Ive been affected, and bearing in mind the danger associated with petrol, IMHO ----brace brace (brace------
Buy the most expensive ie as already advised, a genuine mercury perhaps.
Simply ask- "IS this genuine part?"
Nearly always Ebay does list "country of origin"

I agree sometimes, its difficult to buy GOOD STUPH, but on this case its simple.

The tubing is similarly affected, and even genuine expensive RATED and stamped tubing can be affected.
