I have a '05 standard 4 dr. short bed. Where I have looked on line it seems they don't make the larger tank for my truck. Any ideas for me???

 

fuel tank vent mod will get you additional 3-5 gallons

 

OK, so how does this vent mod. work??

 

Years ago, I wanted additional fuel in my Ford Econoline van - short bed. There was no ready made larger or additional fuel tank available.

I measured the space I had available, and cruised the bone yards. I found a factory tank that fit, fabbed some mounts and a filler neck, and used a fuel switching valve and control switch from a Ford pick up.

It wasn't difficult work at all, didn't cost very much, and added an additional 22 gallons.

My wife still managed to run out of gas.

 

The vent mod allows you to completely fill your stock tank... and fill it quickly. There are a few kits available, like this one from Diesel Max or this one from Glacier Diesel.
If you're crafty, it's also easy and inexpensive to make your own. Here's what I did:

What does that do Mark? Let you fill up the filler neck too? I'm a touch confused...

 

msiminoff,
Where did you come up with your parts from? I really like the way you keep the stock vent tube as well.
Thanks

 

The fuel tanks on our (diesel) trucks are the same tanks that are use in the gassers. However gasoline expands more than diesel with temperature changes so the tanks are designed allow additional space for that expansion.
When you vent the expansion area you are able to quickly and easily fill it with diesel fuel... and of course you can fill up the neck too.

The parts are all fittings from my neighborhood hardware store (the 3/8" fuel line is from my FLAPS). I did have to do a bit of drilling, tapping & turning (that bulkhead fitting originally had whose-barb on it) to assemble all the pieces the way I wanted them.

Cheers

Shows shortbed extended and crew cab, Id call em and see.

 

titan tanks look really nice also

 

I bought the vent mod kit from glacier about 5 years ago. I have enough extra capacity that I don't feel the need for a larger aftermarket tank. Not to mention I can't justify the cost of the larger tank: They typically go for upwards of $1000

The vent mod kit cost ~$40 Added about 5 usable gallons to the tank, and really shortened filling time. I used to have to slow fill the last 5 gallons, taking 20 minutes to fill the tank. Now, it takes me about 5 minutes to fill the tank and I can slow fill the last gallon up to the filler neck in another minute. I have 36 gallons usable, before the low fuel light comes on.

I'm assuming you would want your tank to be empty as possible in order to remove it? Also how do you remove your tank? So you were able to add an additional 22 gallons to your 34 gal. tank? When you go this route, can you still walk away from the pump and it will still shut-off automatically or do you need to stay put so it won't keep flowing all over the ground?

 

Since working with fuel and on dispenser's for a living, you should NEVER walk away from a filling vehicle. You are relying on some mechanical part, in this case vacuum operation to hopefully stop the flow of fuel. Just some advice.

From what I got, I believe he added a second tank to his other tank. If I'm wrong please correct me.

 

Raycer you can also get an aux tank that's in a diamond-plated toolbox that you put into your bed. I have one that's plumbed via an electric pump that's actuated by a dash switch that fills the main tank through the vent line as it comes into the fuel fill tube. It works really well, and between my 35 gallon aux tank and my main tank I fill up about once very 800-900 miles now.

 

If I read between the lines, you don't want an aux tank in the bed to take up space. If you can have the aux tank, you can gain a lot of fuel for a minimum amount of money. RDS (go to Northern Tools to see them) has a great assortment of in bed tanks. I have their low boy (I pull a fifth wheel) that is 50 gallons plus a small tool box on top. It is plumbed in using gravity feed meaning no pumps, no electrical switches, easy to do - - and before we start, IT IS legal the way it is done. ... ....This gives me around 80 to 85 gallons usable meaning about 1500 miles before I have to start looking if I am running solo, or 900 or so pulling 16,000 pounds behind me. Good quality and way under $1000. I have a pic in my album if you want to see the installation plus a write up on the installation in the tech files.
