I used an air compressor o blow rust out of my fuel lines and put an octane booster in the gas that i was told would break up the rust for me. Cleanedy filter out and got a huge pile of rust. Hopefully this will solve the issue with a couple weeks of repeated filter cleanings.

Many years ago as I was driving my 71, the speed suddenly dropped to 45mph. 2nd, 3rd or 4th gear, same thing, 45mph. The engine would still sing at 6000rpms with the clutch in. It ran great up to 45, then nothing, no cut-out, no more power. My dad was the riding mechanic that day. Fortunately for me, he knew that it was lack of fuel & and it didn't matter what gear I was in, the engine only had enough fuel to push the car that speed. We pulled to the roadside, pulled the clear filter on the fire wall, blew it out ,yuck!, reinstalled it & problem was cured. I did change the filter that same day. I've shared this because it's possible you may run into this symptom in the future. It may be a good idea to carry spare filters & tools to replace them for a while.

If the lines are bad, my Dad cleaned some in an old truck he had by blowing a heavy fishing line through the line with a compressor. Then tied a .22 caliber wire gun cleaner tip and pulled it through. He had to do it a few times because of the rust but it must have worked, he drove it for years. I'd be scared of getting it stuck myself but you don't necessarily have to use the gun cleaner, maybe something smaller?
