Connection hose, oil tank to engine oil cooler pipe. Porsche 911 1972  ❭  91120730102

Connection hose, oil tank to engine oil cooler pipe.
This part is the flexible oil-hose connector that links the engine’s oil tank to the oil cooler feed line - forming a critical section of the oil circulation path. It ensures the oil circulates properly from the engine’s oil sump/ tank to the oil-cooler and back, helping maintain correct oil temperature, flow, and lubrication performance.

Fits:
Porsche 911 1972

Diagram ref no 31

Application: When rebuilding or servicing the oil system, replacing old or degraded oil hoses, or performing engine/ oil-cooler maintenance - this hose is critical to restore proper oil circulation.

Over time, original rubber hoses degrade: they may harden, crack, swell or lose flexibility. A failing oil-cooler hose can lead to:
• Oil leaks - risking oil loss and engine damage
• Reduced oil flow to cooler - leading to overheating, oil breakdown, and reduced lubrication efficiency
•  Increased pressure strain on other oil-system components or cooler fittings
•  Risk of catastrophic oil-system failure under load or during long drives.

Replacing with a correctly spec-ed hose  ensures you restore factory-level oil system integrity, optimal oil cooling, and long-term engine reliability - especially important for maintenance or restoration of a classic 911.
