help needed!-tank selector vavle problem
Quick rundown.
My brother called said his 90 250 7.3 diesel is dead on the side of the highway. It died when he tried to swap over to his other tank of fuel that was full. He was down to an 1/8 on the one tank. Now it won't start on him and the fuse for the fuel tank selector valve was blown. He tried putting a 30amp fuse in to get it to swap over but no luck.
Needs to know where on the truck the valve is located at.
Is there a way to bypass it?
If so which lines are which?

It's on the inside of the drivers side frame rail right in front of the forward tank. The fittings are all those plastic snap on jobs, so bypassing them will take some work. The return lines also go through it, so there's more work.

Why is he blowing fuses? I'd look into that problem first and then decide if the selector is bad. Had one customer that found the ground wire behind the radio was causing him problems. But your brother's sounds like he has a bare wire somewhere. Keep us posted.

I think the selector took a crap on him. The truck is still sitting on the side of the highway. He put the 30amp fuse in it and wacked it with a hammer and the guage started reading normal again. And when cranking he is now getting good fuel at the schrader valve. Batteries went dead on him though and he was 2.5 hours from home, so he ended up unloading the race car and driving it home.
He is now on his way back down with 2 fresh batteries and jumper cables hoping to bleed the air out of the injection lines and maybe it will crank then. Last night he drove down and got some fuel to put into the empty tank so both tanks have gas regardless which one its stuck on it should suck some gas now, he just ran it dry when it never swapped on him. We hope thats it at least.
