It's surely possible. The checks looked and felt like a bog standard 75-ish durometer Buna-N which would not be the best choice for use with bio. The inlet check was in perfect shape though, so I was left with the assumption there was a chemical defect in the one that caused it to fail.

A company like Cummins could easily have pistons supplied by one place, outlet fittings supplied by another, castings supplied by yet another, then carry out assembly at a separate location. If that is the case, and each manufacturer is on their own for sourcing materials (not an uncommon practice in China), it'd be a near certainty that the two check valves aren't coming from the same molding plant.

Change your fuel filter, check for plugged fuel heater, before you waste money on a new lift pump.
