Early model. Apparently this came from an OEM service manual. It’s a lot better than the diagrams in the Bentley or RealOEM.
I just joined this forum.
I have a 2 in-tank fuel system, one in left and one in right side.
Does the manual that you have show a diagram for this version?
Zinmo, I know of no E30 fuel tanks that has 2 in-tank pumps. You might be looking at a fuel pump on the passenger side and a fuel guage float sensor on the driver’s side. That’s pictured above in the late model pic.
