Agree with v8volvo about the IP, when always fed clean high quality fuel, can last indefinitely.
One thing that can shorten its life is running with a clogged fuel filter or other fuel supply obstruction. This can cause the IP's internal fuel feed pump to disintegrate and send metal shavings throughout the rest of the IP.
Another problem (usually not catastrophic) is seal leakage, often caused by fuel reformulations or other major changes in fuel type. Many here have replaced the various o-ring seals on these IPs. On second thought, seal leakage resulting in fuel leaking out of the IP
CAN turn catastrophic, when the fuel leaks onto the rubber coolant hoses below the IP. The fuel-soaked (now) deteriorated coolant hoses burst and the engine overheats quickly. There goes that aluminum head you mention above.
