Why do today what you can do in the middle of the night? Last night, I decided to hook up the fuel pressure gauge in our new truck. Not a bad idea in itself, but the fuel pump chose that exact moment to die. I couldn't be happier, since it forced me to replace the fuel pump (cheaper) and discover that the injector pump (rather more expensive) seems to be just fine. I should learn better than to trust malfunction codes from computers. I discovered that the replacement part could be had - cheaply - from the Dallas office of Cummins Southern Plains - at the late hour of 10:30 pm! So... I trekked down there and got one. I muttered to myself as I pulled in to the garage, "I should just go ahead and swap those out. It shouldn't be too bad." And it wasn't. Note to self: When changing fuel pumps, put the fuel tank on the downhill side of things. I think I still smell like diesel.
