Well, I can put a regulator on it... I just don't want 20+ lbs of pressure coming out of the pump. I just found a Stewart Warner exterior pump that has a 48" dry sucking capability so it will self feed well..I just don't know how noisy it will be. I have used Carter and Edelbrock Mechanical pumps but they don't seam to last too long 2-3 years then they don't work any more.
