Sounds like it's a little on the low side.
Borderline for now, but keep a careful eye on it, and start shopping for a replacement.
I see 15-16 @ idle & 9-10 at WOT.

Scotty's fuel kit will help a lot.
If you have 8psi @ wot, I'd say you're fine. A little below that is OK, just don't like it drop to 1 or 2 for any considerable amount of time.

Yep,
Most FP gauges that you will find rated for diesel start showing the little red warning line right around 5psi. With that said 5psi was the limit a couple years ago, but I hear more and more folks saying that anything under 8psi will require attention rather soon.
