While the engine was out I must've caught a leak off connector, it had a chip in the plastic by the 'o' ring.
I sourced a 2nd hand line, that being the 4 connectors and hose.
Still engine out it went in but was awkward to sit the 'o' rings. Anyway with the engine in and started there is some residue around 2 connectors.

I've sourced what are purported to be genuine MB 'o 'rings. A bit fatter than the originals and so harder to sit into the injectors.

I've applied a little petroleum jelly to the 'o' rings to assist in going in.

The easier to access front connector has gone in and locked, with difficulty, but ok.
The second connector has now split the push down plastic part, due to the difficulty of re seating.

Am I missing something?
