Default fuel line feed size

Simple question (I think) that I can't find the answer to-
What is the inside diameter of the fuel feed line on a 2001? I'm considering using the stock feed line as my fuel return line on my new fuel system install, but I want to make sure its large enough to handle the flow.
Thanks guys!

From what I've found 5/16" is the factory return line size (not the feed). It looks like the feed may be 3/8", but I'm looking for the INSIDE diameter.
So, if it is 3/8", is that the ID or OD?

That is always ID. 3/8" ID feed and 5/16" ID return.

I used the factory 3/8" feed line as a return line on my 650hp camaro without a hickup.

Thx for the clarification! I just wanted to make sure I wouldnt overrun the return side with my twin pumps. I ran the stock return with no problems at ~650whp, but my setup has changed significantly now.

Apologies for dredging up a years-old thread, but I just want to correct a bit of misinformation. Hose is generally measured in ID, and tube is generally measured in OD. I just measured the diameter of the nylon tube used for the stock feed and it is 3/8" OD.
