Defender / D2 fuel tank fittings

[100SRV]

Hi,
I have a Defender Puma TDCi fuel tank and wondered whether the combined fuel pump / level sender off a D2 would fit in it's place?

Root question is are the fittings on TDCi / Discovery 2 fuel tanks the same?

If not, perhaps those on TD5 Defender and Discovery 2 are the same...if they are how different is the fuel tank on Defender 110 PD5 to that of the Puma variant?

Hope you can help...
