Sorry missed your post last night.
Per the last gas tank pic, he is referring to the brass fitting next to the fill hose, he's asking if the part of the brass fitting inside the hose is a hose barb ( just like whats sticking out) or if you stuffed a threaded end inside a the hose and clamped it down.
Per the belts, i run one belt to the power steering and crank pulley, one belt on the crank, water pump and alternator pulley's. this is the standard belt routing.
As per the carb, there is an adapter plate you can buy that's suppose to work for the chevy truck by clamping to the throttle lever, i don't have one tho. lots of auto parts stores and places like Jeg's carry a bracket to mount throttle and kick down cables on.
