It looks like it might have fixed the issue. We went camping last weekend and towed in the mountains with no issue. I was accelerating up the hills with the A/C going and had no codes thrown. The real test will be in August when we go on a 2 week camping trip.Any Updates Just Threw a Code Low Rail Pressure did this fix your issues
Doubtful you'll get any responses from a 4 year old thread.Going through this on an '08 right now. Appreciate the tech write-up.
I find I'm not thrilled with the supply line to the filter housing, but one factory clamp (these are just spring clamps) is buried under.....a manifold for which I don't have the proper nomenclature -- something for the IC.
Suggestions on how to disassemble said manifold? It appears I could try to split it vertically at a 4-bolt plate or remove from engine --- the latter actually appears easier but I'm wondering what gaskets I'll need on hand for proper reassembly?
