Fuel return line, Fuel Hose
This is the hose that connects the fuel return on your engine to the fuel system, its a small piece but when cracked it will brake the vacume in your fuellines an will cause problems when idling your engine or even shut off
Unfortunately, After 40 years of being exposed to fuel, heat, cold and dirt, allot of the original return hoses are dried out and in need to be replaced to avoid fuel leak and vacume leak.
Thats why we offer this replacement hose especially for the OM314 & OM352 equiped Dudo Vehicles.
