Hi folks!\n\nI lost my fuel filler cap of my Voyager, and I'm seeking replacement.\nThe owner's manual says to replace it by original part only because of\npossible harm to the emission system from non-chrysler caps.\n\nHow is it; are universal caps too tight or too loose; i.e. should they\nbreathe in or not to let air flow through them, or what's the problem or\npossible damage when using them?\n\nI wouldn't mind spending something like 100e for original because I can\nget universal at e 8.99,-\n\np.s. It's been lost for a while, and no problems w/ emissions (just\nchecked at inspection) so far.\n\nAnd another question... What's the box underside between driver's seat\nand the fuel tank? It's about 15x10 cm's plastic box with one aluminium\nand one rubber tube. Just found out that the rubber tube is a litttle\nbit loose, but I can't find where it affects. Is it the charcoal\nbreathing the tank?
