I was wondering, if you got a windscreen washer T section as in picture and connected your spare pipe on to one of the other pipes, like the fuel flap for example.
This might result in halving the “suck” to the fuel flap and the markers but the both might still work ok.

I think your idea is worth trying.The only problem is i dont know which pipe is for the fuel flap.There`s FKS,SFG and ZV.Please advise if you know which one it is or if someone can please tell me what these letters stand for.

That, I don’t know but disconnecting one pipe at a time should eventually hit the right one, you would have to temp. block the hole (Bluetack perhaps) that you remove the pipe from otherwise the pump may not “suck” as it should on the 2 other remaning pipes.

Don’t know if that idea of the T fitting will work, just a thought really.

fks = rear head rest release

sfg = trunk lip closing and chrome handle thingy

zv = central locking

i`m not sure how t-ing into the central locking would help, but doing it with the fgs would work if you pressed the switch.............

Ah I get your point now Alexander, he would have to operate a switch first, never thought of that.
