filter is new, but my pressure is reading on the inlet side of the filter, my stock pump was block mounted. I called FASS and he said it sounds like a restriction someplace due to the low FP and the amount of drop I am getting 5psi? I am not leaking fuel or anything but maybe I need to check the pre filter the came with the kit that runs in line, maybe sucking in some air? Anything else I can check?
