1979 Rx7 gas tank help
My 1979 rx7 gas tank (stock) as 4 hose connections on top ...
The rear most one goes to a fitting in a rubber gasket and thats the Fuel vapor valve. Do you have to have this on the car?
I was told the Fuel vapor valve lets air into the gas tank but does not let gas out without it the gas tank will not work
What can you do if you can not find a vented gas cap, and my vent line connection is broken and no good???
I need help badly!

1979 fuel lines
"So with the tank positioned like it was in the car there are 4 hose connections. I'll reference the front most one as number 1 and work my way back.
The first one is the return line and its smaller than the feed.
The second one is the main fuel feed line and its larger and sticks up higher than the first.
The third one is for the cut and check valve and can be capped or connected, your choice.
The rear most one goes to a fitting in a rubber gasket and thats the vent line. If you cap it off get a vented gas cap."

Is this right for the 1979 rx7?
