For those looking to increase the power output of their Porsche 911 Turbo (996), this plug and play (bolt-in) fuel pump replacement solution uses the most popular high performance fuel pumps on the market. The basic kit features a 6061-T6 CNC billet aluminum sleeve that slides over the corresponding 39mm aftermarket pump to mimic the larger 50mm diameter of the Porsche fuel pump. The machined rib snaps into the fuel pump hanger and properly locates the filter sock.  PUMP COMPATIBILITY For pumps not listed below, measure the outside diameter to ensure it is correct before ordering. If the pump is greater or less than 39mm (outer diameter), this kit will not work. -Walbro GSS341 255LPH Fuel Pump-Walbro GSS342 255LPH Fuel Pump-Walbro F90000262 Gas Fuel Pump-Walbro F90000267 E85 Fuel Pump-Walbro F90000273 Gas Fuel Pump-Walbro F90000274 E85 Fuel Pump-Walbro F90000285 E85 Fuel Pump-Walbro F90000295 E85 Fuel Pump-AEM 50-1000 Gas Fuel Pump-AEM 50-1200 E85 Fuel Pump-Aeromotive 340R 11141 Fuel Pump-Aeromotive 340R 11142 Fuel Pump-Deatschwerks 9-301-1000 Fuel Pump INCLUDED The blue male spade terminals will adapt to the internal OEM fuel pump wiring harness.
