates should the engine begin to stall in the spring. I have been using 3123 NAPA GOLD filters for 22 years now. You can get several years out of one of these filters.

Counter clockwise ?** A: Yes, Counterclockwise. I like this filter because I can open the drain into a clear plastic bottle and inspect the contents for water. **Q: is this filter similar to the napa 4006 filter?** A: I suggest you contact NAPA for this question. Because I am not familiar with the napa 4006 filter. I have been using the 3123 for over 15 years. It is an outstanding filter. **Q: How does the drain work? Open it and water runs out? This would be for a conversion project. Thanks.** A: Yes, it is a fuel filter/water separator. It works well. I believe it is 12 micron. I use it as a prefuel filter before getting to the oem filters. I've been using these filters for a while on customers vehicles. Since doing so I never get any water out of the oem separator. Sometimes the drain cock on the filter gets plugged with debris and will not drain. I just shoot a little air up the drain, but stand back because it will shoot out once you move the air out of the way. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This is an excellent filter ! *by N***N on October 9, 2017* I have tried several different fuel / water filters , this filter has a petcock on the bottom.
