In have duel tanks on my 1984 ford ranger 2.8l v6 i put in a new fuel takn selector valve and i cant get it to swith from the back to the front tank. I noticed inn my book there is a fuel shuttoff selinoid> this is bad wouldnt it not allow any feul from the rer tank snd only from the front tank. Also where might this fuel shutoff selinoid be located at

The switch that you use to change tanks is probably faulty - the switch supplies power for the sending unit in the tank, and to the transfer switch for the gas lines - use a meter to check it
