I just installed a new racor fuel water separator, engine now dies after 10 minutes of running, I pump the bulb and fires right up. My old boat had a primer bulb before the filter, should I put one in there? It ran for a 1/2 hour at the dock after installation. It feels like lack of fuel. when I open drain at bottom of filter gas comes out, so i figure theres fuel in the line, but maybe not enough in the filter can? I did not fill the can with gas when I installed it. any suggestions would be great.
