Hi all,

Suspecting a possible plugged catalytic converter on an 03 ranger and trying to verify with a backpressure check per the ol haynes manual.

Problem is I'm kind of an idiot and cant figure out exactly which vacuum line Im looking for. :icon_confused: I've looked at the line diagram in the front of the engine (see pic below) and I've not figured out where I should plug my vacuum gage in.

Based on the actual pictures below, could anyone please give me a pointer on which exact line needs to come off and get the gage on it?
