With hindsight, I'd have saved a lot of hassle if I'd put it a little higher up the wing, to face more directly downward. Where I put it left little room between the grp panel and the car itself.i had to fit in an elbow in the filler line to direct it down to the Z3's own filler, which was a struggle.
