"n some cases, this model has a plastic drain plug. We don't currently have a solution for the plastic plugs. If this is not your case, please choose a valve listed below. In addition, this Ford model uses two differently sized drain plugs. One is M14-1.5, while the other is 12mm-1.75, we suggest getting your drain bolt measured."

Any clue which one I need for a 2024 F350 SRW with the HO?

Fumoto is tripping, they have included, and not corrected that confusing wording for way to long. The only 6.7l pan that had a plastic drain plug was way back, something like 2011 or 12. Also, the 6.7l in the pickups only use 1 size drain plug, M14-1.5. The other size they mention is used on the gas engine pans.
I'm sure it has been brought to their attention many times but they never make the correction to their site.

 

I love my Fumoto valve, and I've also used them on most vehicles I've had in the past. Wouldn't do without one. Having said that, I will mention that the design of the lower oil pan on this 6.7 engine and the location of the drain hole prevents all the oil from draining. For that reason, what I do now is I park my truck in a spot in my driveway where the nose of the truck is uphill, then I drain the oil. I'll put 12 quarts back in when I'm done, move the truck to level ground, and check the dipstick to dial it in.

It's still much easier than making a mess with the threaded drain plug.

 

It’s funny. I was out in SD last week. Stopped in Rapid City at the dealership to get the oil changed. The guy who changed my oil was talking to me and complaining bitterly about the plastic plugs on the newer trucks.

 

He wouldn't have been talking about Super Duty's though because they still (as of MY24) do not use a plastic oil drain plug.

 

He specified the 6.7L Power Stroke. Since mine is a 2019, I haven’t seen the newer trucks.

 

He was mistaken then.

 

I used this on my 24 F350 Limited. https://a.co/d/5GLIicl

 

Thank you! Ordered.
