SOURCE: gas over flow on dual tank system

If they fill separately and have a switch to select tanks, then simply just use whichever tank you want to. If they are connected, you will have to drain both tanks, remove the connecting pipe and plug each tank. Make sure you are using the one that the pickup is in if there is only one.

SOURCE: Dual tanks on 1990 Ford F150

It should not cause no problems but instead of removing the tank leave it in the truck take out all the fuel in the tank and jus discontinue use of it. This will save you alot of time and trouble and i also suggest that if anyone besides you drives this vehicle then i would put a locking gas cap on it so it cant be accessed at anytime except by you.

1988 Ford Ranger XLT 4X4. Newly purchased dual fuel tank has an internal fuel pump, an inline pump, a fuel tank selector unit, and what looks like a second fuel tank selector unit (which is leaking).

The black reservoir/fuel tank selector unit you are referring to is the fuel tank switching valve, which is designed to switch between the two fuel tanks in your 1988 Ford Ranger XLT 4X4. This valve is responsible for directing fuel from the selected tank to the fuel pump and engine.
The second fuel tank selector unit you mentioned (part number 5sv2k) is likely a replacement part for the original fuel tank selector unit. It is not intended to replace the fuel tank switching valve.
The dual fuel tank system in your Ford Ranger requires both the fuel tank switching valve and the fuel tank selector unit to function properly. The fuel tank selector unit allows the driver to switch between the two fuel tanks, while the fuel tank switching valve directs fuel from the selected tank to the fuel pump and engine.
If the black fuel tank switching valve is leaking or malfunctioning, it should be replaced to ensure proper operation of your dual fuel tank system.

Where is the Purge Solenoid located on a 2006 Ford Explorer XLT?

The purge solenoid on a 2006 Ford Explorer XLT is typically located near the engine, often near the fuel tank.
To locate the purge solenoid:

  1. Pop the hood and locate the engine.
  2. Look for the fuel tank, which is typically located near the rear of the engine compartment.
  3. The purge solenoid is usually located near the fuel tank, often on or near the fuel lines. It may be mounted on a bracket or attached directly to the fuel lines.
  4. If you are having trouble finding the purge solenoid, you may want to consult the vehicle's repair manual or a diagram of the fuel system. You can also try searching online for images or diagrams of the purge solenoid on a 2006 Ford Explorer XLT.

Where is the fuel transfer valve on a dual tank 1993 Ford F150 located?

From what I can find out Ford did not use a fuel transfer valve in 1992. They ran both pumps to a common fuel line and used one way check valves to keep one pump from filling the other tank while keeping the entire fuel system pressurized. Your tank selector switch is actually switching pumps off and on, not a transfer valve. The problem Ford had was the one way valves failing causing one of the tanks to overflow. They have an external one way valve kit to solve this problem, but the valves are about $85.00 each.
