R112-SD220 Exhaust Gasket

I have a R112 I got running after sitting 20 years. Has a SD220 Engine. Runs good once i installed a new fuel pump. This truck has an exhaust leak from the square gasket at the bottom of the manifold. I do not have a service manual but do I need to pull the entire exhaust manifold off to replace it?

Thanks,
Mike

If you are talking about the gasket between the manifolds, then yes they have to come off to separate and replace the gasket, which will come in the manifold gasket kit.

Thanks. That is what it looked like. Any good sources for the gasket set?

I was a little disappointed that when I got the new Carter fuel pump that the flange that bolts to the motor was thinner than original so the original bolts were too long. Was not too impressed with the quality of it. Maybe I should have looked for a NOS one. Oh well I guess it works.
