Last weekend I had a terrible time when the club went to Boulder, CO. Temps in the 60s, boiled fuel after almost every stoplight. I was able to avoid big trouble by toggling the fuel pump switch. When I got home I finally gave in to some scientific testing.

Using an infrared thermometer, I discovered that when the fuel was boiling, the temperature at the primary inlet was 99.7 degrees, secondary inlet was 117.7! I finally gave in and completely insulated the fuel lines all the way to the carburetor. It was in the 70s Sunday. Went on a long drive with a lot of stop and go driving. It didn't boil at all. When I got home to check the temperatures, the primary was 93.8 and the secondary was 92.8.

The wife doesn't like the way the fuel lines look, but at least we didn't have problems Sunday. Tomorrow, however, is another day!
