I have an NBFL and recently installed a davefab washer bottle relocation kit. The installation was quick and easy and I was initially very pleased with it.
Over time however, I noticed that as the car heats and cools (both from driving or naturally through the day), washer fluid is pushed out of the tubes and dribbles down the bonnet.
I believe this is because the davefab tank is a sealed tank with no breather.
Do you have this issue? And how would you suggest I fix it? Would you drill a small hole in the cap to allow the pressure to escape?
. If it is that sealed I am surprised a vacuum is not created when operating the washers. Maybe the pump allows the pressure to equalise after a while.
