Brad, I noticed your recommendations for Shurflo pump models on another post. As I research this I am thinking it might be better to run 2 pumps, each running one HSV and two 1.0 mm jets. If I had a pump failure I would still have some protection. In your experience how reliable are the pumps?

I see you sometimes recommend the 239 150 psi pump set @110 lbs. over the 100 psi 238 pump. Would the 239 pump run four 1.0 jets? Or should I run two?

The 239 pump is substantially more $, does it have a bigger/better qaulity motor or is the 238 suitable for my needs?

Cost of the system is secondary, the motor is very expensive and must be protected from meltdown.

Thanks for your help on my system.
