Fuel Cell for a 99 GMC Sierra

So, I wanna put a fuel cell on my truck finally. I want it to be under my bed in the back behind the axle. I've seen some super clean ones done out here and I was hoping some one wouldn't mind sharing there dimensions with me. I want to put the breather back in it and use the factory pump/sending unit. I plan on doing a raised bed floor after I finish. I'm looking for it to be roughly 20 gallons. So if you have plans/dimensions and wouldn't mind sharing them I would greatly appreciate it. Also, a couple pics would be nice. It's supposed to be a surprise gift to me from my wife for my birthday. Thanks in advance.

Bump.

Bump. Someone gotta be able to help me out.

When i did my buddy Scotts 03 Sierra he ordered a custom cell from Devious. I do not recall dimensions but we gave him the length and width and told him to make the depth the same as the raised tank they make for the factory unit. Here is some pics:

Thanks man. That's a nice cell. Do you recall the volume??? I'm looking for something just like that!!! I appreciate the help too.

if your using your stock pump and sending unit, you want your cell as deep as your stock tank. my stock tank was i think 12in deep where my pump was, so i got a 12in deep cell so my pump would go to the bottom of my cell.
here is how i did mine http://www.customdakotas.com/forums/i-have-question/9401-jeep-fuel-pump-adapter-ring-5.html

I have a fuel cell that I would like to sell or trade striaght across for the stock gas tank. the only thing is that it goes in the same location as the stock one does and it's smaller then then the stock ones. if interested let me know

justin im going to kick you in the liver when i see you lol...you know we build cells all day everyday little niglet

Thank mike!!! You still on leave???
