## Questions & Answers

**Q: What way do i turn to drain? 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.
