W164 fuel pumps
I’ve swapped out my fuel pumps 3 times in 4 years, have new filters and lines inside the tank, new flex hose in the engine bay, new injectors, new fuel pump modules and yet I keep losing pumps, what am I missing here? What can I check and try to figure out what’s happening, I shouldn’t have to have a set of pumps on hand as if it’s regular maintenance, I have recently installed long tube headers and a stage 2 eurocharged tube but this is happening since way before all of this was done so can’t be that.
