I noticed something yesterday when I was installing my Amsoil bypass filter. I put the filter in the usual location inside the drivers frame rail using greg from lube specialists mount. There are 2 flexible fuel lines running through the rear of this area. The larger of the two fuel lines, which I have to assume is the supply to the engine, is slightly kinked near the fitting closest to the frame rail. I just had a left side fuel rail assy. replaced which helped my 1093's for now, but I wonder if this kink didn't contribute to the problem especially under load and low fuel levels. Maybe some readers could check theirs for the same condition. I would post pictures but I have no idea how.
