I just swapped my Walbro 255 Fuel Pump to an AEM 340LPH because I wanted something better suited for E85. I  also did not like the “whine” noise on the Walbro. The AEM 340 does not have the whining noise and works great. I also replaced my fuel filter. Nissan says that it is a “lifetime” part and never needs to be replaced. I disagree with that especially seeing how dirty and filthy my fuel filter looked. It’s very simple to change and the filter costs less than $30 bucks. This is just a reference post and not really a how-to on the AEM pump

Fuel Pump Part Number: 50-1200 (Price – $116.00)
Fuel Filter Part Number: 16400-2Y505 (Price – $25.00)
Fuel Pump Sending Unit O-Ring: 17342-01A00 (Price – 16.00)

New OEM Filter vs Old Filter (Likely never been changed)

I cut the old filter so you can see how dirty and filthy it is.
