Sending unit question

[BornNaked]

Hello fellas,

I will be replacing the gas tank on my 1974 dart sport. I'm on rock auto and I'm confused by the measurements of the options. How do I know know which one to get?

Thanks in advanced!

Whatever you do save and re use the old lock ring! The new ones are to thin!

I'd get the 3/8 outlet and a known brand. The less chance you'd be starving for fuel.

I would get spectra 5/16 with or without return depending what you have. That would be best stock replacement

Get one with a return . You'll need it with this ethanol fuel. Even if you don't use it for now and cap it. It will be there once you run the line back from this style filter.
