Hi I was just wondering I have a 1.0l polo 6n and going to do an engine swap soon to a 1.6gti but I was thinking will I need a new fuel pump if so what part of it and could someone send me a like to the right bit? Please thank you

Is your 1.0 a Multi-point or single point injection ?? if it has 4 individual injectors you don't need to replace the pump, if it doesn't you'll need the 3 bar pump part No. 1H0919651P fuel pump with housing 3BAR

Thanks mate how can I find out?

If there are 4 injectors on the inlet manifold you have a multi point system and the fuel pump is the same unit for a 1.6GTi If there are no injectors on the manifold you have the SPi and then you will need the pump I listed above
