## Questions & Answers

**Q: Can this be used with 11/32" hose?**
A: I'm sure it could be used, you would have to get the correct adapter fittings though. On another note I would not recommend purchasing. I never installed because the sensor screws into the fitting and is the absolute smallest fitting I have ever seen. I was concerned a bug may hit it and cause it to break off. It appears very delicate and easily broken.

**Q: How do you get the sensor to not leak? I have tried thread sealant and thread locker.**
A: I use TEFLON tape, 3 passes. No leaks

**Q: is this brass or something else? Do I get what is pictured? Derailed 13021? With 6an bard fittings?**
A: The one I got was not brass.  Aluminum or other alloy.

**Q: Thread size?**
A: That is the thread...-6 (roughly 3/8)
