Injection nozzles ????

Halli!
Maybe someone can help me again.
And I'm looking for the sealing rings for the injection nozzles (O-rings)
Or, in general, someone who can revise the parts.

Because I tried to start the car again for the first time in a year or more. In short, so for 5 min he also ran (but more bad than right) Then, giant puddle on the ground. (line, hose from tank to filter) Fuel line re-made immediately. After that, 15 minutes. Start attempts. No success. Fuel flow, return run, pump, i.e. So fuel arrives at the front and goes away again.
Then all spark plugs out (looked bad), dried, cleaned and with cylinders 4 and 8 the combustion room was rather a swimming pool. If there is still an ignition spark I control tomorrow (today I had to let it dry first). However, I would still like to have revised the nozzles.
Or can you get the parts where?????? Except now, ebay.
