fuel tank switch emergency!!!!!!!

[04mach1]

hey guys is there anyone online that i could call and talk to about the switch located on hte drivers side frame rail at the rear of the cab for my 93 diesel f350????

problem is i have the switch in the truck and i redid all thefuel lines on it... now the truck wont run off of the front tank but will off the rear..
i was wondering if i could call someone while they take a peek under there truck to see if the line that goes to the motor comes out the top of the switch or the bottom..

i think i maybe have it coming out of the rear tank section of the switch which would make sense on why it only runs off the rear tank..
again would like to have someone on the phone to look under their truck while i explain in detail what it is need them to look at..

i have looked for the diagrams on the net and have come up with nothing and my old lines just went out to the garbage yesterday

PLEASE!!! anyone?
thanks

Does your truck have a verticle selector valve or horizontal?

i think its horizantal

it has the front tank go in the end opposite the larger portion of the valve and then a set of lines out the top and bottom.

I have 88 ford 460 Gasser service rig that dose the same thing.And i have never change any lines it also only draws out of the rear tank, it use to work.i have pulled the switch and it check out.i will have to watch this thread.It mite be in the control valve that moves it from front to rear.

The bottom hoses go to the rear tank and the upper ones go to the engine. The three closest to the frame rail should be supply, and the three outside ones are return.
