I logged on to Chilton through my library (you likely can do the same), They did not have info for the '89 but they had some info for the '92 190E. Here is what they say for fuel pressure test:

"Disconnect the fuel line at the fuel distributor and connect a pressure gauge 103589002100 or equivalent, to the hose.

Connect an adapter 102589066300 or equivalent, to the plug fitting at the fuel distributor.

Jump the fuel pump relay at the manifold and check the pressure. If not within specifications, check the fuel filter and pump pressure at the pump.

Disconnect the pressure line at the fuel pump.

Connect a pressure gauge and adapter to the fuel pump outlet at the pump. The pressure should be 29–58 psi (2–4 bar).

Reconnect all fuel hoses and check for leaks."
