whats the easiest way to replace this any pics will help exploded diagram or anything i got the diaphram but cant see whats ahead of me not worried just caucious.

 

Not much. Pull the AFC cover from the pump, pull the pin, unscrew the diaphram from the pin, install new one and bolt it back together. It's wise to loosen the AFC boost reference tube from the AFC top so it doesn't get bent and broke.

 

would that diaphram cause fuel to come out of the little breather in the back of the afc

 

No the diaphram won't leak any fuel itself, should be only air in that section. The fuel is leaking from the o-ring on the small pin that rides on your fuel pin. You have to remove the top to repair this leak.
