Default Injector question?

Is it required to have an adjustable fuel pressure regulator with 22lb Bosch 3s on a stock 91 L98? Or can I keep the stock fuel pressure regulator?

The stock regulator should be ok.

Unless you run out of injector and have the ECM tuned for it, I would just stick to the stock regulator. I heard the theories of better atomization with higher pressure but I am not aware of tests that prove the gains are significant under street conditions. Sure, if you were racing for a living, I'd push anything that gets me a thousandths of a second.

Nothing like that just want it to run like it did from the factory. I'm replacing the Bosch 3 yellow/orange injectors with the grey Bosch 3 22lb. I'm receiving them tomorrow. Just wanted to know if I could keep the stock regulator.

You could but I'd change it just to be sure. The rubber diaphragm is old.
