California has a new emissions test as of December 1, 2007. It is a low pressure leak test of the fuel EVAP system (LPFET). I was lucky enough to fail this test today (passed all the other tests, though). In talking with the technician, it seems they pressurize the system with nitrogen through the fill pipe the measure the leakage flow rate. I think he told me the limit leakage rate was 45 and my truck measured 90 (I don't know the units, though). He recommended I check the hoses for leaks.
I've done a quick check, and although things are a little dirty/dusty, none of the hoses seems brittle or damaged. The technician also implied that I should just look at the hose assoicated with the evap system, but shouldn't I also be concerned with vapor phase leaks at the gas tank, fill pipe, etc.? Short of replacing all the hoses, does anybody have any experience or recommendation with getting this repaired? Thanks.
