I am going to change water seperator filter on twin 525 sc's. Any tricks or tips?

Don't smoke

Refill the new ones about 3/4 of the way with fuel before you screw them on. It will save a lot of cranking time when you restart it.

My plan is to just unscrew it fill it 3/4 full of gas then reinstall new. Did I miss anything? Do I have to do anything to gasket? I know my buddy changed his a few months ago and had a problem with vapor lock. Anything I can do to avoid that from happening?

run motor's for awhile after change to get all the air out of the line

Make sure the old rubber gaskets come off with the old ones...check flanges with your finger...dab a little oil on the new ones and hand tighten...don't have to f with priming the new filter...it will purge instantly...have extinguisher near by for safety.
