So, I recently put an M3 E90 replica bumper on my car as the old OEM bumper was toast after 12 years.

The problem with the bumper was that the spigots on top leaked when I filled up the window washer fluid reservoir.

1st, the line that connected the spigot to the quick connect was too big for the spigots fitting.

I replaced the line with 3.5mm vacuum line..

2nd, the quick connect did not have an O-ring.


I had to find an O-ring in my o-ring supply that I bought on Amazon a little while back for another project on the car.

3rd, the line connecting the spigot to the washer fluid system did not have a 1-way valve, which keeps the fluid from leaking out of the top mounted spigots on the bumper.

After researching no 3 above, I found a post where a guy listed a part number for used for Mini-coopers, which is a one way valve used specifically for this purpose. So, I thought I'd give it a try.
