| Plug connections | unplug, plug in. |
| Anti-twist lock (12) | pull off at injection valves, fit on. Anti-twist lock must engage in four-sided lug (arrow) at injection valve (Y62). |
| Injection valves (Y62) | withdraw from fuel distributor, insert. |
| O-rings (14) | replace, oil slightly to facilitate installation. |
NOTE:
As of 09/92 modified injection valves have been used. The fuel outlet (a) has been converted from 4 to 2 holes to achieve improved fuel preparation.
As a result of the arrangement of the holes, 2 jets are formed when the fuel flows out which spray the fuel in the finely atomized flow onto both injection valves.
