Walbro Fuel Pump for 97 NA SW20

Hey guys,
 
I'm getting a new fuel pump in preparation for a 2GR swap. Will be getting the Walbro 255 High Pressure. Part number for that is GSS341.
 
Think I'm not sure about is the fitting kit. I called one place and was told the MR2 kit only fits up to '95 as the fuel pumps changed size after that. Does anyone know which part number fitting kit I need to for my 97 NA?
 
Cheers,
Adrian
