    I have a pair of 6 CTA’s
    My question is, I want to run 2 micron filters in the Racors, before the filter on the engine.
    I have vacuum gauges and can monitor them and change when needed.
    My reason is ,its so much easier to change the Racors, than the engine filters where there is a good chance to loss fuel prime.

    Good thought, bad idea. You run a risk of clogging quicker than you can monitor.

    If your having issues with priming the last chance on engine filter investigate the following:
