yeah... i though so.
SO yup. the pump you have it the same part number as the one you would get for a 2G kit anyways.
You will be just left over with the wiring adapter and a small length of hose.
And usually when installing a walbro into a 2G tank i think you might have to fiddle with the bottom "L" bracket that holds the stock pump up against the "cap and oring". If i remember correctly on my 4G colt i had to drill a new hole in the bracket so it would allow the walbro to sit properly in the cradle. I also had to use a 2X4 and hammer the bottom of my tank down a bit so the pump wouldn't be shoved against the bottom of the tank but the 4G colts use a metal tank... and i believe a 2G tank is plastic... so that might not work so well.. HAHAH
yeah pretty much lift your rear seat up, pull the access cover, disconnect the fuel lines and wiring connector and then undo all the little 8mm nuts.... lift the pump assembly out and you will see how easy and straitforward it is.
Good luck!
