Default Tbi rebuild

What is the plastic/rubber grommet on the wires for the injector pigtails? Not the insulators on the injector plugs but the grommet that slides into the tbi housing. I can’t find a replacement anywhere. If y’all know where i can get one let me know. I’ve got a glob of high temp caulk on it for now but that ain’t my style.

Welcome from Florida. Most hardware stores, Amazon, Ebay, etc. sell grommets. I have bought them from Home Depot, just have to match the style and size.

hi. Thank you. To be more specific. I chose the word grommet as the best example of what i could compare the piece I’m searching for to. It’s actually a small molded square block shaped piece that slides into the front of the tb. It has the injector wires going through it. It got pretty well vaporized when i grabbed it with needle nose to slide it out. I could find a small block of rubber and make my own but i assume the real deal is out there somewhere. Any ideas on locating the actual part?

Maybe you can use some silicone to seal and hold the wires in.
