Think I will stick with my Cummins for a while longer. 188K miles and only problems I have run into were a leaky hp fuel line and 2 lift pumps. Replaced the line and leak stopped. Just have to get the Vulcan big line/relocation kit installed to fix the one factory design problem (lift pump location). Heck, the ol blue beast even knocks down decent mileage....best so far of 23.1 mpg on the highway. If she hangs on through the fall outage season, will do injectors, new VP inj pump, clutch over the winter.
