Okay. I have heard that Napa sells a 6-port tank selector that can be rigged to work on our trucks. Can anyone tell me the part number and/or give me an idea of what work it requires? I understand how the stock one works.

 

I just replaced a selector valve on a '76 chev. I have a difficult time finding one for that model. I did discover each valve has a pretty good description of how to wire them up included in the package. I'd suggest going to NAPA (or whoever) and having them pull the part and look at the diagram.

 

I have an 85 E 350 6.9 replaced the selector vavle with one from Advanced auto
Believe it or not it is an AC Delco switch .... ACD # U7001 GM # 12336291


Works fine in Mine
