I have an older edelbrock 1406 carb that i am thinking about swapping out for a new avs2 1906. Its a mild 350 with a mechanical fuel pump.(carter) used mostly for cruising and the occasional red light stomp. I have read the avs2 like to run lower than 6 psi. Wondering if I should run a fuel regulator or are they more for electric pumps and Efi?
