I doubt the mount itself is tweaked my bet is that the pump is out of alignment. Do a search of Belt tracking and you will find the topic
so you got the car and it didn't have a belt tracking issue and you are using the same injection pump?so if you are using the same parts and took the bracket off and pressed in another mount, you could easily bend it with a press. i know i have used a cut one in the garage as a spacing plate and it bends i wouldn't want any part of trying to bend something like that straight. i use the im shaft pulley with no lips because i had read on here that its better at not chewing up and came that way later?if nobody screwed with shimming the tensioner pulley(old owners do crazy things), don't know what else it could be in your case?for whatever reason most of the time i come across a pump that tracks to the outside of engine.if i thought i bent the bracket i would just get another myself before attempting to adjust the injection pump bracket? but sometimes you got to do what you got to do?its an annoying process of changing position of injection pump bracket that attaches to front of block, then putting pump back on and turning motor over a good number of time to see where it settles. i have had it take a handfull of tries before.to make it a bit easier put everything at tdc with pump lock pin and clamp belt to sprocket and sprocket to bracket. so you can then line pump keyway into the sprocket taper, hand tighten pump mount bolts and torque the sprocket bolt to pull everything back into place.definately get a second opinion on this, but i believe you want to move the bracket the opposite of what your instinct would say. so in your case i think you want to drop the right side of the bracket down to get the belt away from the engine.
First off, relax. 99% of the time, if you remove the pump bracket and reinstall it, you need to adjust the tracking or it will be way off. Yes, a PITA, but both to be expected and in the greater scheme of things very small potatoes. To get the belt to track closer to the block, the injection pump bracket needs to be adjusted so the sprocket end moves DOWN and the end with the metal lines moves UP. If you need it to track farther from the block, then you need to move the sprocket UP and the metal lines DOWN. Remove the belt and bracket. Loosen the two bolts that mount the two bracket parts together and the two bolts that mount the bracket piece behind the pump to the block. Push it UP if you need the line side of the pump to go UP, or DOWN if the line side needs to go DOWN. Install the pump and belt and run it through a few revolutions by hand and see where it lands the tracking. If you need more adjustment, then you will need to loosen the bolts fastening the flat piece across the block and push that the other direction. If it's a mk1, you'll need to jack/lift the engine in that case.
The bolt holes are over-sized in order to give adjustment. If you need it to track away from the block, then loosen the four bolts (two that bolt the bracket part behind the pump to the block and the two that bolt that part to the other bracket part) and I'd start by pushing it down as far as it will go.
