Under Body Grommet

Guys, I did a search and don't even know where to ask this but here goes. I was working on my Tundra last night and was removing the rear seat. Thinking I had to remove a bolt from underneath on the drivers side passenger compartment, I pulled the rubber hole plug out and dropped it somewhere on top of my gas tank. Couldn't find or reach it. I could see the Styrofoam sound dampening material from the bottom and could see the hole from the top just down below the seat mounting plate. I was trying to find it on a Toyota parts site, but couldn't figure out what it is called. Any help on it would be appreciated. I really don't want to start pulling gas tank down for a rubber plug. Was thinking on replacing it.

 

I needed a new grommet for the front driver floor and ended up just going to the dealership. Talked with the parts guy and he ordered me the right part. Just offering as a last resort in case no one on here knows the part number.

 

Might need to take a pic so @Roman knows which one you're talking about if there are different ones in that area.

Can you bend a wire, coat hanger something and feel around? If your worried about scratching cover it with tape. And are ya sure it didn't roll somewhere?

 

Thank you Stig. That I believe is the correct part.

 

Not worried about scratching as this part of the body is exposed on the underside. I don't believe the coat hanger trick would do. You can barely get a hand in there and really don't have the ability to move around and fish for it. I did look around and did some rather radical maneuvers on my street to see if it would come out. No luck. For $4.72 cents, Imma buy a new one. Lol!

 

For $50 I wouldn't crawl around under the truck. That means I would have to get up!

 

Got an air compressor? Use an air hose with a blow nozzle to blow off the top of the tank. Blow from one end of the tank to the other, and angling toward the drive shaft to avoid getting the little plug any more firmly imbedded in the insulation.
