I bought the Comp 110 pump this winter and after talking with Mallory tech, found out it would be too small for my needs. So I will be using that for another build, but I then bought an Aeromotive SS 150+ GPH pump just like mentioned above. It is very quiet and seems to be working awesome. I think either choice of the Aeromotive or the Mallory 110 or 140 will be a great decision.
