    GM has a injector return spec for the LML’s which use basically the same system as these trucks. I will see if I can go back and find that. Sent from my iPhone using Tapatalk

    6.7 extremely long crank

    I did, a simple way to do it is bypass the return line going into the upper filter, pull the return lines off of one bank at a time and put small clear hoses on the return fittings on the injectors. Run those into a container where you can watch them. Command your low pressure fuel pump on and...

    The low pressure fuel system was replaced as well just to eliminate any variables there. Sent from my iPhone using Tapatalk

    Here is a video I took while the truck is running. When you rev it up at any RPM and let off the gas, the engine acts like it almost wants to die out, you can see the rail pressure drop down to around 4K psi Sent from my iPhone using Tapatalk

    I haven’t drove it all, I will drive it today and see what happens. I was trying to be cautious and not let something happen to this new system. I will give an update Sent from my iPhone using Tapatalk

    6.7 extremely long crank

    Just replaced the entire fuel system on a 2015 F550 because of a CP4 failure. Bled the system out and got the truck started but you can shut the truck off, crank it right back up and it will take 20-30 seconds of cranking for it to slowly start back up. Rail pressure starts around 3,500 psi and...

    Upper oil pan gasket

    Has anyone tried using a 2020+ upper oil pan gasket on the later model year engines? I know the 2011’s used an o-ring design. Just wondering if this new gasket would work on the oil pans that were designed to have gasket maker seal them. Sent from my iPhone using Tapatalk

    Exhaust popping noise

    It’s free of all restrictions, and has been for a long time. The guy who owns the truck doesn’t run it hard either. Sent from my iPhone using Tapatalk

    Exhaust popping noise

    Cracked exhaust valves were the cause of the popping noise. Sent from my iPhone using Tapatalk
