2 Most Common Ford F250 Fuel Tank Vent Problems
The fuel tank valve might have a clog and needs the block to be free, or the vent has a crack or it’s basically broken and needs replacement basically.
Go For an Initial Checking
No matter if it’s a ford f250 steering box problem or tank vent issue or literally anything causing trouble, initial checking will help in identifying things better.
A dual-hose setup is what the filler tube usually comes with. Unless something happened and that’s why the thing is a mess. Basically, this means there will be a hose inside the hose. The one that stays inside would let fuel flow or go in. And then the outside hose allows venting. Just next to the hole, a tiny another hole resides. And it makes sure the fumes can come out after putting gas.
Keep In Mind – You must avoid smoking any lighters, fireworks, or open flames to be around it. There are a few power tools that may create sparks. Never use those here. Also, you must work in an area with proper ventilation when handling these. Blowing yourself up should never be a case, and you ensure that by taking proper safety measurements.
Was the tank recently out? If so then consider checking if the filler tube was taken out and you just forgot to put it back. If yes, this could cause a certain f250 fuel tank vent issue, put it back immediately.
You also want to check the filler tube if there’s any problem noticeable. To check, let the tank go down and use a jack to have it rested on top. You want to disconnect the filler tube next and give it a check. No kinking or twisting is recommended.
It Could Be a Clog In The Fuel Tank Vent
This could be the first thing that happens when your fuel tank vent is facing a problem. Usually, it happens due to fuel trapping in the tank line. This causes pressure building. Or vacuum to purge the vent by creating sufficient pressure.
You may notice gas or a weird smell coming out from the vent line. And this pressure build-up is definitely no good for the tank. In fact, it can cause some serious levels of damage if action is not taken properly.
How do you take that necessary action? Well, first make sure the vent and filler cap are maintaining proper proximity. Then notice if there’s a screen on the vent. It might have a clog. You can use CRC 56 to spray on the clogged area in the vent.
And then use an old toothbrush or something similar that allows applying less pressure but still enough to scrub. Use the tool for clearing the clog and things go back to how it was!
To check the air vent line blockage, you can use a compressor line and extend it inside. Give an air shot. Can you hear a gurgling sound? If yes then the air was able to enter the tank, so there should be no blockage. However, if there’s no sound, it’s an indication of blockage and needs further checking.
The Tank Vent Could Be Broken or Damaged
If that’s the case, you will need to replace the tank. The replacement method should be there in the manual. Even If you don’t understand the instructions, it’s still useful to read. Because there could be some instruction or warning that specifically the manufacturer mentioned if ignored might cause further trouble. So read it beforehand.
Here are the steps to follow-
- You want all the fuel out from the tank so that it’s completely light. And this will make handling the tank much easier. Make sure the battery is disconnected completely. Never keep it on, sometimes people do so for saving radio presets, but please you don’t!
- Also working under the truck will make dirt literally pour on you. So, safety goggles are a must. Get the spare tire and mounting bar out. Have the jack on position and let it slightly push against the tank bottom. Get the straps from tanks out as well. You should have it halfway lowered to the floor. Next, you need to handle the tank top.
- This can feel awkward, but you should still not try lowering the tank more than halfway. Otherwise, there’s a chance of having the tank dangling with fuel and lines for the pump.
- Have all the electrical lines disconnected from the fuel pump. Use pulling tool for fuel line and WD-40 can for connectors. There’s a specialized compression tool for lines of Ford that you can use.
- Make sure you spray the WD-40 on connectors of the fuel line, not the electrical ones of course. And then use the tool for removing the fuel lines. This may feel like something you can skip. But usually, that causes later spending a couple of extra hours fighting with gummed-up connectors using a wrench.
- Have the tank on the floor very gently. Wheel it from the truck beneath. Get the fuel pump out, but don’t use any hammer to slam the part, there are specific tools for that.
- Then place the pump inside the new tank. Check the mesh screen filter also, and if that needs replacement, get it done using the chance. You can then reverse this removal process and basically have everything back to place.
For Your Information – In some cases, if the truck is too old, then having the pump replaced will also be a great idea. Quite surely after a few days, the worn-out part will become unusable and you’ll need to do all of these again. There are fuel tank kits available that also include pumps. Go for those to avoid the additional hassle. The cost will be slightly higher, but still, it’s going to save you time and effort.
