Need a little help tracking down where we can find a hot air choke tube for my sons 1978 K10. Ours is beyond repair. Can anyone point us in the right direction?

Thanks!
Joe

Those are heat risers. I think he is talking about the hot air choke tubes that run from the top of the carb to the insert in the exhaust crossover in the intake, then from there into the choke spring housing. My 1980 has that setup. Which tube is bad? The part that goes into the intake or one of the tubes? An electric conversion kit is only $50.. it might make more sense to get rid of the potential vacuum leak and hot tubes right next to fuel lines
