My memory is fuzzy on those year engines and fuel pumps....

But, is that one that has the level actuated by the revolution of the cam?

If so, due to age, you could experience wear on the cam lobe which will impact fuel delivery.

BTDT with an AMC 304. I want to say the 258 has a similar setup.

Remember:
Jeep = Just Empty Every Pocket and you will have Just Enough Extra Parts.

and, you can say - Fix It Again Tony
