Where is the reserve switch on a 1985 yamaha viargo

Many motorcycle models do not have a reserve if they have a fuel gauge.

If you do have a reserve selector, it will be part of the device bolted to the bottom of the tank that the fuel line is attached to.

I think though that you have an automatic shutoff that only allows fuel flow when vacuum is present (eliminating the "On/Off" selector), a fuel gauge, and no reserve system.

My f350 1997 will not run on the rear tank . how do i go about finding what the problem is?

well, first, to find out if its the in tank fuel pump or the tank selector valve, the cheapest and probable easiest thing to do is find the selector valve under the truck and switch the incoming fuel lines. front tank to rear tank inlet, and vice versa. If the truck still doesnt run, you either have an electrical delivery problem to the in tank fuel pump or a bad fuel pump. If after switching the lines, it does run, then you need a new selector valve

1992 f 159 dual tanks fuel guage not working

You will need to remove the wire for the sending unit on the tank and ground it to the frame with your selector switched to the tank you are working on and the key on. If gauge comes up to full then the sending unit is bad and gauge is good. Repeat process on other tank. The fuel tank switching valve on the frame also switches the wiring signal from either tank for the gauge. If no change with first test you will want to check the valve.

Fuel gauge does not work

It sound's like you have a graound problem with the wire harness from the fuel tank. Check the connection from the tanks to the fram. Good luck.

No fuel getting to the engine

Sometimes but what controls the switching is the selector thats right in front of the first tank closes to driver.Check your fuses first and have someone listen to the fuel pump and selector to hear any movement..You can also check for power at the selector if no power then follow wires up to rule out bad wires and fuses and relays..Also the thing you think is another pump is the tank selector.When you push button in dash thats what switches it to the tank you preferred..

Fuel Tanks reversed , Gauge not reading?

The Ford trucks were recalled for the tank switch replacement. Somehow the switches would pump fuel from one tank to the other. This would cause the one tank to overflow and or result in a fire from hot exhaust temps coming into contact with the fuel. Check the dash tank switch. It is probably bad.
