Audiowriter Glad you got it working!

[email protected] Thank you for your time.
I over complicated this, always when doing something for the first time.
It is a pain in the _ss. Ford could have moved it up the rail 12 inches forward.
that would have given all the room needed.
It was just a pain to get to every connectors to pinch them so I just disconnected and connected.
Yes I am soaked with diesel. But it is done and it works.
symptoms for any following:
1. switched tanks
all fuel gauges went past full no air conditioner
disconnected tank selector valve air conditioner works
2. bought after market selector valve (Orion) ~$70 works great direct fit
NAPA carries the clip for the fuel lines

Thank You for Your Time!
sometimes you just have get dirty and do it.

Audiowriter I never had that issue. Are you sure you are matching them up exactly?
However - it may be the particular brand of valve...?
The individual tank "send" and "return" lines must be matched from the front of the valve - to the back of the valve. There should be 4 ports / lines on the back of the valve and 2 ports / lines on the front.

The 2 on the front go to the motor (fuel pump and return - not sure of which is which...)

From my memory - I can't remember which of the 4 ports goes to which line on the back - (front tank suction and return - - back tank suction and return.

[email protected] it seems that the replacement valve 3/8 valve and 5/16 are reversed?
looking at the clips that came off of each port.
does this sound correct?
i would think think that each hose will only fit the correct port
did you encounter this?
I would think that by taking off two hoses at a time starting with the top and replacing them to the new
selector valve this would stop any confusion. Not much play in the hoses.
Am i correct to assume so?

Audiowriter Clamp off the hoses from the tanks or fuel will run out before you get the hoses off the old unit - and on the new one.
(I used 2 pairs of vice grips - tighten them "just" enough to smash it closed - don't over tighten!!!! there is no pressure on the lines - gravity siphon is all you have to stop)

Make sure you get the RIGHT HOSE to the RIGHT NIPPLE - make sure the change over is exact - or it will cause problems.

[email protected] thanks
the price difference is so much I thought I might be missing something
Bought the after market
any suggestions on the install?
I would think the fuel tank and diesel spills would be the worst part
thanks again

Audiowriter I have used a couple of the $80.00 aftermarket ones from O'Riley Auto parts and never had any issues. They lasted several years / miles and were doing fine when I sold the trucks. I have no idea if they are still working - now - several years later.

after market fuel tank selector valves

the difference between OEM and the after market is extraordinary.
do the after market work as well?
i have seen some people say the wiring is different.
i have 1997 7.3 power stroke
I have seen any post on how difficult it is to change out the selector valve
