This is a gravity fed system so hang the tank above the nipples.
Connect the water feed to the float assembly.
The next step is the hardest you will have to fumble through fittings to get the fittings you need. I had to make a 2 washers and used a large slip to thread coupling. I sandwitched the tank opening between the washers. I installed the thread end toward the inside of the tank put on a nut and tighten.From here it is just a matter of reducing the flush opening to 3/4".
Reduce the size of the flush outlet to 3/4"
Connect the flush outlet to the 3/4" PVC with the washer hose.
Cut and connect 3/4" slip to 1/2 T where you want the nipples.
Install 3/4" to 1/8" reducer and install nipples.
Use the PVC cap at the end of your run.
Slice the pool noodles down the side and slip over the 3/4" pipe to insolate.
