What This Product Does

The hose forms part of the mechanical injection pump's oil circuit. Its role concerns lubrication of the pump, not the delivery or metering of petrol to the engine.

Functions

• Provides an oil connection for the mechanical injection pump.
• Routes lubricating oil through the associated pipework.
• Replaces a deteriorated or leaking pump oil hose.
  
  

Technical Details

• Product reference carried in the supplied record: 90111004103.
• Internal diagram part reference: 90111004102.
  
  

Symptoms of Fault

• Fresh oil around the hose or its connections.
• Cracking, hardening or deterioration of flexible sections.
• Visible rubbing damage along the hose.
• Seepage appearing after ageing pipework has been disturbed.
  
  

Why Replacement Matters

Renewing a damaged hose addresses leakage from this connection and supports the pump's intended oil supply. Inspect adjoining fittings and seals at the same time, since a leaking union can resemble hose failure. OE Match develops replacement components around Porsche applications, using original-reference and specification checks to guide selection.

FAQs

• Is this the injection pump itself?
  No. It is the associated oil hose, not a complete pump.
• Does it fit every vehicle in the supplied groups?
  No. Confirm the mechanical-injection equipment and the specific application before selecting it.
• What should be checked after installation?
  Inspect the connections and hose routing, then check for fresh oil seepage after the engine has warmed and cooled.
