first problem is all my signal lights work and the left side works in the dash ,but the rt. doesn't. did the normal stuff, changed bulb and even got another instument cluster from junk yard and had the same problem. 2nd problem is my truck is a carburated 7.5(460) w/ a manual fuel pump and a electric pump in the tank,I don't here the pump in the tank come on ,but the truck still runs -sending unit doesn't work but I can complete the circuit and the gauge shows full. Any help is appreciated.

 

Welcome to the site..

Try lifting up/back 'slightly' on the turn lever when right is selected and see if the indicator works.. The tank floats like to crack at/under the lift arm hook and the float fills with fuel and sinks to the bottom of the tank..
