For what it matters, I had this problem with my 79 T2 loaf. It was
especially susseptible to the bucking and starve mode as the tank got
emptier. Wouldn't do it on a full tank regardless of other conditions.
After fuel pump R&R, filter R&R, and some class B profanity, I took the hose
off at the tank spigot and found an inch and a half long sliver of a rubber
type gasket material in the line and could only guess that as the tank got
lower, this piece in creasingly blocked fuel flow to the pump and engine.
After removing(and flushing another couple gallons out for any other grunge
in there, I had no more problems. have no idea where the rubber came from
unless a devious troll from Mt. Horeb sllipped it in there.
