Was on the trail yesterday and my rig died on a hill climb. After getting myself up to a level spot I found that the fuel pump wasn't pumping any gas. No filter in between the tank and the pump. Someone mentioned vapor lock but since my tank isn't air tight I didn't think that could happen. Anyway... I plan on replacing my fuel pump as preventative maintenance but wanted to go to an electric pump. What do I need to look for in an electric pump for this beast?
