What crush washers, O-rings, etc needed to remove and check a Cold Start Valve?

[Larry C Leung]

Collective,

Looking to have what I need on hand in advance before I test 
my Cold Start Valve. So, what do I need in terms of consumables
(i.e. crush washers or O-rings) before I do the job? 
Likewise, I MAY have to replace my Warm-up regulator, which has
two SS fuel lines running to it. What size crush washers do I need?

TIA,
