Re: 78 Suburban surging then dies on long grade

sounds like you either have a plugged vent on the fuel cap, or the sock is getting plugged from junk in the tank under higher load. also, did you replace the rubber fuel line thats about half way back? not sure if the 70's had it but mine has a rubber flex line kinda under the passenger door area in the middle of the metal fuel line.
