Side Breather cover gasket

I seem to have an oil leak from the side breather cover gasket, where the breather pipe from the rocker cover (not the cyclone) goes down and joins the cover. It has a few bolts securing it to crankcase but two of the are holding the injection pump mounting. Anyone know if it's possible to get this off without taking off injection pump?

The inj pump bracket is just a support bracket and so long as its all snugs up nicely you will be fine.

I think there is a baffle on that cover that prevents it sliding straight up?
But yes, remove the bracket if necessary, no harm will be done just dont crank the engine whilst it's off to be 100% ok.
