Are they the same between the big turbo and small turbo cossies?

Its just that I've stuck a Group A 003 Bosch pump on ebay and been asked twice already whether it fits big turbo or small turbo escos. The capacity of the tanks are the same though which leads me to believe the fuel tanks are they same as well?

Can someone clarify for me please?

Thanks

 

Anyone???

Surely someone must know!

 

I'm sure they are exactly the same.
