Midgetracer I think that is my next step, to replace the diaphragm pump with the vane pump and see if the problem goes away. If I remember correctly my Carter vane pump had a pretty high flow rate. I called Carter when I figured out the vane pump was vapor locking and they told me to run a return line into the tank. I told them it was a model A and he told me to tap into the gas cap with the return line. What??!!
