JrJohn replied, and I thank him for that, but did not extend a reason as to why it won't work. Has it been tried? Does it hold too much pressure? I just thought I'd throw it out there before I try it.
I assume your talking about putting a one way valve in the preasure line from the exhaust? if so, I don't have to tryit to know it won't work. I can guarantee it won't. As soon as you put preasure in the tank without a regulator in the fuel line you will totally flood your engine as soon as you shut it off, not to mention eratic running. you'll never be able to tune the engine to run right at all rpms. Once you have a preasurized system, you need the preasure to be constant, it can't be without a regulator.
Your trying to reinvent the wheel, Trust me on this one, If you need pics of the set up, I'll send some
