You know I have been considering what I would want to put on my car.

The problem I am running into is all these leak less pumps is the number of people talking of failures. One of the first experiences with leak less was one that the seal went and the car had to be towed home because the original seal did not function. Seems to me any leak less units you buy you want to consider one you can seal normally too.

What makes it real hard for me to consider the leak less is my brothers coupe. The water pump is untouched since 1970 other than adding packing. Many years and many thousands of miles later all it needs is some grease and the occasional tightening of the seal.

Something to keep in mind. I believe on Vince Falter's website he talks about the shaft diameters. The original shafts were ground to a specific size. Modern replacements are not ground shafts and may be slightly smaller in diameter if I recall correctly.

While I am not saying you should go to the original type. I am going to look hard at the options for a modern seal that also works with the original seal. I am reading the comments and comparisons with interest. I am just pointing out the original is not really that bad.
