21 From this angle you get a good view of the feed and return lines neatly coming through the body support, to and from the regulator, one above the other. Of course if this were a drag car I'd not be permitted to mount the regulator on the firewall owing to flywheel explosion safety rules. It does make a neat installation though, and allows a short length of braided hose to feed the fuel log. Perhaps too short, as there's minimal flex to allow for sideways engine movement. I'll see how much movement there is when I fire the motor, and may possibly change this hose for a longer, but unfortunately more unsightly, version.
