I appreciate the recommendations I've been given but none of them are from people who have actually done this on a V10 fuel rail. I don't believe that it is as easy as some may think. I'm being told it's not hard to do but no one is telling me how to do it. Believe me, I consider myself to be pretty well mechanically inclined and if there is a way to get it done I'll do it, all I need is a little guidance on where to start. What I don't need is to be told that it can be done and not be told how to do it. Sorry if I sound a little upset, this whole fuel pressure thing has just really got me pi$$ed. Crimping the return line in a sense would do the same thing as an adjustable regulator. It will restrict the flow and the amount of fuel going back to the tank which should increase the pressure, in theory anyway. The only draw back is that once the line is crimped you can't uncrimp it. What is your thoughts on this?
