Gas Tank
I have a 1985 f150,302,dual fuel tanks,2w drive,fuel injected. My problem or question is can I eliminate the small tube inside the larger gas filler hose. I think the small tube is some sort of air vent when filling tank with gas.
Thanks for any and all help.

It is a vent ... Fuel goes in and air goes out ... Otherwise you would be all day filling ... Kinda like pouring from a gas can with the little vent closed ... real slow ... Open the vent and out she pours ... Some tanks can be vented with a seperate fitting installed on the top of the tank ... But to do that you need to empty and drop the tank, flush the fuel out (don't want vapors) and drill a hole ...
Are you thinking of eliminating the vent hose for some reason?

vent hose
Magusjinx
I am replacing my 19 gallon long center tank. [you do not want know what happened to the old tank] I want if possibly to get rid of the vent hose. So what type of vent fitting do I need and where can I get one. I am also assuming the hole that needs to be drilled should be drilled at the highest point on the tank that does not interfere with the tank mounting.

You could replace your tank with OEM ... Or you could look at places like Summit Racing and go for a fuel cell ... They come with vents and roll-over valves ... There are many other outfits but that is the one that comes to mind first ... You might even look into a fuel tank/tool box combo that fits cross-bed ... However I would check your local (state) laws as far as where and what you can use for a primary fuel source ...
I have been toying with the idea of a flatbed which would give me room for a pair of 22 gallon poly tanks by RCI ...

If the vent stays clipped inside the larger tube, it works fine on a gas truck. If it becomes unclipped, it falls down and the fuel splashes against it and makes the station pump cut off all the time.
If you try to make another vent in the tank, it opens up another whole can of worms. The only spot really to add a vent is the emissions fitting, and it runs up to the charcoal canister. So you would have to eliminate that system, and then wherever you vent you are going to get a gas smell.

vent tube

So what you are saying is I can leave my small vent tube out when I put my replacement tank on my truck right. By the way the tank I am putting on my truck came off a junkyard truck.

So if your vent tube is gone gas is slow, and if the tube is bent it is slow. How do you know which it is do you have to take the bed off, or is there some easy way to access the vent tube. It takes forever to fill my tank, and the front tank doesn't even have a filler neck or something like that because the gas just runs out under the bed.

Once you've dropped a few tanks, it doesn't seem as hard as everyone makes it out to be. Granted, the newer the vehicle, the more lines and complexity you have. I've done it on my truck, my friend's Crown Vic (twice iirc), and his 70's Dodge "Good Times Machine" van. As long as you bring a floor jack, an impact, safety glasses, and some penetrating lube under there with you, it's a breeze. If I had to choose between dropping a tank, and, say, changing the plugs on a van, I would take the tank.
