points out a potential problem for the last injector in the rail:

* The injector on the furthest end of the fuel rail(s) in a returnless system may be more prone to dirt contamination and clogging than injectors further upstream. Because there is no circulation of fuel back to the tank, the end of the fuel rail may become a sewer pipe and collect any debris that gets past the filter. The debris may clog the inlet screen in the injector and starve the injector causing that cylinder to run lean and misfire.

This is part of why I was recommending a loop style setup, regardless of if you go return style or not. I'm going to release some pics in a month or so of what I'm going to try out. But, in the end, I really think we're going to need more fuel pressure, which will require something to be done with the pump....
