My question concerns the small jiggle type one way valve situated in the spigot just below the main filler cap. after removing the old valve ( not easy ) the jiggle ball was facing towards the filler cap direction and not the banjo bolt. From what I can gather that is the way they were fitted at the factory. I would appreciate any help with this dilemma as to me it dose not make sense and should face the banjo. I have a new valve ( $5 ) in Aus .and want to get it right.
