Can't believe it. I am stupid
Man...I am sooo PO'ed right now.
Got a new tune from JDM, and was getting ready to install it when the thought hit me that the last time I put gas in my car, I think I put 91 octane in there. Call JDM, they tell me to make sure I have a min of 93 in there before I start the car, which would mean draining the tank, or putting some race gas in the tank to "mix" with the 91, bumping it up a few octane numbers.
Soooo..I go and get 4 gallons of race gas, put it in, and get ready to start the car. Phone rings..its one of my buddies..we yap..and during the course of converstion he says "I thought all race gas was leaded".
Long story short..called race supplier, turns out the gas IS LEADED, at least according to the girl who answered the phone.
Now, the good news is, I have not started the car. Theres roughly 1/4 tank of gas in there now (which I would assume is mostly the race gas).
A Ford technician told me to pull the fitting at the fuel rail, jumper the pump relay, and pump the gas out. Refill with new gas (about 5 gallons), and repump out. He said I could also pull the backseat and the fuel pump and siphon any remaining leaded out if I thought the pump didn't get it all. He said the fuel pump would pump out 99.9% of the fuel.
Then change fuel filter, and put 93 octane in.
Question is...will that remove enough of the leaded to not harm my converters? I know leaded won't hurt the motor, but it will destroy O2 sensors and convertors.
Ford tech said it would take at least a tank of leaded to do any damage. I have read trace amounts of lead will mess it up.
Need some opinions guys.
Help?

If leaded fuel concern is ONLY for the converters, I would just remove as much as reasonable and install 93. You will not hurt the converters with the small amount of lead in the filter and lines.
You should have a "bad gas" tune in your programmer for just such an issue though. What if you are out on the road and have to go to Sams Roadstop Gas 'N Grub?

EDIT: I didn't see the O2 sensors thing, but I still HIGHLY doubt would cause damage. I bet they don't even read lead as it is not in any acceptable D.O.T. fuel. I would recommend you confirm they would be OK or just remove them for a tank. Then, re-install them and clear codes.

First off...Not all race gas is leaded. Where did you get it? Usually the higher octane stuff like 110 or 115 is leaded. 104 is not.
If you did manage to get some leaded gas, it's not the end of the world. Drain the tank and fill it back up with 93. If you're really ****, you can change the fuel filter, but believe me, it's not as big of a deal as you're thinking.

After reading your and Jazzers reply, I feel better about the leaded fuel situation.
I has a couple guys at the Ford dealership tell me to drop the tank and flush it out completely.
I was thinking that flushing it out with some unleaded and gassing up as normal would be fine. Just was worried about he trace amount of leaded left in the system.

Bummer. Pro-110 is leaded.
Again...It's not that big of deal. The worst that will happen is that you'll burn up the O2 sensors. And then you're out $60 and about 15 minutes of work.
That's an inexpensive lesson in my book.

I should have asked, and I deserve the fallout from it. And you are correct, it IS the Pro-110.
The O2 sensors I can live with. You don't think there'll be any damage to the cat-converters?
Honestly, its worth 20 bucks of gas to thoroughly wash the tank and lines out to minimize any leftover leaded. I am also going to pull out the fuel pump and make sure the tank is as dry as possible before refueling.
I think if I do that, there should be no left over leaded.

Unclemilti, sorry to hear about your situation. On the other hand, the way you set up the story and posted it, I have been laughing for 10 minutes. Freakin Hilarious!
I'm sure you'll flush anything harmful out as suggested. Good luck, Erik

You should be fine. I would maybe dilute the fuel some more (using 91-93) and just let it burn. For the small amount you have in there, I would not be concerned. I think it is too small of an amount to hurt the converters. The O2s may or may not be affected. I would say no. What happens is the lead contaminants/build up on the sensor.....killing it. If you do nee to change them......use ONLY Ford Motorcraft replacements!!

You're worrying too much. Just drain the tank. You don't need to dry it out. Even if, let's say there was a gallon of leaded left in the tank. By the time you fill it back up with unleaded, it would be so diluted that it wouldn't do any damage. You just don't want to run straight leaded through.
