I finally gave up on that aftermarket fuel filter housing for my Duramax

Had a customer's truck die on the highway last Tuesday, towed it in with a no-start. Traced it to the cheap aluminum housing I put on six months ago, it cracked right at the thermostat port and dumped all the fuel. I swapped it back to a stock unit yesterday and it fired right up. Anyone else had a similar failure with those shiny aftermarket parts?

My own shiny aftermarket housing lasted a whole three weeks before it split.

Wait, it cracked at the thermostat port? That's wild, I always figured the threads would strip first. Makes me wonder if the metal is just junk that can't handle the heat cycles. Seeing @owens.cameron only got three weeks is crazy too, I mean that's basically instant failure. I guess the shiny stuff is just for looks, which is a real bummer when it leaves you stranded. Maybe it's just me but I'm sticking with the boring stock parts from now on.
