Hello Everyone

My FJ40 is coming along and as soon as the carb gets here from USA it will be running( I hope )

Since I bought my FJ40 with so many missing parts I'm force to ask the experts
Below is a photo of a manifold inside the red box there is a connection where does that go? and is there a gasket between the in/out manifold?

Thanks once again

brake booster

yes

The union on the intake goes to the brake booster (the thing you have circled in the square )

There is a gasket between the two

The port on your red intake box is for a brake power booster.

There is a gasket used to seal the mating surface between the Intake/Exhauast. The stock gasket is fairly thin. If when you bolt the I/E together and find the bolt ears don't line up you may want to stack two thin gaskets. Many on here swear by brush on "copper coat" for added sealing of the exhaust ports. Some just use a high quality Fel-Pro manifold gaskets and no sealant. Fel-Pro says no sealant is needed or recommended with their gaskets.

Another option exists to better re-align the bolt hole ears of both manifolds. I ended up using a single RemFlex heat riser gasket. It's much much thicker than the regular heat riser gasket I bought. My manifolds were warped enough the the bolt hole ears didn't line up very good. The thicker gasket helped with that.

Make sure you use the proper 3 bolts to sandwhich both I & E together mine were m10 x 1.25 pitch. Bolt together and take care not to over tight the 2 bolts in the aluminium intake. Once together, if both mating surfaces aren't flat it might be a good time to have them surfaced as a unit. I wouldn't recommend surfacing them when seperated.

Is that a 1974ish intake?
