Overhaul Service Kit For Jaguar Pre HE XJ12 XJS V12 With Bosch 0280150035 Lucas 73143B - Kit 105

Injector Overhaul Kit for Bosch and Lucas Injectors in Jaguar Pre-HE V12 – Kit 105

Kit 105 is designed for pre-HE Jaguar XJ12 and XJS V12 models fitted with Bosch 0280150035 or Lucas 73143B injectors. Check the injector numbers before ordering to confirm fitment.

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: the standard fitment has a double-arrow inlet port on the injector and a single-arrow port at the fuel rail. Ferrules secure the hose to the injector, and hose clips secure it to the fuel rail.

What’s included

• 12 × ethanol-resistant fuel hose lengths, cut to suit the application
• 12 × hose ferrules for the standard Bosch 0280150035 / Lucas 73143B configuration
• 12 × hose clips for the fuel-rail connections
• 12 × injector filter baskets
• 12 × inlet manifold seals
• 12 × pintle caps
• Instruction sheets to guide you through the work

For Bosch 0280150014 or 0280150023 injectors, the ferrules are exchanged for additional hose clips. Add a note at checkout if you need this alternate configuration.

⚠️ 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.
