I had two Holley techs tell me conflicting information but we finally decided on the fact that the carburetor does need a regulator at the pressure my pump puts out. So I am putting on a regulator and after talking too them for a while I am sending this 750 back and getting a 770 with vacuum secondaries and its actually cheaper.
