ACDelco U7000 Professional Fuel Tank Selector Valve

This tank selector says it works only for the non return system but it works with or without return. Just need to take the rubber plugs off of the return lines. Save yourself money and buy this one if you have the return lines.

If you are replacing a OEM unit on a square body GM this is the unit to use. Just make sure that you identify your fuel lines correctly before installing the new valve. Is a pain in the butt to change this out so you want to make sure you reinstall the new unit correctly. Also check to insure that lines are secure and tight. Should give you many years of good service.

Nice AC Delco product for my G.M. vehicle. Fit is exact and price was fair.

Worked as it should on my 89 F150 5.0

Easy install. Works just like the original that was on my '85 GMC when I bought it in '91... The original lasted until 2021..Hope this one gives me another 30 years....JB

Installed it on an 81 C-30 with no problems but after finally installing a 2nd new side tank I found the valve is not working. There is fuel at the valve inlet but none coming thru the valve. Going to hook up one tank and forget it. Maybe a manual valve would work. Will let the new owner fix it.

Ordered for an exact replacement of the Delco valve for dual diesel tanks I had installed 16 years ago. It connects 2 tanks and has 2nd set of ports to vent the excess diesel thru cooler and back to the "respective tank". Great valve for 2 tank diesel use.

I used this to flip between my two tanks in my 1975 IH Travelall. The valve has two sets of ports independent of each other - 3/8" and 5/16". As all my fuel lines are 5/16", I used those and capped the 3/8". I'm running of the mechanical fuel pump so I am not using this to select any electric fuel pumps. Simply using two wires in with a DPDT reversing toggle switch. Each tank has a filter after it before it comes to the selector valve per the manufacturer's instructions. This provides a nice visual verification of flow as well.
