Not sure exactly what you've tried to write there, but I assume you are asking if you can fit a mk3 Vr6 intank pump to your mk2 .. not into the mk2 tank, but if you have the complete mk3 tank you can fit that and remove the mk2 under-car pump. It's a tidy mod

get the mk3 undercar fuel filter housing too (bolts straight to two of the bolts used for the mk2 undercar pump) and connect it all up. You want the connector for the mk3 pump too so you can splice it into your wiring.
