Any advice on the following problem:
280sl in storage and not run 5 years; electric fuel pump runs, provides plenty of fuel to cold start injector, and fuel coming out of return line to tank. However, there is no fuel exiting the top of the injection pump at each fuel line union connection. Thought it might be the injection pump ball pressure valves for each line; could they be stuck? Don't have the extractor tool (MB 000 589 623300 or Bosch EF 8117A) to take out and clean the ball valves. Think this might be it? Any idea where I can buy the tool noted if my guess is correct?
