Can I use Sea Foam in a HEUI diesel fuel system in a Ford F350? [SOLVED]

I have a 2000 Ford F350 Super Duty truck with the 7.3. Powerstroke diesel engine. This engine uses a HEUI fuel system which has a separate high pressure oil pump to regulate fuel to the injectors. ….hopefully you are familiar with this type of system. I have used your Sea Foam Motor Treatment in all my other vehicles and want to use it in this vehicle too, but want to make sure it’s safe for this type of HEUI system since it’s not a normal diesel engine. Many blogs online don’t recommend it in this type of 7.3 Powerstroke engine. Just wanted your comments… it safe and ok? Thanks for any help.

You bet Andrew. ┬áSea Foam Motor Treatment is safe to use in your HEUI system’s fuel. Use Sea Foam in the oil crankcase, too!
