Will be interesting to see what the real problem is. Too vague of a description right now.
My assumption was that the downstream emissions equipment was Fram parts. When I had issues with def injectors, Fram was on backorder and even though under warranty I tried getting them from Cummins and was told they were Fram only parts.
Regarding the fuel caps. Idk how they do in real dusty or muddy conditions with no cap, but I've only run these trucks in the snow and in a cold blizzard, fine snow, it would work its way into the fuel fillers and pack up in the filler neck with some getting into the tank when digging it out. On the trucks that lost the little plastic plug they came with.
