F250Thank you for your input will start there i was also told that it could be carburator needs adjusting or possibly a vac leak any thoughts on this?

Hello All!!I have a 78 F150 Trailer special. Truck idles fine. It has a problem when going up hill like its running out of fuel and will not climb, it will not pull itself. when you first jump on the accelerator it hesitates on flat ground, but then runs out fine once past the hesitation...
