    I got a replacement valve and grommet for the vapor port, next to the fuel pump on the gas tank. Unfortunately, the valve is not secure and pops right off. I'm not sure if the valve is simply too small (diameter-wise), or if the grommet is configured incorrectly to hold the valve secure.

    The (discontinued) OEM Ford part number is E9DZ9B593A, and I have no idea what the part # is for the grommet. The valve I'm attempting to use is a Dorman fuel tank tent valve # 911-001.

    I see tons of vapor vent valves out there; none of them look like the original dual-nipple part. I'm getting ready to go harass some poor bastard at Autozone or O'Reilly's, and go through every vapor check valve until I find one that has a better diameter for fitting through the grommet and into the fuel tank more securely.

    If anyone has any experience with this issue, or has successfully managed to get something to work, I'd appreciate some info on solving this.

    I have looked for the OEM part on multiple sites - fordparts, ebay, amazon, summit, rockauto, etc. I am unable to find an alternate part anywhere, and am left with the option of attempting to find a junker and salvaging one - if there is an appropriate sable or taurus to be found in the area. The only related topic on this in the forums is one that I posted a while ago, and I was no help back then, so...

    Myotis, did you ever find an answer for this? I'm in the same boat. My mechanic gave me a slightly different # than yours above.

    Fuel Tank Vent Valve: E9DC-9B593-AA

    Issue was: after dropping tank in 2017 to replace fuel pump, I'd get an overflow beneath the car when filling tank up to the autostop point of a gas pump nozzle.

    Any solution better than my "don't fill it up all the way" solution is appreciated.

    Pretty sure these are still available from Ford, just under a different part number. I'll look tomorrow when I get to work. I came across these once a few months ago and wanted to get one for my 91 but I put it on the back burner.

    If Mr. Pride can find an alternative part number for the original vent valve, I'd go with that. Having the intended part will make things a bit easier.

    However, because I searched high and low for an alternative part, and found only jack shit, here's what I did (and it works as intended).
    1. Get yourself a Dorman 911-001 fuel vent valve from amazon link here.
    2. Also get a Ford fuel vapor valve seal - also from amazon - link here.
    3. At this point I can't remember if all the hose sizes line up, but I think they do

    Dammit, hit the wrong button and apparently can't edit... moving on.

    The main difference between the original and aftermarket vapor valve is that the original has two nipples - one heading up to the front of the car, and the second is the emergency check-valve. The aftermarket only has one nipple, so you will need to add the check valve for emergencies.

    I ran approximately 12 inches off the nipple, then added a brass T and attached the check valve - 90 degrees to the vent valve nipple - as close as I could. In hindsight a brass Y would have maybe worked better, but I live in AK - and we don't always have ready access to stuff like that...

    The nipple in line with the vent valve I spliced into a fuel line splice kit I picked up from Napa or Autozone. It's going to be 3/8" or 5/16", so measure the old line going to the fuel filter.

    I got an in-line check valve off the shelf at Autozone, ran a little hose from it after connecting it to the brass T, and used a screw-in hose clamp to fasten it to something so it wouldn't be constantly banging on the top of the gas tank.

    Keep posting here if you have more questions. I'll start digging around for pics I took while doing this.

    Here's the check valve I used.

    Used crimp-rings to secure all the hoses.

    An edit real quick: when I said "the line going to the fuel filter" I meant the line going to the vapor canister...
