Hello. I'm just getting started with HHO application in my vehicle & I'm wondering where to get supplies. My wish list includes plastic mason jar tops, materials to tap into the jar tops for gas recovery (not sure what these are called), inline check valves, binding posts, basically all of the things that I can't walk into a store & get...keep in mind I live on Maui so supplies can be tricky to find. BTW $4.18 for regular. I hope I can get this system going soon. Thank you for all of your support. Aloha.
