Fit-up and ordering options:

No other modifications are required to run the lager fuel filter with a Toyota power steering pump. Please note that the R150 brazed reservoir line will need to be massaged to fit.
 
For OEM Mercedes 300 power steering pump applications, please select the "Mercedes 300 Spacer" option. Please note that your fuel lines may need to be lengthened. This video explains how to make new lines: https://www.youtube.com/watch?v=dvpX6mqkvUU&t=2463s
 
For applications using a Doomsday Diesel power steering bracket, no spacer is required.
