Can the tube/hose fittings be changed? How much$$$? I'm about to build a new fuel rail, however I've changed my mind (again) about how I want to do it. Instead of aluminium, I'm going to use steel for the simple reason that heat absorption is much, much lower, helping to prevent vapour lock. I also plan to keep the fuel at high pressure until it returns through the fuel cooler, then will reduce pressure with the regulator located within the cooling shroud over the fuel pumps. My reasoning is that fuel kept at a higher pressure will stay in a liquid state which will transfer heat much more efficiently than a vapour, so will cool better while passing through my fuel cooler, then when it does pass through the regulator which is located inside the cooling shroud, so the fuel will be cool enough to never flash into a vapour as it depressurizes. Then it can be reintroduced into the pump feed line, eliminating the need for a header tank or fuel returns. An adjustable regulator will allow me to increase the pressure as well, similar to what is done in a modern returnless system, however it will still be referenced to manifold press. S.
