## Questions & Answers

**Q: Will this pump go on neutral when you close the valves?**
A: This pump is pneumatic. The material is pushed in one direct when the air valve is turned on.

**Q: Where woukd i find a rebuild  kit for this pump if i needed one? Any part numbers or kits?**
A: I am having the same problem no parts available as far as I can see I have been searching for hours and still no luck.

**Q: Do you have 3" or 4"**
A: 2”

**Q: rebuild kit for qpk15?**
A: Just because you put a question mark at the end of a statement doesn't make it a question. I recommend looking at previously answered questions. This is a cheap Chinese clone of an industrial pump. If you need rebuilt kits, buy a pump from a pump supply company.

### ⭐⭐⭐⭐⭐ Review
*by F***O on 20 December 2018*

Pump is kind of a cheap unit. Paint not the greatest and instructions are in broken English at best. Saving grace is this thing will pump some oil! I used 1" lines with a 3/8" air line. Best to secure the outlet hose because it is like a fire hose! I am only pumping waste oil and gear fluid, have moved about 1,000 gallons and it has not slowed down yet!
