In Reply to: 89-90 case 580k running issues posted by jasonf on Tuesday, August 11, 2009:
That sounds like there is a fuel blockage either the filters are plugged or there is a blockage in the line,580K's had two spin on filters and one inline filter between the tank valve and feed pump,I would start at the valve by removing the pipe and making sure that there is a good flow leaving the tank,the tank vent is in the cap and it needs to be clean,with a good flow replace the inline filter before the feed pump,fill the two new spin on filters with clean fuel and screw them on,you now need to bleed the system,open the bleed screw on the banjo bolt at the filters,kick the engine over by jabbing the starter till you have good pressure on the priming pump lever,open the two bleed screws on the injector pump,operate the priming lever till clear fuel comes from the bleeder on the banjo bolt and close it,keep on priming till clear fuel comes from the bottom screw on the pump and close it,finish with the top one,keep on priming till the lever goes limp,loosen each injector pipe on top of the injectors a couple of turns,on full throttle spin the engine over on the starter till fuel starts to spurt from the unions,tighten up the pipes and start the engine,the feed pumps can and do fail,they are sealed units and have to be replaced should they fail.
Case part # for the inline filter D139225,the two spin on's comes in a kit A77470
