ArdWrknTrk Posted May 11, 2021 Share Posted May 11, 2021 I replaced the lines after cleaning up all the little bits. Does anyone know where the line where the T connection port goes to? I can't make heads or tails of the vacuum diagram. It was not connected on my truck. The metal coupler that connects to the carburetor is staying in so far. I think it was not in deep enough before to stay because the rubber hose was slid on too far. Can you show a good pic of the diagram? Sorry if I'm not following the thread on my phone...

ArdWrknTrk Posted May 11, 2021 Share Posted May 11, 2021 Can you show a good pic of the diagram? Sorry if I'm not following the thread on my phone... It can only go to the charcoal canister or the purge solenoid.... Link to comment Share on other sites More sharing options...

It's more clear than a vacuum diagram under the hood. It looks like it is going to 9B963.

I was not sure how it would work attaching a picture. I guess it won't attach like normal. Link to comment Share on other sites More sharing options...

A check valve to the upper sprue of the PCV valve (which is above the weight) Link to comment Share on other sites More sharing options...

ArdWrknTrk Posted May 11, 2021 Share Posted May 11, 2021 And here is the diagram. Well the line atop the PCV should be connected to the purge valve (as shown in the manual) Then the dotted line to the EVAP canister(s) (Which I assume aren't there) The tank vents are probably the metal line coming from underneath. Then the other dotted line, to the open Tee on your bowl vent line. Link to comment Share on other sites More sharing options...
