This new girl has a problem!

[jmedero]

I was vapor locking on the power tour last year. My tank on my nova just needed to be vented better. Some fuel line and a filter on the end and boom. Did the last two stops of the tour with no problem. It was in the 110 deg range those days.

I had the same issues. took off the rochester and put on a edelbrock. Still have some issues when its over 100 but not as bad as before.

Hello everyone. Took me a little longer to get on the forum than babydoll but I'm the boyfriend. Thanks for all the suggestions. I replaced the thermostat with a 180. (apparently 185 no longer available) Of course now the weather has broken so we won't have hot enough weather here to cause an issue any longer. ha ha ha Anyway, vapor lock is very common with mechanical pumps and carbs due to low fuel pressure. Idling in hot weather in traffic is the worst. Insulating the lines is about the best you can do. Thanks for all the helpful tips.

Welcome to the forum. You will find this is a good place to get help with the problems that happen with these old trucks.

There are some very helpful people here that are always willing to assist with any problems. I have learned a lot from many of them in the years I have been on here.

Hope everything works out with the problems. I was having heat problems with my '71 with a 454 and stock carb. Since we are building a '67 swb stepper with the same engine we are doing some upgrades that should help including a mini starter with remote solenoid and a new Holley carb with a phenolic spacer under it.

I am sure liking the cooler temps, we turned off the a/c. Heck even had to wear a long sleeve shirt this morning when I first went outside.

Ask any mechanic from the age of carburetors and he will tell you it works. I not only gave you the tool, I provided an explanation as to why it works. The other theory is that is acts as an insulator and protects the line from the surrounding heat. Either way, it is an inexpensive easy tool to help in diagnostics. If it fixes the problem, you know you have a vapor lock issue and you can proceed to resolve it with a more permanent solution. IE check fuel pressure, re-route the fuel line etc... etc... etc...

Even though you were being a smart ass I will answer your ridiculous question about new trucks in hot climates, Obviously clothes pins on the fuel line was not an option. When these trucks were new off the line they did not have weak fuel pumps, re-routed fuel lines or any number of other changes that may cause a vapor lock issue. Seems to me you are the one who needs to "show some professionalism."

Now boys! No need to fuss, please! My boyfriend had also heard of this diagnostic idea. Believe me, all ideas are welcome and appreciated!

That is amazing, Joseph! Thank you for sharing! We will, of course, be painting the top of the cab white.

Welcome to the board Babydoll and MacGyver72!
...and COOL truck!

Oddly enough, we are seeing a lot more vapor lock, even here in Seattle.
I would think current fuel mixes are aggravating the problem...
the boiling point of alcohol is way different than gasoline.

And yes, clothes pins will help pinpoint the problem. I prefer wooden ones.

And Babydoll, don't mind the boys...just think of it as having 85,000+ big brothers.
