Threw this together after reading Millenniumtree's PVC canister thread.
I had this stainless tank sitting around that I picked up at a garage sale a couple years ago. I think it was a pressure pot for a spray gun. Built like a tank but light weight, it's new purpose became clear after reading the thread. I only had a hour to do it but I had all the parts so I figured It should be possible.
Barbed fitting 1/4 ID hose 1/4 inch NPT thread
Plastic tee 1/4 inch ID
2 Hose clamps
I think I will be able to EOC down Pikes Peak with this baby.
You can see where I installed the tee, just after the check valve.
It just fits snugly over the battery.
Future additions:
Vac gauge for safety.
Quick disconnect for battery and maintenance access.
Brass tee.
First day testing went very well. I have not run it out yet after many pumps. No numbers yet though.
