I got the C-rail all blueprinted. CNC'd two brass fuel pressure gauge adapters and silver-soldered (brazed) one in the C-rail. Transferred my adjustable fuel-pressure regulator to the new rail. Have everything in-house and pre-made to do a 2nd one but finding another C-rail could turn out to be a tall order. Time will tell.

Going to install it after a quick bite to eat then and see how close I've been at "guesstimating" fuel-pressure the last couple years.
