    Long story, more to post later -
    I'm having to replace a fuel line from stbd tank to racors. The line being replaced is the one that goes from selector valve to the racor filters
    What's the best way to draw fuel through the new line and purge the air in the system?

    Maybe -
    I would think it would take forever - it's a very small pump

    When I do my fuel side service, if the fuel valve is not closed, when I open RACORS housing lid, the fuel will keep flowing. I can't say for sure, but based on my understanding, the fuel should flow through the line naturally to the RACOR. Then, use the manual pump on your engine to purge the remaining air from the system. It usually takes 30-60 seconds of manual pumping.
