Injector Pump Leaking

My Crystal 8011 has been sitting around for a while. Has started to leak fuel on 2 of the 4 delivery valve holders. I have bought new O rings and Copper washers to install but need a special splined tool (socket or ring spanner) to remove the holders. Does anyone know the socket/spanner size and where to buy from, thanks.

Hi

If you take the delivery valves out you probably will not get them back in.

Hi Mike,
They don't really need to come out. What I need to do is only remove the knurled fitting above each delivery valve and replace the copper washer and rubber O ring. I could try only tightening the knurled fitting and hope the leak stops. The leak is definitely coming from the knurled fitting.
Thanks,
Jim
