Titan fuel tanks

[GPD270]

I am probably going to be getting one for my 2010 F350. My question for you all that have them is this. Does the gas needle act the same as you consume fuel. The Titan web site said that the MPG, miles to empty, read out would not be accurate. I will be getting a H&S minimax too and was curious if they have flash that would make it accurate. Thanks

Regarding the DTE, the closer you get to empty, the more accurate it will become, assuming it was fairly accurate to begin with. When the tank is full, it will be far from accurate. This is because you can't tell the computer that you have a tank larger then what was programmed by Ford. Once it get's down to the size originally programmed, it will start to function closer to as it does now.

Regarding the MPG, that has never really been that accurate to begin with, especially if you are running a tuned vehicle. Best to just use it as a very rough estimate and calculate by hand for exact numbers.

Regarding a flash to fix these, no, no one has written a flash that will address these issues.

If you do get another tank, before you install it, check to see how long the vent hose is within the tank. If the vent hose is anything like stock, the fuel pumps will shutoff long before you have actually filled the tank. This could be anywhere from 5-10 gallons that you would have to slowly pump before it finally get's to the filler neck. Harpoon it before you mount it.

From my understanding (from what I've read), the dash gauge should work the same. It will just go down a lot slower due the volume of fuel. As Titan says, the overhead thing won't be right for the reasons Shaun (smotrs) cited.

What size are you thinking of installing? If I had enough expendible $$, I'd definitely consider going with their largest tank. I tow a 12K 5th wheel ever now and again so that would keep me on the road longer.

Thanks for the replies. I tow a 14k 5'er so I'll go with the 67 gallon. I hate stopping every 300 miles for fuel.

X2 I want to do the same thing.

I have an 06 my dad replaced the 29 gallon with a 46 gallon tank. Im not sure how accurant the computer is but is will give you a reading. When i fill up it shows 455 miles to empty. When it drops to around 310 miles it will go right back up to 330. It will do this like 4 times or so until its satisfied and then starts it downward spiral. I love it until its time to fill it up..

Yeah, they usually don't start getting close until it get's down past the original fuel tank size. At that point it starts to get closer to actual.

Anyone see how long the vent tube was prior to installation? Curious to know if users have to perform the harpoon mod on the larger tanks or if they come with a shortened vent tube from the factory.

[Twinjracing]

Yeah need a loan to fill it up any more.

[Daxman]

Not sure about the vent tube, job was already done when i got it. It is nice driving from Pensacola to NC and still having over 1/4 of a tank left and not having to stop to get fuel.

daxman, does it fill almost all the way up or does the pump stop before it's completely full? On the stock tanks, they would fill up to about 5 gallons shy, then you had to slowly fill it up to get the last five gallons in the tank. Do you have to do the same with the titan?
