Glad I stopped back by, thanks for the lesson, and guess I have some reading to do on this topic.

I have a Mallory Comp 250 pump with a Comp 500 filter + return regulator, and truthfuly probably didn't put all that much thought into it, I just followed the manufacturer's instruction sheet and did it the way they told me to. I really like the return system, and always thought the Gerotor pump was a more robust design than the vane type. Whenever somebody says they've got a Mallory pump on a street car my ears perk up.
