Hey guys, finally got the new rear end in on my '71 El Camino, aligned, pinion angle adjusted, new brake lines made, and drag bar installed. Been doing long break in drives to work (put 150 miles on it in 2 days).

Basically this is what I noticed. Filled up my gas tank before driving home (about 40 miles the backroad cruising way I like taking), and by the time I got home, I usually do a quick look over of the car and noticed in the back under the gas tank a shiny pool, and noticed it was fuel. Get under the car and found my Tanks Inc. rollover vent valve had a trail of fuel leading down the vent hose and to the floor. Heres the pic



Heres how I have the fuel tank set up. My fuel tank has the obvious fuel sender to my carbureted engine with a return, and this particular tank has 3 vent valves on it. I plugged the outer 2 and only have the inner center going to a vent valve that is higher than the fuel tank. My question is do I need 2 other vent valves to each other vent? Does this vent valve need to be higher? Ive never noticed this issue before. Thanks!

The entire vent hose needs to be higher than the full fill fuel height in the tank so that fuel slosh drains back to the tank rather than being blown out the valve.

Fuel slosh out of the valve shows that the valve may not sealing, it is intended to prevent leakage from the vent in case of a rollover. But since you haven’t rolled the Elky the valve is not going to do that because there is no weight of fuel to press the valve closed when the vehicle is standing on all four feet.
