Dual Tank Question

[1981lowrider]

I have Dual tanks on my 81 shortbed. i was told the passenger side only worked. I got a new selector valve and it The dual tanks still doesn't work. My question could it be the Switch itself the one on the dash? Or is there something else? Just want to get both tanks working. I searched the threads for this topic but couldn't find anything. Any help is appreciated!!

Could be the switch on the dash. One time on my 77 I put in a new dash switch and valve on the frame and I still had nothing , it turned out that the valve on the frame was not grounded well , (to much paint) , so I sanded some paint where it mounted and put it back on good to go.
Also check all your wireing

Also you may want to check the other tank if it has been not used for a long time , I have seen the sock at the pick up tube totally plugged off before
