Hi James,
i have that exact model pump 😬and use it on the seven (dry sumped)and my smart (they have no sump plug) great bit of kit
Ditto to Dave above works a treat *thumbup*ten minute job and No mess
got to make sure it's at the very bottom of sump though,as there are a few ledges, that can seem like you are at the bottom,then just pump up twenty times, go make a cuppa and hey presto all done
Cheers
