The accelerator cable is a common item which fails. First it starts fraying and stretching and eventually it'll just break, leaving you stranded.
This particular cable is 3550mm long and is designed to fit right hand drive manual baywindow Kombis from 1976 to 1979 with a type 4 (1700-2L) engine and standard twin carburettors. This will not fit automatic Kombis or ones with an upright engine.
This is a quality Gemo brand item
