Product Overview
It lets the technician manually refill and bleed the low-pressure fuel circuit after filter replacement, line service or an empty-tank event. A worn primer seal can admit air or leak fuel and make an otherwise healthy engine difficult to reprime.
The same Zexel/Bosch primer family appears across multiple diesel applications; thread/sealing geometry is the deciding factor.
Key Features & Performance
- Restores fuel prime manually: Lets the technician move fuel through the low-pressure side after filter or line service.
- Helps bleed trapped air: A sound primer simplifies purging air that can prevent a diesel engine from starting.
- Thread and seal fitment: The threaded body and sealing arrangement must match the filter head or feed-pump assembly.
- Product-specific note: The same Zexel/Bosch primer family appears across multiple diesel applications; thread/sealing geometry is the deciding factor.
Technical Specifications
- Operation: Manual fuel priming / bleeding
- Fuel system: Low-pressure feed side

Frequently Asked Questions
How do I confirm this is the correct part?
Match the original primer thread, seal and one of the listed reference numbers before installation.
Is this an OEM part?
Unless the listing is explicitly identified as genuine/OEM in the product data, treat it as a replacement component. Use the verified reference numbers, equipment application and physical configuration above to match your original part.
What should I check before installation?
Keep the primer and filter-head area clean to avoid introducing debris into the injection system.
Fitment note: Equipment manufacturers may use different components within the same model family based on engine, serial number or production date. Confirm the original part number and machine/engine details before ordering.
