Glad you like my bike. I made the tank from an old vacuum canister I had laying around. The canister was used on my S10 drag truck to compensate for the big cam I had in it.Gave me more vacuum for my brake booster.Anyway I got the bungs from The Bung King and welded it up. Turned out pretty good I thought. It's different. Only holds a little over a quart but that's enough for me. It's a toy not my mode of transportation. :helmet:
