I was using this DIY post
to educate myself and get the right parts for this swap out - I ran out of gas twice and have been getting shitty fuel economy. So I ordered the three parts as noted in the above-mentioned post (and a few other similar DIYs):
Fuel Filter. Part # 13 32 1 740 985 KAYSER
Fuel Tank Sending Unit Left Side. Part # 16 11 6 768 788
Fuel Tank Suction Device Right with Main Fuel Pump and Level Sensor. Part# : 16 14 6 766 942
while still at the office.
To my horror, I get to the car and pull out the rear seat and I see 2 wires on the right side of the tank, and NO wires on the left side of the tank. See the attached picture -- one set of wires is brown, the other is red. I lifted all the rubber covers and am positive that none of the wires are threaded under them to the other side.
All the part numbers, model descriptions (including wagon bodytype), and car year matched up between the forum post and Pelican Parts, so while sitting at the office i ordered them without thinking twice. Both level sensors were designated for wagons too...
I have a 2003 325iT(ouring) wagon...
Any thoughts, past experiences (and hopefully good news) are greatly appreciated.
