1990 Zephyr 550 California emissions style gas tank

Postby Old Kwack » 17 May 2020, 13:54

Hi, I purchased a replacement gas tank for my Zephyr 550 (thank you DaftRusty) that has the 2 extra vent fittings on the bottom for the California required emissions cannister and separator. Since my 1990 Zephyr is the 49 state version, how do I plug the extra vent fittings? Will a simple rubber plug suffice? Could I run a rubber hose from one to the other looping it around or do I need to run it to a PCV type one way valve? By plugging it am I affecting the pressure/venting in the tank? Sorry if this is a dumb question, but I'm not much of a mechanic. Thanks, -Dan

I just now saw this......use quality rubber plugs exactly like the vacuum plugs on the carbs. Other types of plastic or rubber plugs will become brittle from exposure to the gasoline fumes.
As long as you reuse the locking gas cap from your other tank, it will have the pressure equalization ports (vent) built into it.
