For sale is a Carter Super Speedway mechanical fuel pump for a small block Chevrolet.  We took this from a running engine that we parted out in our shop.  It has -10an screw-in fittings in and out.  It puts out 6.5-7.5 psi and should not need a regulator for a gasoline application.  In guaranteed good working order.   Thanks for looking and as always I combine shipping when possible.
