having trouble with my fuel. I have fuel at my rail but no start. I did go with a walbro fuel pump and a fuel pressure regulator. As i was messing with the return line that comes from the fuel rail and if i bend the hose to where only some fuel returns, it fires right up. Just doesnt hold fuel pressure. Any ideas?

If youre not maintaining pressure at the rail, I believe that points to your regulator. You answered your question, when you pinched or restricted the return line a bit to success.
