Halp! Can i rebuild this LG4 vacuum harness myself? Its impossible to find.

This harness is so hard to find, and its broken in several places. The elbow connectors don't come off, so they cannot be replaced, and the thing with the double pipes going into it, well, i don't even know what that's called.

I've looked over amazon and ebay, but i am not sure what parts i can use to rebuild this.

Any ideas?

if they're all plastic then yes. Get the proper size line and use a little bit of heat on the line to make it pliable so you can shape it. plug it into the big rubber fittings and you're done.

The thing with the 2 pipes doesn't really have a name.

Doesn't have to be replaced by a thing with both pipes in it; 2 individual ones work fine. Only reason the factory did it the way they did was to make it faster to assemble.

You can get every piece needed to replicate that functionally, even if not looking exactly the same, at about any parts store.
