Overhaul Kit for Bosch 0280150034 / 0280150036 Injectors in Mercedes-Benz V8 – Kit 189

Kit 189 is designed for Mercedes-Benz V8 applications fitted with Bosch 0280150034 or 0280150036 injectors, also identified by Mercedes-Benz part numbers A0000781623 or A0000783123. Check your injector numbers before ordering. It includes ethanol-resistant hoses and all the required replacement parts to refurbish eight injectors at home, with instruction sheets to guide you through the work.

Its ethanol-resistant fuel hose lets you upgrade older polyester-reinforced injector hoses, helping futureproof your classic car as ethanol content in petrol rises and fuel blends change.

Check the inlet before ordering: this kit includes eight injector hose ferrules and eight top fuel-rail clips. Compare your injector and rail connections with the product photos and confirm that your existing setup uses the same ferrule-and-clip arrangement.

⚠️ Why you should check your old fuel hoses

UK fuel can contain up to 10% ethanol. Older polyester-reinforced fuel hoses can degrade over time, becoming hard, brittle or cracked. Leaks can occur, risking an engine fire. At the same time as replacing the injector hoses, it is advised to check the fuel feed and return lines and any other hoses around the engine, and replace any that are aged, cracked, hard, or unsuitable for current fuel.
