That actually the right side of the engine, on most conveyances left and right are always "as seen" from the driver's seat.
The hose is the evaporative emissions system (EVAP) vacuum line to the EVAP canister purge valve. It is not uncommon for this line to soften with age, and because it transports fuel vapour to the intake manifold, and collapse when manifold vacuum is high.
It needs to be replaced, make sure you get thick-walled vacuum hose, you can also use fuel injector system rated fuel hose--it's 3/8" ID.
