Gas smell after filling up from beyond empty
My 2005 Z has almost 159k miles on it. I regularly fill it up from "empty" with about 15gallons of fuel. A few weeks ago I was double-checking the actual tank size as was surprised to find that it holds 20gallons (not even my Passat or V70R have a tank that big...compared to everything else in my "fleet", only our '05 Ram Cummins has a larger tank at 34gallons).
So, I decided to extend my time between fill-ups and run way past empty. This got me over 400miles from the tank, and then when I went to fill up I encountered new issues...
1) When I filled up from way past empty, I could only get ~14gallons to go in the tank, and then it struggled to add any more. I gave up and left it ~3/4 full.
2) I used to have a gas smell from right after I filled up until I drove through a few gallons of gas. The gas smell is now WAY more prominent.
I do have the CEL lit on the dash (it's been that way since I bought it, essentially) - the code is 0455 EVAP Leak. Reading on different issues, it looks like my Z probably could have had the EVAP hose TSB/recall done a few years ago, but the previous owner and I missed the window for the extension (15yrs and 150k miles).
So, I'm planning to replace the fuel tank gasket (I've read here that those tend to age and allow a fuel smell with a full tank), and then it looks like I'll have to replace EVAP hoses, as well. But is there anything else I should expect to find/replace?
Now is the time where I should finally pick up a diagnostics tool, too. I have been eyeing the NissanDataScan SW for the PC. I use similar tools for my VW, Volvo and Ford via a laptop interface, and this seems like a decent solution (feedback on this is appreciated).
I'd appreciate any input from BTDT experience resolving a similar issue to the symptoms I describe. Thanks!
