Removing Tidy Tank

Hello Everyone!

I am am a new owner of a 1988 f250 7.3IDI! I am really happy with it so far and have found this site useful over the last few days since I have purchased my truck, so thank you.

I would like to remove the tidy tank that is installed but I would like to know how a stock system is set up. Currently it is a spider web of tubes going to two three way T valves that have levers by the front seat.

Can anyone explain the path way of fuel from the two saddle tanks to the engine so that I can reconnect the tubes going to a unit that is bolted to the chassis under the extended cab? I am not sure what this unit is called.

Thanks for for your help and patience! Any other questions you have about the truck I would be more than happy to answer. The only thing I have done so far is flush the cooling system and added the proper coolant to prevent cavitation.

thanks!

welcome to FTE.
i have no idea what a tidy tank is.
but these trucks came from factory with an electrically switched tank selector valve.
one supply line, and one return line from each tank into valve, then one supply and return lines to engine from valve.
so pretty much any lines going into a manually switched valve are add on and can be removed if you want to go back to stock

“Tidy Tank” is what all my co workers were calling the huge reserve tank that was installed behind the cab in the bed.

Mechanic said it is was just gravity fed but I am thinking they have it spliced into each of the supplies from the saddle tanks and now from what you have explained I understand what part of the fuel path I am dealing with.

I will I’ll do some more research and keep an eye on this thread, thanks for the helpful reply!

Also so thank you for the welcome!

Ok did some research quick and it is indeed the tank selector valve where all the splicing has been done.

in a nutshell the two levers by the seat are to control the feed from the tidy tank into the preexisting lines. Each lever is on a T valve and now I am starting to see the path.


THE NEXT QUESTION!

How do do I figure out which is supply and which is return from each of the tanks and the engine?

supply line will go to the fuel pump on the passenger side of the engine. return line will come from the top rear driver side of the engine.
finding the lines on the engine and tracing them back to the valves is the only surefire way to identify them.
if i remember correctly, the supply line is also larger than the return line.

Thanks! That makes sense from what I read about fuel pumps, I will do some digging to find out about which valves are which on the selector and which are which for the fuel tanks.

I did the same thing with my truck when I first got it but luckily it wasn't spliced into the factory fuel lines. At 105 gallons this thing was pretty big but now "I got an 8ft bed that never has to be made" Throw up some pictures if you have time. We love that sh** Two decent size fuel tanks seemed plenty enough for me.
