Danger

Risk of explosion caused by fuel igniting, risk of poisoning caused by inhaling and swallowing fuel as well as risk of injury to eyes and skin caused by contactwith fuel.

No fires, sparks, open flames or smoking. Pour fuels into suitable and appropriately marked containers only.
Wear protective clothing when handling fuel.

When detaching the couplings on the ME-SFI control unit, detach the center coupling first and when plugging in the couplings, plug in the center coupling D last.

Connect socket box to ME-SFI control unit (N3/10).

Detach 2-pole coupling from the fuel injection valves.

Remove fuel distributor rail together with the fuel injection valves; do not disconnect fuel feed line while doing so.

Plug self-made electric line (048) into the fuel injection valves, one after the other.

Keep fuel injection valves in measuring cups, one after the other.
