Connecting a fuel pressure gauge 280SE

[Feather535]

I'm getting ready to set up a gauge to do a series of fuel pressure tests on the 280SE I rescued, but I'm still learning the names and locations of fuel system parts that seem to be specific to these cars. The online copy of the factory manual (https://cdn.w116.org/tech/K-Jet_Diagnosis_Adjustment.pdf) says "install the gauge into the control pressure circuit."  Is that the solid line that comes off the top of the fuel distributor in 6 cylinder cars?  And connects to the device that is also known as the WUR?

Correct.

I probably should have said "the middle of the fuel distributor"...I guess the lines to the injectors also come off the top.

Check out Mercedessource on youtube I recall a recent video where uncle Kent tackles this very topic on a 280 engine.
