I am the 2nd owner of an all original 81 SWB GMC with a 305. I am experiencing something which I thought was a fuel filter issue. When driving at 55mph plus, I feel a hesitation which made me think the fuel filter was clogged. I slowed down and it would be fine. Some days there would be no issue. Other days, I could not drive faster than 55 without this loss of power. I have changed the fuel filter, Fuel pump and fuel lines and the problem has not improved. I have read and searched the forum but have not found what I need. Any help in pointing me in the right direction would be appreciated
