The tank came off of ebay:http://www.ebay.com/itm/round-gas-ta...0AAOSwoudW9Cau
$50 incl. shipping. Not bad $$ and fast shipping. Comes thru with gray primer. Very happy with it.
The dual brake lever/throttle assembly:http://www.bicycle-engines.com/Dual-...ottle-Kit.html
$20 incl. shipping. Excellent build quality. Made of METAL instead of plastic like the kits have, and it works perfectly.
