Stick your finger into the hole you took the mechanical fuel pump out of.
You will feel a push rod that goes up when you stick your finger under it.
To install the fuel pump, you must keep the rod up while you put the pump lever under it while installing the pump. Once this is done the pump goes in without a problem and can now be bolted in place.
Good Luck and let us know how it works out for you.
