you can simply add in a one way check valve into your fuel line, as close to the fuel pump as possible, so maintaint he column of fuel in fuel line for faster starting, IF you feel the Priming of pump next ignition start, isn't helping, but this is probably jsut a band auid and the fuel pump may need to be replaced or at least the regulator part (I can't recall on this vehicle if its separate or built into fuel pump).
