Hi,

I first want to thank you all for your help. I own a 1965 Ford Mustang, V8, automatic. My engine has 16K miles from restoration date. I'm using an edlebrok card and intake. I drive my 1965 to work on occasions my commute is 44 miles highway and during hot weather my stang sputters when I'm stuck in traffic, but in normal weather it runs fine. What can the problem be?

Thank you,

Gus

You may be having some vapor lock going on. When the car is in motion the heat from the engine is being removed. When you are in traffic or standing still the heat my be causing vapor lock. You need to shield the gas line or move the line from excess heat from the engine. If it is running close to the exhaust or laying on the intake manifold it could be picking up heat. How hot is the weather when this happens. Does it do it in the cooler weather all so? Check your timing also to make sure that you are timed correctly. Good luck on your problem.

The temperature is around 90 -95 f degrees(Los Angeles, CA). Also I have no carbn spacer. The glass gas filter is near the intake.

The car runs good in cool weather. How do I shield the gas line(rubber.

They make a carb spacer that is made out of phenolic which are good heat shields. Also it would not hurt raising the carb up a bit if you have the room. A 1" rise to a carb is a good thing. Summitt Racing has a good selection of spacers. That is a cheap way to go. It sure sounds like vapor lock. Give that a try.

Just move the gas line a way from very hot places. Also the glass filter may be a problem as the glass attracts heat. Try using a different filter and see if that takes care of the problem. Only change one thing at a time so you will know what fixed the problem. Is your gas line a regular metal line? They make so nice gas lines out of stainless steel wrap over rubber. They look real sharp on the engine. Thats what I have on my 69. I also have a carb spacer/heat shield.

The gas line is rubber then glass gas filter then rubber going to the carb. I'll change the gas filter, then I'll add the carb spacer. Thanks
