Yes....and no. Injectors are not sealed internally like gasoline injectors are. and some leakage is designed in to lubricate the pintle. The amount NOT injected is so small as to be of no account.
The only way to inject more fuel is to move the rack further toward full load position or increase the size of the i/p delivery plunger barrels.
