Now the tricky part as it won't come straight out. Not much is 'easy' on commodores. The assembly needs to be wiggled and turned around very gently to clear the internal fuel tank baffles. Hard to describe in words, but its important to take note of how it was removed [angle etc] so you can repeat the proceedure when installing the new one.
With the pump assembly out, follow any instructions that came with the new one on how to remove the old pump off the fuel line, filter etc. Be aware that the whole assembly is a little fragile and you may bend the fuel sender lever if not carefull.
They say to use new bolts on the flange, I used the old ones and seems fine as its been running now for 6 months.
Good luck.
