I remember when they came out with the low sulfur diesel fuel. We had about a half dozen roosa- master injection pumps where I worked and all of them had to be rebuilt because of the fuel change. Now with the new engines most of the injectors are oil activated instead of using injection pumps. Now they're all electric over oil pressure. Hi-pressure fuel pumps are a thing of the past now they use Hi-pressure oil pumps to push the injector plungers down. These Hi-Pressure oil pumps are separated from the engine oil pumps but both use the engine oil. They are now using Hi-Pressure fuel pumps to activate the injectors. Pressures are as high as 12,000 lbs. The pressure has to be high to pop the injectors at the correct time and the faster the engine runs there is less time between pops.
