Hi everyone,

I'm guessing this is quite a basic question, but I'm not sure if I'm using the correct name. I want/need to replace these rubbers as they are very dried out and are starting to crack. I have no idea what they are called or what the part number is. They are used on a single weber 32/36 carburetor and a 1.7 Type 4 engine.

I guess I also have to replace the gaskets on this side, as i think I'll need to remove the pipes in order to get the rubbers out:

Is this the gasket I need for my engine:

Or something like this:

Is there a place where I can find torque specs, or info on how tight I need to retorque these bolts?

The first link is a better choice for gaskets fr a progressive manifold, the flanges are never fully flat and the metal gaskets don't seal.
The rubber boots are from a type 1 dual port 1600 manifold, search for parts for a 1971 bus, or 71-74 beetle.

Buy quality boots, there is a lot of junk out there. Note that the bottoms of the boots typically looks far worse than the tops.

Ok thanks for the responses, I will go for the heavy duty inlet gaskets.

For the rubber boots, I'll need something like this, if I understand you correctly:

They are for a 1600cc type 1 engine, but as I'll understand from @busdaddy they'll fit on my intake.
