If you sit on the back seat and facing infront there are 2 fuel tanks, one on your right which contains the fuel pump and the left tank which only contains the float. If you'd seen the puddle of petrol on the left tank float chances are you got the same ,roblem like i had. Actually the yellowish colour surface of the float had hairline cracks which are not vivible to the human eye. Well if the hoses near there are ok then u must change the float. Only costs about 100 or 200 plus. And while you're change it please check you fuel gauge at your dashboard. Install the float well so that the fuel gauge works normal again. Sometimes it will read lower than max when we'd just fill in full. Fyi i've just did mine 2 days ago with 328.</p></blockquote><p></p>
