Never thought of hemp thread. Interesting.....

Well, found the leak. The head developed a hairline crack alongside the input fitting. I must have cranked it down too tight. Sometimes I'm a gorilla and gotta remember things don't always have to be super tight. I got a Racor 645R2 and started installing her today. This time I'm putting it on the vacuum side of the pump. I had to remove the electrical pump and make a new bracket for the filter but it's a better setup this way with the filter also being up higher than it was before. So we shall see how it goes. Hopefully I can get'er done tomorrow or Friday.
