Their directions are fantastic, tons of diagrams too. Including the very things you mention. Problem is most people do not read them. There's also a ton of videos on Youtube produced by Holley and some of it's heavy influencers.The Holley system needs proper directions on fuel system design, starting, charging, grounding etc. these were the problems I had most when first installing the pro m. When I had mastered the basics, going from engine to engine was easy.
