Message: [QUOTE="CamTom12, post: 1555565, member: 2662"] I bought this truck used and am not 100% sure of the mods on it, but it for sure has the ATS dual fueler kit and a large-ish non-vgt turbo. Ever since I've owned it (12 months and ~15k miles) it's had poor fuel economy. Like around 15mpg highway. I drive pretty conservatively, too. I noticed some fuel around the CP3 so I took it to a local diesel shop to see if he could find/repair the issue. He found the leak (fuel lines) and can fix it, but mentioned my poor fuel mileage was likely the CP4 failing. Is that likely? Is it more likely that I have crappy mileage because of the dual fuel pumps or because the CP4 is failing? Would I have any other indications of a failing CP4 in a dual pump setup? Thanks! [/QUOTE]
