I have a 1989 F-350 7.3 IDI 4x4 ex airforce ambulance. This truck came originally from Ford as a Chassis Cab. hence the chassis might be different as from a regular truck.
My truck has the forward and rear diesel tanks, front is metal, rear is plastic.
I had to take off the ambulance body, and replaced it with a flatbed.
The goal of my flatbed is to keep the center of gravity as low as possible, and the frame of the flatbed is from rectangular stock (I think you call that in USA?) since I calculated the strength of the flatbed, I can't compromise the frame by drilling big holes in there to pass the filler/filler hose through.
I did mount one of the original fillers under the frame, The result is; I can't fill it there, there is no flow towards the tank, the filler is too low.
Also I prefer not to have a filler on the side, so that if the deck is full with payload, I still can fill up.
I'll have to try if I can place some pic's here, that makes things more clear.
I'm open for all ideas! thanks for the help.
this is the rectangular stock I used
this would be ideal, but is impossible
here you can see that there is no flow towards the tank if you mount the fillers under the frame
again no dieselflow towards the tank by this filler position
the space I have under the deck
filler mounted under the deck frame, this give big problems when you fill her up!
I need an alternative.

Reason: adding the pic's
The way you have it setup you are trying to push fuel uphill. The orginal location would best. I understand wanting to keep the bed loe,but it looks likes it too low. You may have other problems down the road like tires rubbing when load. The bottom of your bed should be just above the filler necks. Also you tubing look small for a flat bed. I would think you woud want at least 10 cm stock. Remember you need tiedown points also. Good luck
In a certain way you have reason, I did have the rails calculated for a payload of 2.5 metric tonnes, with a security of one tonne, therefore I can't drill or otherwise make holes in them, that would compromise the construction.
I 've seen other constructions as you said with another beam underneath, but due to height restrictions on the peage (tollroad) and trying to keep the weight as low as possible to make it possible to load as much as possible.
And I tested the torsion of the deck with 2.5 tonne payload and lift one wheel with a forklift, and it didn't touch the deck.
But for me the most important is; to have the truck registered! after that I make some modifications to the deck.
Sound like you did a lot of research and testing. Was not criticizing the work it looking good. Now back to the fill problem, the has fuel to flow down hill to the tank. One thing you might consider it is a little usual and will require geting creative with the hoses. Mount them thru the bed floor with small covers to protect them. One big problem with that would be if you loaded something on top of them no way to refuel till unloaded.
Fuel has gone way up over here. I currently paying around around a $ 1.00/liter (usd)
If possible I try to avoid that, it would be pretty stupid to empty the tank and to have to offload the truck in order to fill up, imagin how the people will laugh at you when they see that (I would)
actually I'm thinking one way or another to make the hose longer and get a upstanding fillpipe just near the drivers cab before the deck starts.
I have to think about the details.
does anybody here know how this works? there is a double hose to fill up, I assume one is for the diesel, and the other for the air to escape?
and how could I make something that (in order to minimise the outer diameter from the hose to fill) separates those two?
(I hope you still understand about what I write?)

last question first yes I understand what you are talking about.
there is a thread about modifing the vent system.
i can remember if I took mine out or just shortened them. It was a fakely system from the start. If something I write does not translate to French ask me to reword it.

No problem, I've got more difficulty with writing French than the English language
Was not sure. We had an exchange student once from Norway. At first she had to translate English to Norwegian, but as time went on she did not have to. She was fluent in 7 languages
7, no, but I manage 5 languages, though I find writing in French and German still difficult reading ans speaking is no problem. I think that with so many languages finding the correct word for a certain situation is the most difficult, I also noticed that sometimes you use automatic a "strange" to that language word, for example you try to write or speak English, and you only can find the German word for that situation. That can be very awkward.
If I know someone is from a differnt county I try to use words that will translate and try to convery US mearsuement to metric. Puerto is really strange the exit signs are metric but speed limit are mph 8nstead of kmp
yeah, maybe they still don't know if they are all over to metric or not?
for me it's ok, just write as you do in the states, if I don't understand I'll ask.
(I would)
