Hi all,

I've got an 86 SDL and she always seems faster after I top off the tank. I have the same seat of the pants feeling on my 2001 dodge cummins. Does it maybe have something to do with increased fuel pressure? Less strain on the pump?

p.s. I had my injector nozzle o-rings fail recently. Im assuming its due to ULSD and I have not been putting in any powerservice. It would not want to start without a few minutes of cranking. I thought it was glow plugs but they worked fine. I guess too much air in the lines.
