Highway driving at 65 and 70 mph, when you start up hill it starts surging and loping along. It will eventually recover when you crest the next hill. This happens with just the weight of the truck and extra engine load from climbing the hill I'm thinking fuel filter or pints and condenser as it has the Rochester 4 barrel. Any other suggestions would be appreciated
Fuel filter at the carb, is there and inline filter along the frame rail?
