Guys, here's a thought that may work for you, I'm doing it on my V-6, although the sizes will be metric vice SAE. I purchased 20 feet of #6 or 3/8" and #4 or 3/16" stainless steel tubing for my fuel injection system on the motor. I have a tube bender and a tube flaring kit, both fairly reasonable to purchase. What I'm gonna do is bend the tubes to fit, flare them and put flare compression fittings on the tube ends. Fuel injections systems run higher fluid pressures than a normally aspirated engine does, in the 40-70 psi range and there is a continual flow, normally from the fuel rail back to the fuel tank. The only place I will not have a tube fitting, hopefully, is where the standard fuel lines on the engine will be hooked up via a pair of hoses. I hope to get the newer style hose connections from the auto parts store if available. HTH.
