1968 Dodge Dart GT Sleeping Beauty?
Quick update. I have been to two shows. I trailered it both times due to the distances and having very limited time on the Dart. The new fan solved the engine temperature issue. More coolant also made a big difference.
The vapor lock issue, I believe was more of a vent issue on my gas tank. I was looking to solve the problem by using a vented gas cap. One of the guys at the car show on Saturday pointed out that was not a very good way to solve a problem. I went home, pulled the vent line off of the fill tube in the trunk. I blew it out. The restriction on the tube is at the flare on the rubber 3 inch connection. I tapped it out just a little bit bigger with a drillbit. Now I can run it and immediately check the gas cap. There’s no pressure you can sit the Dart in the sun and it still doesn’t build pressure.
As the Mopar fanatic explained at the car show, the fuel pump may be pulling 5 pounds on a good day and it’s trying to pull against the gas tank. It’s a losing proposition, correcting the gas tank pressure problem pretty much the way the factory intended it to work really seems to have cured everything.
Another highlight today other than spending time with my lovely wife on a 16 mile bike ride, was having my oldest son take the car and go to his in-laws for dinner and then back home without having any issues. 3 years were worth it all with just with that one thing
Next weekend is a pretty good car show that I love going to. It’s all old stuff 81 and older and I am driving that car. The car trailer is staying home. Wish me luck.
