Ok, We hooked up a water temp gauge, drove it around between 25mph and 50 mph for 7 miles. Temp stayed between 170 - 185 while driving. The highest the temp got was 200 when we were idling in the driveway. When we parked it, I noticed the fuel still percolating in the glass fuel filter (havent changed that yet). Could it just be the glass is getting hot enought to boil just in the filter? Havent had any problems starting it. One pump of the pedal and it starts the first time when cold.
