Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE). Review: Great purchase. - I purchased for my 2006 Workhorse chassis under my Winnebago RV A class. Functions perfectly. Review: Used this to fix the vents on my 1991 Jeep Cherokee XJ - Finally fixed my a/c vent issue in my 1991 Jeep Cherokee. I tested all my vacuum lines with a vacuum pump and there was no leak, but I was missing the check valve so when the manifold vacuum was reduced under heavy acceleration the air would stop blowing out of the front facing vents and start blowing through the defrost vents. I previously brought a Dorman 47170 which was listed for Chrysler, Dodge, and JEEP and it was defective right out of the box (passed air both directions). I decided to give this a try and glad I did. Was a tight fit on 1/4" hose. Now my forward facing vents continues to work when I'm on the freeway and does not default back to the defrost vents. ## Features - Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE) - GM Genuine Parts are designed, engineered and tested to rigorous standards, and are backed by General Motors - GM Engineers design and validate OE parts specifically for your Chevrolet, Buick, GMC, or Cadillac vehicle - GM regularly updates production and service part designs to integrate new materials and technologies - Fit type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000C982H2 | | Best Sellers Rank | #77,739 in Automotive ( See Top 100 in Automotive ) #1 in Automotive Replacement Distributor Check Valves | | Brand | GM GENUINE PARTS | | Brand Name | GM GENUINE PARTS | | Customer Reviews | 4.6 out of 5 stars 416 Reviews | | Exterior Finish | Machined | | Global Trade Identification Number | 00021625041773 | | Included Components | ACDelco - Cruise Control (Slp) (14047619) | | Inlet Connection Size | 0.25 inches | | Inlet Connection Type | Socket Weld | | Item Dimensions | 2.1 x 1.3 x 0.9 inches | | Item Type Name | ACDelco - Cruise Control (Slp) (14047619) | | Item Weight | 4.54 g | | Item dimensions L x W x H | 2.1 x 1.3 x 0.9 inches | | Manufacturer | ACDelco | | Manufacturer Part Number | 14047619 | | Manufacturer Warranty Description | 24 Month / Unlimited Mile Limited Warranty on parts sold on or after 04/01/18.

They are for 1/4 **Q: Which way is this valve installed? I understand one way allows the vacuum to be pulled through and one flows freely but dont know which way to install** A: This device is a one way check valve used to permit vacuum to be applied to a vacuum storage tank. Think of vacuum as the opposite of air pressure and you will understand. The way to tell which way to install it is to put your mouth on one side and see if you can blow through it. If you can that is the direction that the vacuum will pass. The other way you can do it is to put your lips on one side and see if you can suck and get air to come through. If you can that is the side that should be connected to the vacuum generation device such as the intake manifold of your automobile. **Q: Are the inlet and outlet the same size?** A: yes, exact same size **Q: Does thi fit Saturn 2003 l200** A: it will fit a 1/4 hose ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great purchase. *by J***M on August 24, 2026* I purchased for my 2006 Workhorse chassis under my Winnebago RV A class.
