The past few times I’ve tried to fill up the gas tank the pump keeps shutting off after just a few seconds, no matter how slow you try to pump in the fuel. It took me a while to finally get the tank full. This is new behavior for this car. As part of the diagnosis, I decided to check out the roll over valve to make sure that it was allowing the vapor from the tank to pass through to the charcoal canister during fueling.
Finally got fed up with the host of evap codes on my 1998 V70 AWD and went ahead and replaced the canister hoses, rollover valve hoses, purge valve (and surrounding hoses), and the three inches of rubber line connecting the small vent filler tube to the hard plastic line coming from top of fuel tank. I didn’t order any special hoses, rather went to Autozone and bought a variety of molded J and U hoses (they were kind enough to let me go the back and pick out what I needed).
