So ?
I don't see Heshan said which pump he used before, so i didn't want to make any assumptions. If he used stock 4AGE on 4AGZE, especially 20+ years old, i guess he could have some problems.

What is a fact is that 255 LPH is more than enough for much bigger engines, even Turbo ones. But, it can't hurt smaller engines, and since he already got it, he should use it.

I'm using the same 4AGE fuel pump on my AE92 running the same engine and I don't have any problems at all. The 4AGE pump is ok unless you want more KW or you are planning on putting in bigger injectors then the new fuel pump would be advisible.
My mechanic told me that when I am going to run the ZE with a turbo, then I would need to change my fuel to a bigger pump.

Heshan, if you want to see greater gains on higher revs, then camshafts, port&polish and bigger injectors would be your best option seeing that you've got a bigger fuel pump. The SC14 would also be a better charger for that.
