Stock fuel line size on 2003?

What size fuel line is on a 2003 Chevy 2500HD duramax? Also what kind of material of fitting do you recommend to hook up a lift pump? Would stainless be the way to go? I am hooking up an edelbrock 1792.

hmm....I think its 1/2" line. I'm pretty sure you could just use standard brass fittings.

I was thinking it's smaller than 1/2", it's been so long since I hooked mine up I dont remember off hand. Brass, aluminum, stainless is all ok. The ones on my Chevy are Brass and the ones on my Ford are Aluminum, not a single problem from any.

Dont quote me on the smaller than 1/2" part since I dont remember for sure, just what I was thinking. I know the return line is smaller than 1/2" for sure.
