I would change things a little bit
1. Heat strike water in BK
2. Pump into MT
3. Heat sparge water in BK (while mashing)
4. Pump sparge water to HLT
5. Drain first runnings to BK (start burner on BK)
6. Pump sparge water to MT from HLT
7. Drain 2nd runnings to BK
8. Boil. Cool.
9. Pump wort to fermenter.
This way you can start heating the wort in the BK while sparging so when the sparging is done the wort is almost to a boil saving time.
Also I would suggest brewhardware for the pump, fittings, hoses etc. The chugger center inlet works well for me.
Thanks for the tips. Will take a look at the site.
