Hello Everyone, I recently pulled my grandpa's old Plymouth out of the barn and have been giving it the attention it deserves. He bought it "restored" in 1999-2001 ( he can't remember exactly what year haha). The paint and interior look phenomenal but the engine and drivetrain are original and untouched. It runs and drives but after about 30-45 mins of normal driving it stalls abruptly and just won't stay running. I let it sit for 10 mins and then it fires right up and can make it home. My best guess is that it is vapor locking but I don't know too much about these cars, hence why I joined this forum.
What are some suggestions? I have read about heatshields, risers, and heatwrap. What works the best?
One more question should I install a fuel filter before the mechanical fuel pump or before the carb? I We don't get the best gas around these parts so I want to make sure im not sucking water and dirt into the carb/engine.
Thanks in advance and here's some picture of the car.
