So I haven't had the 900 out in a while and I think air has got into the fuel system, I did get her started although the
engine was surging a lot then after a few minutes running she slowly died and stopped. She has a Bosch PES external drive
pump with attached transfer pump but no hand primer. I got diesel to stage 1 and 2 filters but not to stage 3. Any
thoughts on how best to get fuel through the system again?

I've been known to open the 3rd stage bleeder (actually some times you have to remove it because of a check valve there), and put a shop vac, with the hose connected to the outlet so it's blowing, and put it into the fuel tank, seal it to the tank with a rag or some other clever system. It offers just enough pressure to push the air out and the fuel into the filter. I'm not sure on the 900, but some have the plumbing to shut off and bypass filter 1 and filter 2. The system works well for me, when I filter change my 830CK and my real or Racine built 400. Larry

Bill, greetings from Pa, it has been many years since I have worked on one of the but it runs in my mind there is a small T valve down on the lower filter to open to bypass the transfer pump for bleeding purposes, if the tank is fairly full it should be able to gravity feed , but a little air pressure in the tank should get er going. That filter up high makes bleeding more of a chore.

It can be tough to get the 3rd filter bled. Having the fuel tank right full works best for me - the filter is almost the same height as the tank.
