Hi guys, my name is Tim and I'm looking for a little help pointing me in the right direction. I thought I'd chime in here as your'e on the subject already. I have a very nice all original 85 F-250 4x4 Diesel 6.9 with dual tanks that just recently stopped switching from tank to tank Any ideas? Be gentle as I'm sure this question has been asked before. Thanks and sorry to barge in.

 

Welcome to FTE, Tim!

You're right, you shouldn't barge in on other people's problems, that's considered rude and is called "hijacking a thread."

So, I created for you a brand-new thread with YOUR problem and a descriptive title so as to attract those who might know; I believe the switching valve is different on diesels but am not sure, somebody will now for certain, though.

I apoligize, I am a member of two motorcycle forums with this format but rules seem to differ between them. On the larger one I would have been corrected for starting ANOTHER thread on the same basic issue I'll get the feel of you guys soon I hope. Thanks fer the fix P.S. When will I be able to manage attachments?

 

More than likely you need a new switching valve. The stores sell a universal one that needs a little bit of modifications to make it work, or I believe Ford may still sell the correct one, but they are proud of it and their price reflects that.

 

Thanks for the reply, Is it fairly easy to get to or is it the first part they built the rest of the truck around?

 

It's on the inside of the frame, on the driver's side, in the middle area of the truck.

 

Thanks! When I can post a pic of my 85 I will and think you may be impressed. I also have a 72 3/4 ton Ranger in primer thats ugly as hell but she can't be killed

 

No need to apologize, this is just how it works here. You did the best you could, what you thought was right.

About your tank switching valve, well, you should verify this is the problem before throwing parts at it but it'd be a pretty good guess that that's the problem.

You can use a multimeter or test light (if if you don't have those, get them) to see if you have power at all the right places at the right times.

I don't remember what the colors of the wires are and where to probe, hope somebody who knows comes in.
