Yep. Ended up calling Walbro today. The F900000267 will work. Just need to dial fuel pressure way back. Ideal is around 80. Pump gas will require around 60.

 

Sorry I know this is off topic, but do yall guys know what this plug is? It's right above the emergency brake release and hood release.

 

I can't remember lol, we all have one tho. I use to know...honest! I can tell you what its not, it's not the brake controller. That's grey also and has 6 wires. That's just behind the OBD port.

Crap, what is it ? I wanna say test port ? -I'll attempt a search.......... Wow, no luck. I know there's a name for it lol.

What's green and red on the wiring diag ? Could look there.

 

It also looks like a plastic panel covers it up normally? It looks like a tab to connect something down below it but I have nothing there

 

I asked at a few fairly knowledgeable Ford sites this morning. Some say it's a clutch input switch connector, others say it may be an auxiliary idle connector. No fully confident answers. Clutch Input sounds logical IMO, but still can't say for sure. I may have to go to diagrams yet lol.

 

Perhaps you should begin a new thread, these engine builders won't know anything lol. No offense

 

I have an automatic, so that wouldn't make sense to me

 

All these trucks have the same harness

 

[MENTION=99584]ibd2328[/MENTION] probably knows

 

Oh
