I am just going to cap fuel strainer and leave the tubing in place. Looks like you could always sump some fuel into the fuel sampler, then suck the fuel from the sampler to prime the engine, if it was necessary. Checked my CC this morning, very easy to reach up to the fuel strainer area from the bottom of the cowl. Don't see any reason to leave the priming line attached to the fuel system all the time. Just something else to leak forward and aft of the firewall.
