Getting to this post a little late as i thought the BB was kaput. Glad to find otherwise. Although I see you've purchased a RockAuto fuel pressure setup, I've been using a Harbor freight job for years and years and it's worked very well. In fact there have been times when I duct tape the gauge onto the windshield so when I'm driving around (for testing purposes only!) I can monitor fuel pressure. This came in handy one time in Florida when I was able to verify that my in tank pump had died.
Anyway, be careful of the connections, maybe use Teflon tape because I've always had leaky connections and have wrapped a rag around them just to make sure they don't squirt if they do leak.
Rota of ruck.
