This fuel clamp is used with the 5mm low pressure cloth fuel hose in the fuel tank breather system.  This is the small hose that travels to and from the fuel expansion tanks in 2WD and in the rollover valves in the Syncro.

In 2WD Vanagons, there are twelve of these clamps used.

In Syncro Vanagons, there are five of these clamps used.

NOTE:  These clamps are used on low pressure fuel vapor hose and the new hose hits very tightly on the varous fittings.  Some mechanics do not bother replacing these clamps though we recommend them.
