The e28 in line pump is smaller in diameter then the original pump and the bracket will not work. You can order a bracket for an e12 inline pump which fits tight in to the mounting tabs under the car. The bracket is identical with 2 exceptions-
1.the e28 pump fits
2. The bracket also has a fitting for a fuel filter.
You will need to make a jumper from your plug to the newer e28 pump.
Thanks Mike!
