Dave, Summer temperatures vary widely due to my proximity to magnificent Lake Superior. Inland as few as 10 miles from lakeshore can often be as much as 10C degrees warmer or colder. While we rarely get many consecutive afternoon daytime temperatures in the 30C (86F). range in July to mid August evenings are almost never this warm. I have central air conditioning in my house and might run it once or twice a summer for a few hours and some years not at all. I never travel down to the lakeshore without a jacket in the evening no matter what the daytime temps have been as a cool breeze can come in off the lake at anytime. Inland however temperatures can be much less variable between day and night and can range up into the high 30's for days at a time. Humidity is not a problem, although locals who have never travel south do complain, and summers while short are usually very pleasant. My experiences driving the Packard in truly hot weather is very rare so vapour lock has never been an issue even in the July 1 parade.
Ethanol in gas is supposed to be 5% by 2010. In southern Ontario I do believe there are some E85 pumps but not here in the north.
One more question about the fuel pump if I may. Should I use any type of sealant on the gasket between the block and pump?
