Hello, my name is Tucker I'm trying to fix my grandpa's old Ford and Im tired of dealing with the smog and efi misfires so I'm just going to put a carburetor on it. It's a 1990 Ford XLT lariat with the 300 inline 6 and I can not seem to find a YouTube video anywhere for it so I came here. Any comments or tips helps just going with the most cost effective way possible (I'm a broke 17 year old, yes broke because of this truck). Any ol timers with trucks up their sleeves would be awesome, thank you.

 

Welcome to the forum. Maybe this will help.

 

Yes the information about the wire harness was helpful but I'm also going to put a manual fuel pump in it so it wasn't as helpful in that sense but still good for future reference, it sounded like he just took out all of the vacuum lines as well is that true? I was trying to find a conversion on a 300 inline 6 just for the closet comparison which was the part that was so difficult. Thank you for the video it was still really interesting.

 

My advice is to fix the issues with your 4.9. I can't see any advantage to attempt converting an EFI engine to a carburator. I liken it comparing an automoble to a horse and buggy.

 

If misfires are an issue, and they darn well could be if that’s a 36-year old engine in that truck, then you’re just spending money to swap to a carb and still having misfires. Misfires come from lack of fuel, spark or compression.

Let’s actually fix what’s wrong before we start clogging up the plumbing for no reason at all. This involves actual diagnostics.

I won’t claim that early 90s Ford EFI is the latest and greatest stuff-I don’t really mess with 9th Gen trucks now-but, don’t condemn it without reason just yet.

 

It's a fuel supply issue with injectors but I also like the clean engine bay after the carb swap and at this point it's more reliable but it's also easier to work on a carbureted engine so it's not only the misfires that I'm doing it for but also for the convenience in future situations and it also gets rid of all the smog stuff so I like that aswell
