So many questions...

Get the screws from Ace hardware in Stainless Steel. If they don,t have the exact ones, then you may have to go to Hobart as they do have a shoulder on them. Remember to put anti-sieze on them so you can get them out another day.
You should be able to use a 5/8" heater hose from the auto parts store for the drain line fron the drain valve to the tailpiece. Just make sure you use screw type hose clamps, not the spring type that the machine may have come with.
As I told you in one of our phone conversations, domestic detergents are made to work slowly and they will not power thru the food on the dishes in the 3 minutes it has to do the cycle. There are powdered detergents out there like Commercial Cascade you can buy. They used to sell a powdered detergent in large bags but they can go rock hard if not used quickly or stored properly. You <span style="text-decoration: underline;">CAN</span> install a detergent feeder for a liquid as well as a rinse agent feeder. Ecolab can provide that equipment aand the detergent and rinse agent.
The power feed for the detergent is taken off the first fill solenoid terminal and the rinse agent actually has a terminal on the timer to connect to.
Bubble Bandit won't do in this machine.You can use it upstairs in the domestic unit.
