Changed filters and installed new fuel pump. Cleaned fuel line from filter to inj. pump which contained some dirt almost looked.. like it was plugged. There is a good stream of fuel ejecting from the 2 bleeders on the ejector pump. Very little fuel coming out at the injectors. Could inj.pump be plugged (wishful thinking) or does pump need an overhaul. I don't know anything about pumps so what kind trouble will I create by removing the top of the C.A.V. pump to see if there is dirt. Thanks,Udo

Unless the spindles are leaking in the top cover leave it be as the governor springs are connect underneath the cover and needs delicate handling and putting back in the right places,when you open any part of the CAV system it is a right SOB to get the air out,you bleed it up to the two bleeders on the pump finishing with the highest one,keep operating the feed pump till the lever goes limp,with the stop in run position,the throttle on full loosen all the injector pipes a couple of turns each at the side of the injectors,not the top,with a good battery crank the engine over till fuel starts to spurt from the pipe unions,tighten them up and hopefully it will start.
