2010 f150 4WD vacuum check valve

Can't say for sure but, looks like the same design on the outside. Is that a Doorman? I know others here have not had much luck with using non-OEM parts (especially Doorman) on the 4WD system. The Ford OEM check valve is pretty cheap, around $10. So, I'd go that route.

Yes it is a dorman. I will be driving home next week and don’t have the time or a address to order now. I’m replacing my IWE solenoid, nobody had the right valve and the videos I watch said it’s good to replace both. I’m replacing it tomorrow and probably want need the Valve but will have one shipped to my house still, I just wanted to change both at the same time while I was at it
