Fuel return tee kit to fit on the top of Stanadyne Diesel Pencil Injectors This item is OEM Stanadyne brand Kit includes 1 each: aluminum tee 31288 steel nut 17720 Subs to 24187 grommet 17721 Installation tips: 1. First unscrew the tee and set aside. 2. “Gently” clamp nut in to a vise and force injector through old grommet by pulling, twisting and WD40, do not loosen any of the nuts on top of the injector itself, this could change settings. I guess one could pick out the old grommet with a probe but would be tedious. (Use care not to warp nut with the vice) 3. Slide on nut without the grommet and then poke in new grommet. 4. Slide nut and grommet up and thread onto the tee, the assembly does not have to be very tight to seal. Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4
