Hi. I will replace my diesel pump with a new one. i have an afn engine with the old pump you have to turn to adjust. my question is if the pump from ALH can fit if you replace the plug

You can re-pin either the car harness side of the pump side (not recommended since most wires to the QA are the same color--black) with the correct connector shell.
But in order to get the ALH pump to fit, you'd also have to machine down the ALH pump's pulley and machine/bore a larger opening into the pump bracket to get the ALH pump to fit.
Not really worth it, . I've even go so far as putting 11 mm ALH pump parts into AHU/AFN pumps before for the early engines, so that way I get the 11 mm performance but keep the stock appearance and adjustment style of the factory pump. Saves a lot of time and headaches on machining parts and swapping wiring pins, anyway. Just need the pump head, plunger (and the washer on the back of the plunger) and the cam plate to swap into the old pump to do the conversion.
