I'm planning on fuel injection, either an IO-360, IO-370 or IO-375. When building the tanks, I did not add a port for a return line. The fuel selector I have does not have the fuel return function either.
I'd like to avoid a return system if possible. Fuel return lines means doubling the fuel lines, being more weight, double the chance of leaks, double the complexity, more time to build. Seems like increasing a bunch of things I don't want.
The various sources I look at, they all talk about fuel return systems being required or not required for most fuel injected engines. I'm also at a stage that's fairly easy to change. Exchange the fuel selector and add fuel return fittings to the tanks, not that difficult.
What's the real answer. I know there's AFP, Precision, Silverhawk, Bendix and I'm sure other options as well. Which options require a fuel return system? What options come on the standard IO-360-M1B from Van's? What about Titan's IO-370 and Aerosport Power's IO-375?
