Water pump type

[Wally2]

I ordered a load of bits from mini Spares for when I change the cylinder head, one of which was a new water pump, the GWP 132 for 848cc engines. However, the one that came was a GWP 134 (in a bag marked GWP 132!). The difference being that the impellor is deeper and the write up on the description on the MS web site says that it will interfere with the block liner wall but it can be used if clearance is created. Mini Spares will change the pump for the correct one but has anyone tried fitting the higher capacity GWP 134 in an 848 engine?
