Fuel Tank Collapse; this normal?


2nd question; how can a person change the oil life interval/alert in the computer; from 3k miles to 5k miles?

Respectfully

Thanks

 

Um, the fuel tank could be expanding or collapsing based on ambient temperatures. Then again, you would think that there's a valve in there somewhere to keep the pressure steady.

The Intelligent Oil Life Monitor is a bit of a black box. Basically, it understands the type of driving you're doing and how much of it. You can't tell it to aim for 5K oil change intervals. I ignore it, except when it agrees with me. I change the engine oil according to the severe duty schedule, so right at 5,000 miles.

 

Step 2: Press and hold the ‘INFO/RESET’ button on the steering wheel for two seconds and release it. The oil life monitor will be reset to 100%.

• Tip: If for any reason you need to change the percentage of your oil life, simply press and release the ‘INFO/RESET’ button again to reduce the oil life by 10% each time.

 

I wish I could see the oil life percentage - my truck does not display this information, I am able to reset the engine oil life monitor by pressing and holding the "Reset" - hold down "OK" button.

 

if thats with a full tank i would get that replaced under warranty. definitely using up some capacity

 

On the oil life; advice taken on resetting the life to 40% after the first 10% (3k mile) alert. Thx.

Made the appt with the dealer to have the tank looked-at tomorrow morning.

Fuel tank looks to be plastic...?

More to follow.

 

They are all plastic--HDPE, I think. High Density PolyEthylene possibly.

 

I'm probably jumping the gun, but I'm thinking about paying the extra money for skid plates, if the dealer is going to replace the tank.

We shall see.

 

Theres not enough info given to know if theres a problem with your tank. Has the truck sat without running for long time? Is the pic taken with the truck running or was just running? How much fuel does the gauge say is in it? Is this a gasser or a diesel?
Whats the weather/temperature been lately?

one thing we do know, your fuel cap is good

 

Normal operations; it's been that way since day 1.
Truck has @14,900 miles; @ 1 year since purchased new.

Typical Oregon weather.

Thanks

 

The tech pulled a vent failure code from the OBC; he ordered me a new valve and fuel tank.

I will wait a few months before covering the new tank with a skid plate.

The tech said a skid plate would of shrouded the collapsed tank...so I'll wait.

From past posts, it seems like if you don't have the skid plates already, the install of skid plates is not simple. It isn't a case of simply bolting on skid plates. The brackets that the skid plates attach to do not exist and have to be added first.

 

Thank you, I won't take the task lightly. I can remember having to replace 4 OEM fuel pumps on my 98K1500: req'd a tank removal or bed removal, or cutting a hole in the bed.

The tech asked me to bring this truck with as little fuel as possible....gladly.

 

prolly not worth installing an oem skid plate if you want real protection

 

If I found an alternative skid plate that was superior in protection to the OEM (thinking outside the box), that did not required drilling into the frame (coloring ouside the lines), I would do it.

I don't plan on skidding-over anything, but flying road debris can cause serious damage; that is what I would want protection from.

Chunks of tires, retreds, wire, metal, tree limbs, lumber, const. debris with nails, antlers, etc., bouncing up into a plastic fuel tank....sometimes, the debris cannot be avoided.

But drilling the frame to install anything (other than mounting a 30MM Vulcan) would be a big NO-NO.

Thanks, looking into after market.
