So I know I'm late to the party here, but in the interest of helping others out I can tell you all you need to do is type "12 volt low pressure fuel pump" into your favorite multinational online supplier of choice and you will get several options. This is what I did when my fuel pump gave up, 30 bucks and one day later I was back in business.
Your fuel pump may have dirty contact points. They are similar to the ignition points in pre-electronic vehicle ignition. That is what was wrong with mine. Pull the black plastic cover from the pump (one screw) and clean those points with emery cloth or equivalent.
