## Questions & Answers

**Q: Does this tank come with plug, filler cap, or o-ring?**
A: Came with filler cap and drain plug.  No gasket at top of reservoir where it connects to hydraulic motor as this is only a reservoir and not a pressure vessel.  Was not deep enough for my pick up tube on my bendpac 4 post lift so I returned.  Verify will fit your requirements before ordering.

**Q: what is the inside diameter at mounting to pump**
A: We have a chart below the large picture with the dimensions for the throat and bolt pattern.

The inner dimension of the throat of the reservoir is 4.7244"

Any questions please let us know.
