My 1428 just started running weak maybe good engine power to about 1300-1500RPMs after that it sounds like it is starving for fuel. I have tried to bleed the air out the system at the fuel filter, injection pump and at the injectors.
The first two appear to be bled okay but I get just a little bit of fuel at the injectors. I would think that I should see a fair amount of fuel at pressure at the injectors. also I only have 80hrs on this machine.
TIA for your help

Is it possible that your filter is dirty??? Or anyone touch your fuel valve that is close a little?? Is it possible you hit anything that compressed a fuel line?? Keeep investigating, good luck

Roger, I checked the fuel filter and that didn't work so after some thinking, I haven't had to troubleshoot in awhile, I pulled the air filter and she rev'd right up so it looks like a new filter is required. Now if I can find one other than the dealer.
