That tank I initially bought for my Citroen 2CV, I decided to mount it on my Trabant instead. Even though the washer motor is not connected, the hand pump still pulls through it. I still need to take the hand pump apart and lube it to see if it works better. I know others have installed these tanks on their Trabants, does this tank look crooked? It seems the bracket maybe bent? Notice the white funk between my battery bracket and down the side. Hole rubbed in top of battery and acid reacting with the aluminum? Looks better than the 32 ounce poly bottle I had been using.
