DooWacka, wanted to let you know that thanks to your help I was able to isolate the HighFlow pump I received and bench test. It was in fact not developing sufficient pressure. I contacted Axiom Performance (HighFlow) and was immediately shipped a replacement pump. I installed it and it works perfect with a very manageable current draw and the required pressure. The customer service at Axiom Performance is outstanding and they seem intent on continued improvement to offer the best pump possible for this difficult DI application.
