Don't usually like to revisit old Topics, but this Tap came back to haunt me.
I started dripping fuel out of the Tap and apparently emptied the fuel out on the floor probably over last winter.
Having concerns that my workmanship, or the materials I had used were at fault, I took it back to find the cause.
Glad to say the bits I did were not faulty, but found the fuel was leaking out of the lever end.
So I stripped it down on the understanding that if I can't fix it, they will have to replace the whole unit (if they can find one).
Talk about over engineered!. Seven separate parts just for the tap lever control !, including a plastic type seal which had dissolved/rotted which was causing the leak-
So as usual, I hit the challenge and went for making a replacement seal from fuel resistant 1.5mm thick nitrile/nylon reinforced rubber.
I had to make 2 special punches that could cleanly punch through the tough layers and in the correct positions-
Glad to say that when the cleaned parts were assembled and the tap fitted , there were no further leaks. Hope I've seen the back of this one now.
