S54 to E46 Touring fuel system

[snaponbob]

It has occurred to me that the E46 M3 has a different fuel pump than the other 46s. Is this something I need to address? It would be logical that the S54 would have greater demand.

Higher pressure, I believe. Most of us that did E36 S54 swaps put the E46 S54 pump in the E36 carrier, works fine.

NOT "huffed". Will be low back pressure exhaust (AA catless headers, Bimmerworld collector, and custom 3.5" exhaust) and two pulley underdrive system. I did a Walbro in my 07 Saturn Sky Redline when I went E85, and it dropped into the stock pump system. What is the E46 setup for the Walbro 190?

Not sure, I have an E36 S54 with a 255lph walbro. I think it’s overkill
