Hi all I’ve just rebuilt my engine (92 fd RHD ) I really need a diagram for the lower intake manifold vac lines. I have one right at back near where the upper and lower intake join. I have no idea where it goes please help and thanks in advance

Jamie 👍👍

 

Rebuilt your engine but cant find the vacuum diagram?

Cheers for the pointless response 🤷‍♂️🤷‍♂️🤦‍♂️🤦‍♂️

 

I have the main diagram but it doesn’t show the lower intake. You dick head

 

All vacuum lines are on the diagram. It can be weird to read, but they are there.

You may want to post a picture of what you are trying to figure it out and we can help.

Dale thanks for the good response, yes I hear you it’s mostly clear on the diagram but weirdly I am struggling with a small looking acuator looking thing at the flywheel end of the lower inlet manifold at the top. If that makes any sense at all I’ll try and get pics

thanks Again

Hard to divine from your pics, but is the "actuator thing" behind where your hand is situated? Around about where the join of the upper and lower intake manifolds take place, there is the ACV and the pressure regulator lower down, that both take vacuum lines.

If it's actually on the exhaust side, the only things in the general vicinity, go to charge relief and charge control

 

Not easy to see in that picture but are you holding the vac line from the fuel pressure regulator on the end of the secondary fuel rail?

 

Hi all I believe it’s the pulsation dampener? But i can’t see where the vac hose goes and on all the blogs I’ve looked at it dosent even show a vac 🤦‍♂️🤦‍♂️

 

It's the fpr, not the fpd. It goes to the fpr solenoid in the rack.

 

The hose goes from the fuel pressure regulator to the end solenoid (solenoid nearest the firewall) and is placed on the nipple pointing straight upwards.
