CM2250/CM2350 Fuel Pump

100% agree with changing fuel pump/components every 400k (4 years).
It's cheaper than a new engine. My old pump had over 600k on it and luckily I had one that wasn't as prone to failures as the first revisions with ceramic plungers. They have updated many of the parts to handle the higher pressures since 2018. This year they are supposed to last around 600k before failure (stated from dealer), and will not damage engine if they fail due to the type of metal being used. Do I believe it? No, but it's good they're trying something different as even the steel plungers caused failures.
