Interesting it say no pre-fill on the filter. Is it a Baldwin? I noticed on Baldwin's web site they say "see OEM recommendations" regarding pre-filling or not.

We concluded the 12 valve engine doesn't have an electric pump, so nothing will happen if you turn on the key and wait. You'll have to prime manually with the lever nat_ster and others wrote about, or prime with external power with low-pressure air as bansil described, or prime with starter motor power by opening an injector line.

The fuel system recirculates: a pump draws fuel out of the tank, pushes it through the filter, then into the injection pump. But that's not the end of the line. Whatever fuel the injection pump doesn't use is returned to the fuel tank. Air purged from the filter follows the same path: either through the return line back to the tank, or through the injection pump to the cylinders.

You're almost there; just half an hour (or less?) left to go!

ok ok heres my plan

I just put 10 gallons of fuel in, when I hit e and fill her up she will usually only take aprox 45 gallons. It says on the fuel door my bus has a 60 gallon tank so I put enough lucas fuel treatment in for roughly 25 gallons. heading the wise words of bansil im going to drive somewhere im not worried about being towed for a while and attempt this there

Sorry.. weekend was so busy I had to neglect everything else. I wouldn't expect the Lucas to be related to the no-start problem; it ran fine with the Lucas before changing the filter?

If it won't start it's almost certainly because there's trapped air preventing the pumps from injecting diesel into the cylinders. My suggestion is to run the manual prime lever a while longer, test again whether it starts, and if not then proceed to bleed the air from the injector lines. Summarizing what's already written on that: loosen the nut and crank the engine. You should be able to see the change as bubbles decrease, wetness increases, and spray distance increases as the air is bled from each line.

Edit: odd coincidence... a rental customer showed up a few minutes ago with the towable air compressor with the Deutz engine I've mentioned here a few times. Said it wouldn't start this morning. After a couple minutes of troubleshooting I asked whether it might have been run out of fuel. He said it had gotten pretty low, but the tank wasn't dry when he re-fueled... so I grabbed a wrench and proceeded to bleed air from the injection system just in case. Sure enough, that was it. After just a few cranks with the #1 tube loosened it started stumbling and sputtering. I had to run the starter a few more times as I continued bleeding injectors #2 and #3, then another pass through them all just to be sure, but it was probably 5 minutes total from beginning the bleeding to engine purring like normal.
