Re: [Chrysler300] 1964 K Remote Brake Booster Vacuum Line and Manifold Check valve.

Thanks Carl. In doing a closer inspection on the check valve it appears that is has been replaced at some point. The check valve has Bendix with a part number 379928. From what I can find this crosses over to Mopar 207934 which is for A body line according to the parts book. The valve stills seems to be functioning (just faded and a bit brittle) but I wonder if there is an impact to the proper operation. Especially since the K has a different part number. 
Also thanks Bob for making the correction to the Newsletter!

Ram K same as the J.  Dorman 80190 will not fit.  Original check valve and booster inlet is 3/8” as you state. Vacuum hose to booster is 3/8” i.d.   I had to reuse the original check valve.

Hi to all


I had the remote brake Booster rebuilt and I am in the process of re installing. It only makes sense to also replace the vacuum line and check valve from the manifold as I can only guess how old they are. Original?  In reviewing past club news letters I ran across a tech article in Newsletter #20 from 2015. It is stated that a Dorman #80190 can be used in place of the original check valve and shows the 1/2 inch side of the check valve for the line going to the booster. So I purchase the valve and 6 ft of 1/2 line without double checking what I took off. Now that I am out trying to get this all together it looks like the original check valve stems (both of them) and the booster inlet is 3/8. The article did not mention having to do any modifica tions. The only original hose that is 1/2 inch at the booster is the hose to the filter under the battery tray. Has anyone else had to replace the check valve? If so what did you use?  Thanks in advance
