12A water pump upgrade

Post by TOOL » Wed Aug 27, 2014 10:00 pm

This thread is about installing an FC water pump onto a 12A plate.

The FC water pump housing is aluminium, so it's a weight saving for a start. The FC pump is also less prone to cavitation at higher rpm so is a better unit.

You need to remove some material from the 12A front cover to make it fit.
Not much though. See pic.


You also need to take a similar amount off the back of the water pump housing.

Easy upgrade.

EDIT: the same applies if you want to fit a 12A front cover onto an FC engine to install in an FB using a front mount.
