If you have a bad vapor canister purge valve, the symptoms that you experience will potentially be worse than the symptoms of a bad charcoal canister. If it does, change the filter before doing much more. The vapor will just sit in the charcoal canister until it is needed again. Check to see if the carb on your 6 has the same type filter set up. I had a '67 Mustang (289 V8 w 2 bbl carb) and there was a small fuel filter that screwed into the base of the carb and the other end connected to the fuel line. Check with your auto supply store (NAPA, AdvanceAuto, etc.) to see what they have and recommend. The other solution to handling high temps is to wrap the fuel line with a covering usually metal. Higher pressures deminish vapor lock (which is why it is not an issue with fuel injected modern cars) and if this is a new problem it could be a sign the fuel pump is going. Since you are not reporting extreme temps your fuel pump maybe failing and not producing enough pressure.

Vapor lock is both pressure and temp related. If the cars starts and runs normally after the water treatment you have pretty much confirmed vapor lock. The carburetor has Holly stamped on it so I’m guessing it’s the original as most of the stuff on the engine seems to be original.To test for vapor lock pour cool water over the fuel line that runs from the fuel pump up to the carb. True/false? I’m not finding any compatible 2 barrel spacers that aren’t aluminum.

I might have the mechanic do that.Ĭan anyone recommend a compatible carburetor spacer and tips for installing? From what I’ve read here if insulation is the goal, a phenolic is better than aluminum. I tried to do the thermostat myself but I couldn’t get to a bolt (lower right) without removing the A/C which I don’t want to do. I’ve been told replacing the 195 degree thermostat with 180 degree and a carburetor spacer will help. The theory is the heat from the engine I guess builds up while the engine is off and the fuel evaporates in the carburetor before it gets a chance to ignite. Worked well, I needed to purchase a second one because the first wasnt long enough. But if it sits for more than 5min I have to crank the starter for 10secs or more before it finally starts to catch. Used this to thermal insulate the fuel-lines of my 68 Mustang to prevent vapor lock. It even seems to start fine if I stop just briefly (5min). On the 1968 302 2V Cougar, when it’s running for awhile and I stop for longer than 5-10min it’s really hard to start. Based on my symptoms I think I’m experiencing Vapor Lock.
