No, that's not what I meant...with the old carpenters method, there will be no gap anywhere...even if it takes more than one attempt...

Place the snorkel in it's desired location, have a second pair of hands hold it exactly there, dead solid.

Lay the marker on the fender flat, with the point in contact with the snorkl base, "draw" the contour of the fender cross section on the front & rear of the snorkl base, then cut/grind/sand everything outside the line...

Repeat until a perfect match is achieved...
