## Questions & Answers

**Q: will this work with the FASS system?**
A: Don’t know mine is on a 3406c cat engine.

**Q: Will this fit the 2008 duramax conversion ? 1r-1750 is what i have on now what is the difference in the two**
A: The one you have on your duramax (1R-1750) is a fuel filter not a fuel/water separator like 256-8753 so it wouldn't make sense to try and interchange them because they do two different functions

**Q: Will this thread onto my stock water seperator/wif 2017 ram 3500 6.7?**
A: No.

**Q: One for $29.11 or buy a 4 pack for $128. That's 32 bucks a piece if you order a 4 pack. Why would i order a 4 pack.**
A: Yes
