Which is the return and feed fuel lines?

[whiteponygt98]

The title says it all. I've converted to carb and all I have to do is my fuel system. I need to know which of the stock fuel lines is the return and which is the feed. One has a bigger fitting and I think it's called a schrader valve??
Thanks,
Brent

By the way this is on my '88 lx, i don't have either of the cars in my sig anymore, it's been a while since i've been here...

the biggest one is always the feed line. by the way how are you going to deal with the fuel. are you putting an adjustable regulator with a return port on it.

Yes I have a malory regulator with a return line. Both lines look to be the same diameter but one just has a larger fitting... Like I said, they look to be the same size line just the fittings are a different size where they attach to the stock fuel rails.

the one with the biggest quick disconnect fitting is the feed line.

I believe the one with the Schraeder valve is the feed line; the other is the return.
