    Can you pls refer what is normal fuel pressure . I always had around 80 driving and 70 idling . Truck is running fine loaded , uphill , flats , idling .
    Its got me thinking because friend of mine had some fuel system issues and after replacing fuel pressure valve he has about 105 and telling me that mine is low . If it is - how the engine affected ?

    You're within spec is what CAT would say but yeah you could do better. My MBN ran the same fuel pressure as what you get.
