You are correct that there are two different fuel pumps available for your car. One allows for "vapor recovery" while refueling...marked "WGL". And the other one does not, it's marked "WGG". Original equipment was a Bosch marked "WGL". Okay. I would take the old pump to the parts store and do a side-by-side comparison. There has to be a visible difference between the two and it has to be right. You can thank the EPA for that headache. Good Luck
