I was under my RRC adjusting the hand brake and noticed a hose that is not connected and I can't seem to find where it should go. It comes out of the cross member above the rear diff. (outlined in red) It has a black plastic cylinder (smaller then a Coke can) connected then an open pipe. Any ideas?

Does your 1993 RRC have air suspension, or did it originally? And is the black plastic cylinder that is smaller than a coke can a bit rounded? If so it could be one of the exhausts from the air suspension components. They have a muffler on the end which is a small cylinder.

I took a quick peek under my '95 LWB and have the same hose. The larger diameter rubber hose goes through the x-member and I believe to the fuel tank. The plastic cylinder is inside the LH chassis rail, where it transitions to a plastic hose (slightly larger OD than EAS airline) that routes to the front of the vehicle. I didn't have time to trace it past the EAS Compressor, but I think this is the fuel tank vent that goes to the EVAP canister under the bonnet.

My EAS exhausts are located behind the LH rear wheel splash guard.

That is how the round cylinder looks. It originally had air suspension, but was removed before I bought it. It started to rain before I could take a photo of it.

I have looked through Rave and I can't see any mention of a connection to the fuel tank at that location. The EVAP should connect near the filler. However When the fuel tank is full I get lots of fuel vapour odours. I will follow the EVAP hose from the canister back and make sure it is connected.

On further inspection I found another hose which ends next to the fuel filter and goes up near the fuel filler, It started to rain before I could fully trace its origin. I think this might be an old EAS pipe.
