I got tired of filling up my 26 gallon tank on my D-max and started doing some research on larger tanks. Obviously, GM didn't offer anything and didn't find anything until about a month ago. Titan Tanks makes larger tanks for all Diesels 99+. I'm having a 52 gallon installed today! Fewer runs to station, but its going to hurt when I do :cry: But at least it will help save some labor in the long run, I'll be able to fill up in the evenings or weekends and not have to worry about stopping in the middle of the day. Thought you guys might like the concept.

If I find a good duramax and get it, this info will be really helpful. But for now I've got my GM 6.5 diesel and it already has a 40 gallon tank.

I hated having a little 26 gallon tank in my 2500HD with Duramax. With the lift and some towing I was only getting 300-350 miles a tank. My 99 F250 had a 38 gallon tank and would do about 600 miles with the 7.3.

That's odd that they didn't put a bigger tank on the Duramax, especially with the fact of people hauling long distance with them.

They only put the smaller tanks on the short bed trucks. My truck has a 34 gallon tank.

I used to have a long bed and mine also had a 34 gallon tank. It was pretty nice. But it was a gasser and I needed a Diesel, so that's where this truck came in...I just couldn't find a nice used one with a long bed.

So, I just got back from the shop and I "topped" off my new 52 gallon tank and it took 36 gallons! haha At least now I don't have to worry about it on long trips or even around town. What's amazing is that the tank has plenty of room and didn't require any modifications. GM should do this at the factory

I might have to think about getting that mod done. I am looking at an 06 Crew cab dmax right now. My stakebody truck has 2 tanks. I can go about 200 miles on the front tank. It takes 35, which this is the first time i actually filled both up, so i am hoping to see 300 or more out of this fuel run.

My 07 dmax came with a 2- 30 gallon tanks. It was a cab and chassis truck though.

It surprises me that GM has plenty of room to put two 30 gallon tanks on a chassis cab which will get some kind of bed but the regular trucks with beds are limited to a 26 gallon for 6.5' or the 34 gallon for the 8'.

We have an 02 Excursion with a 7.3L and it has a 44 gallon tank. Just wish the manufacturers would put at least 50 gallon tanks on the trucks from the factory so people could use the trucks for the long hauls like they're made for.

I wish my 6.0L came with larger than a 26 gallon tank, I was just thinking that this afternoon. my dad's truck with the 4.8L 1500 and has the 36 gallon tank because it's a long bed. but my bigger, heavier and less fuel efficient truck has a smaller tank. I would love a 45 gallon tank, yes a full 45 gallon tank weighs 306 lbs, where as a 26 gallon tank weighs about 208 lbs, but I think a heavy duty truck could handle it.

So...what did the 50 gallon tank cost you ?

Installed it was 1358.00 OTD. Not too bad considering how much time I spend at fuel stations with workers. I average around 4000 miles a month, so the fewer stops I have to make, the less hours I have to pay my guys for just fueling up the truck, the quicker it gets paid for. Plus I can shop around a little bit more and not have to worry about getting 10mpg when pulling the Bobcat 853.

I found a company that makes gasoline and diesel tanks, both in larger OEM replacement and aux bed mounted ones. I'm going to give a call to my closest installer for them and ask a few questions. the company is www.transferflow.com

I no longer have a sissy tank. And its been great. Driven over 100 miles and the needle hasn't moved yet! Got lots to do this weekend, so we'll see how long 52 gallons lasts.

I have a ford dump as well.

That's great, how's the overall fit in the truck? Did they have to do any major modifying to fit the bigger tank?

I had a friend with an aux. fuel tank/tool box but he had to flip a switch when the truck was empty to the other tank. I believe he had a total of 70 gal. combined tanks.

The best part was that there was no modifications needed. Just drop the factory tank and replace with the new. Fits like a glove. Just longer the old one, keeps me from putting duels on the D-Max but I really didn't need that anyways.

I'll try and get some pics of it this weekend as long as the rain holds off.
