Hi guys. I've got a lhm leak somewhere around the lhm tank/ doseur valve area (the car's lhd so the doseur valve's on the other side).
I need to move the lhm tank cos I just can't see where the leak's coming from. I'm losing 200ml every 200kms so the leak's now quite bad. When I remove the lhm tank to see the leak I can't run the engine!
I'm thinking of just extending the pipes temporarily but need to know if this will upset anything. I can't see why it would, but would be grateful for any advice.
Thanks!

I can't see a problem except you may get air into the pump feed pipe so fill it with fluid before you connect it up again.

Under the LHM tank there is anti-sink valve. The end seal might cause this leak (see pic).
It can be seen without removing the tank.

My first thought too - it's the green seal. Be very careful how you fit the replacement; it's easy to pinch the seal as you tighten up the screw-in cap.
