need some advice, running 3/8" fuel line, how to run, what to use

I'd check to make sure none of the lines are at, or below, the lowest point of the "frame". Kind of looks like a small problem in this photo. View attachment 1715214172
Ya know, it's right at the frame rail, but not lower.

This is where I'm at right now, coming off the fuel filter going into the dual feed carb line. Is it okay if I come off the back of the feed with a 90deg. fitting then go into the fuel pressure regulator?
