Fuel pressure test port cap
Hello,
Does anyone have the part number for just the cap that goes on the fuel rail where you test fuel pressure? Thanks, Bill |

FYI - I think an -4AN cap will screw on there.
Mine dropped down into the valley a couple of years ago. I think I had a blue anodized cap on there for a while, and later put a fuel pressure sensor there. |

Good information, thanks for your help!

When I went through that search a few months ago, until a kind soul gave me one, several suggested going to a local HVAC shop - it being an AN fitting.
Good hunting!! |

If you're near an ACD jobber or GM dealer you might try 214-1044 or 25532662. I've never tried this but I don't know why not. With whatever you buy be sure to check inside the cap for the o-ring seal. I think that generic -4AN caps may not have the seal.
If you try the GM I'd be interested if you post back and mention your thoughts. I've always intended to but haven't had the need so I never have. |

Thanks again for the information. I ended up at Lowes and bought part number 40-4X P. For $2.00, I have a cap that will work although it isn't NCRS!
Thanks again, Bill |

GM did not issue a part number for the metal silver cap used on the LT5. The cap was available in a service kit that included a new valve. The kit is PN 17112219 discontinued by GM.
