1972 Mercedes Benz 280 SE 4.5 Vapor Lock Investigation & Checking Condition of Flexible Fuel Lines

About a week ago, after a long drive on a warm day the car experienced great difficulty restarting after sitting for 15 minutes with the engine stopped. I think the engine was experiencing fuel starvation via vapor lock. About a year ago, I had checked fuel pressure at the fuel rails, and it was around 30 PSI at warm idle which is correct. However, fuel pressure dropped to 20 PSI after engine was stopped for 1 hour. I read an opinion that fuel pressure in the D-Jetronic system should hold and not drop by more than 2-3 PSI after stopping the engine for 30 minutes. This video documents that. I saw a Facebook post of a Mercedes Benz 280 SE 4.5 burning and became worried about the condition of the flexible fuel hoses and injector hoses and seals. I inspected those too and they were fine. Finally, I conclude that the fuel tank is not venting properly.
