AFPR/FPD Bypass fitting question

[Justin]

I'm about to put in my new fuel pressure regulator and fuel pulsation dampener bypass... It has those blue fittings on it. Do i need any type of gasket/tape/etc. for those fittings or do I just tighten them down and go?

the fittings should have a crush washer built on it. but if not you will need to use the stock ones. you dont ever need any type of tape to seal it. AN to AN fitting will seal by design. and AN to to a tapped hole will need the crush washer.

Crush washer or O-ring; make sure it is a gasoline compatable o-ring though.

Thanks guys.

Can the crush washer be re-used, or should I pull it off (assuming its there) and just reuse the copper o ring on there right now? Its pretty new (the copper one)

Ive never had a problem reusing copper or aluminum crush washers
