I know this is a little off topic concerning f body's but I'm using lots of parts from a 92. I'm doing a v8 swap in an s10 & didn't label the fuel lines when I removed the engine from either vehicle. To make it worse I was planing to go carbed & removed the fuel tank & lines. Can someone give me an idea of the correct plumbing?

 

Use an open end wrench to figure out the line diameter, 3/8 is the main feed line, 5/16 is the return, & then there is the vent line, 1/4 diameter.
