I bought a new sending unit for my gas tank. My old one had just one gas line coming out for the supply. The new one has two. I’m assuming it’s for a return line for other models. So do I fine one with just one line, cap it off or vent it? Thanks

I just changed mine and it had two. When I purchased it before i pulled it the one I got was a single. I would get exactly what came out.

If you can return it that would be best. If you can't, just cap it off.

Thanks Guys
