Check out the filters and flex line.


Second that suggestion and especially the flex line. If it is the old original there is every chance it is hard and brittle to the point the interior bore lining is cracked. I had a 54 where a piece of the lining was loose and could be pulled out by pump suction and partially block the inner bore. This resulted in fuel starvation over a certain engine speed. If it is an old original line I would replace it just as a matter of practice. Napa might have fittings but If you have a hydraulic place nearby they can also make one with the proper fittings. If not, one of the PAC regions has repros. There are two styles.
