I went through this not so long ago. My fuel smell was caused by old fuel lines in the engine compartment leaking immediately upon start-up. (not a good thing). It's an unusual size, make sure they give you the right one, I purch mine at a Napa parts, in a meter length, about $25, still less than from bmw. (about $15 a section, 1 or 2 short, 2 long, and 15 minutes) My starting problem was caused by a bad air flow meter. (wouldn't idle until warm) It ran horribly at first start, idled very rough, and then smoothed out. Replaced that, fixed the start problem. Hot start problems are usually O2 sensor, as it supposedly controls eng mngmnt at operating temps. But now mine idles rough for the first 15 secs, then good but no fuel smell-it's the injectors turn to be replaced. Good luck
