Extended range fuel tanks - who has one?

I'm looking into replacement fuel tanks. I'd like to hear from folks who have replaced the existing tank with a larger replacement. Since I haul a TC, can't use a bed tank like I did when I had a 5'er. Also don't want a spare tire replacement tank...I like having a spare.

Stock tank is 37 gallons. Fully loaded, depending on where I go, I get 10-11mpg. Usually, it's my arse saying it's time to stop and take a fuel break before my gauge says to. But sometimes, it would be nice to have a little extra range.

I've found three so far for my truck, these are the best prices I could find--.
-Titan 67 gallon, ABS plastic, $1409 free shpg
-Aerotanks Aluminized Steel, 60 gallon, $980 + $170shpg
-TransferFlow Aluminized Steel, 57 gallon $1185 free shpg

The Titan appears to be the most popular, but that doesn't mean it's the best.

Any thoughts?

Fueling takes time. Time is money. Not even calculating the fuel you need to burn to make unnecessary stops.
Sure when you travel in the state with cities 200 miles apart, you don't want to get stuck, or pay arm at those desert stations, but with diesel, giving me >300 miles with camper, or 500 miles empty, the night before trip I go on gas buddy and I find the cheapest fuel on the route day before fill up.
That quite often can save me $20 alone.

Fueling with gauge showing 1/4 is waste of available resources (unless you see a sign like above).


Care to elaborate on that? What resources are wasted by me only adding 16 gallons vs say 22 by driving awhile with the low fuel light lit? Do you think you somehow use more fuel by filling up twice at half a tank vs once with an empty tank? In my case, back east, I'll go until the low fuel light comes on. West of Illinois, I hit the next station at 1/4 tank because I don't know how far it will be until the next station after that and I have no desire to damage my injectors by finding out where I break suction and start drawing air. Now THAT is a waste of resources.

I hate spending time at gas stations and test most of my vehicles how far they can go on reserve.
Almost any vehicle will make at least 50 miles with reserve light on on highway.
Maybe 30 in the city.
Still far cry to my 1980 VW diesel that would drive 150 miles with gauge showing 0 😉
Carrying small can with extra fuel makes good "mental reserve" that works well even when you don't use it.

I have the 50 gallon Titan installed on my F350 and wouldn't have the truck without it. The factory 25 gallon tank was a joke, as I'd be searching for fuel every 200 miles towing. This new tank lets me tow at least 400 miles before even thinking about fuel.

The main reason I bought it is for convenience; filling up once or twice a month is much better than stopping at the gas station once a week. I also take the truck out to some pretty desolate areas with no services for 100+ miles.

My trek on White Rim last May was over 100 miles on dirt roads with civilization and a fuel station another 35 miles after you get back on pavement. Averaging about 10 mpg on that trail meant I'd be below a half tank on the stock tank before I even got back to pavement without accounting for any of the side trips we took the three nights we were out there. Then comes the issue of having to turn around and backtrack the whole trail if the road gets washed out or there's a landslide, which happens a lot more frequently than you think.

Exactly! Depending on where you live, fuel even along paved roads can be scarce. If you're going to play in my area in Nevada for a few days you'd better have plenty of fuel.......

I've thought that the Spare Tire Auxiliary Fuels System (STAFS) looked attractive. By moving the spare the the front rack, you can put 30 Gal in its place. There are some real install challenges through like where to put the new second filler cap?

To the OP, I'd go with the Titan. Install isn't that difficult to do yourself; just make sure to run your stock tank as low as you feel comfortable before dropping it. I was able to swap mine out in my garage without even lifting the truck off the ground.

Only advice I have is to follow their torquing procedure for the sending unit exactly. I thought I had, but I ended up with a leak out the top at my first fill up. I had to burn through 50 gallons of fuel to drop it again and replace the seal. This time I not only followed their instructions, I left the tank out overnight and checked the torque every few hours until I didn't get any more movement on the nuts. The rep at Titan also had me up the torque about 10 ft-lbs over what's published in their instructions. No leaks since, and it's been a full year and 15K miles over some pretty rough terrain.

Honestly who cares why you want it? Its your truck! Seems people are more concerned with why you want it!

Anyway, looking forward to the answers as I have been thinking of the same thing.

Your money but a 370 mile range isn't limiting in my view.


It's not just the added range that makes a bigger tank advantageous. It also gives you the opportunity to be more selective about where you buy your fuel, and bypass a high-cost area entirely. While my current truck doesn't have an after-market fuel tank, a previous truck did and I loved it. I carried a total of 65 gallons between two tanks. Did I always use the full range it gave me? No. But as I said, it's not just about range. It was there if I needed it, which I did a few times.

I would go for the biggest, which would be the 67 gallon Titan. I also like the fact that it's plastic. As long as it's adequately protected, plastic would be superior IMHO.

:):)
I agree with Lwiddis. For me it is like spending $1000 to increase your MPG by 1 mpg. I cannot imagine breaking even in your lifetime, much less your trucks lifetime. To spend that kind of money cause you can, okay. To spend that money for bragging rights, okay. But if you do note frequently drive cross country, I can't see any advantage. How much will it cost to haul the extra fuel?

Guys... Sorry, I should explained WHY I want a bigger tank. It has nothing to do with picking and choosing the cheapest fuel.

I'm 54 feet long from bow to stern. I can't fit in your mom and pop convince store fuel ups. And I NEVER run below 1/4 tank unless I know for fact a fuel station I can fit in is just up ahead....so to the comment of "370 miles is plenty". I for one do not wait until mile 369 to then look for fuel. So "370 mile range" comment is entirely irrelevant.

So - this is about range and "fit into the gas station" anxiety. In my case, a 57-67 gallon tank would allow me to more easily space out the spots I can fit in.

So back to the question - anyone have one, and what are the opinions of the tank you have?

Lol, then why aren't semis regulated to 60-70 gal tanks?
Ford finally offers a 48 gal tank, real selling feature. Lame comment.......

I put a storage box on the front of my trailer when I went to Alaska to carry 2 5gal cans of diesel. Had only a 26 gal tank in my short bed. Only needed the extra fuel one time in the Yukon.

But more is almost always better.

I totally agree with those who cautioned the extra weight of the fuel. Diesel weighs 7.1 lbs per gallon, 30 extra adds an additional 213 lbs to your cargo weight. I'm not too out of line to say that a LOT of folks on this forum are already over their GVWR rating already.....

OP, your sig describes to me a pretty **** heavy rig already, hope you have "weighed" (ha ha) the safety/connivence equation. I'd LOVE to carry the extra fuel, but I won't put my family or anybody else on the road at risk for connivence sake.

I filled up in California twice in last 2 days and it was
$2.49 for B20
$2.57 for diesel
With gasbuddy you can plan your fueling without paying the high prices some downtown stations want.
Couple more facts you need to consider.
1. bigger tanks don't always let you use the capacity. I had 10 gallons in 50 gal tank and run out on steep grade.
2. use what you have in factory tank. I don't hesitate to drive with "0 to empty" as I experienced there is always extra reserve and often it will go for 20 miles.
With diesel you don't really want to run dry as that damage some injector, but carrying 5 gall can gives you "mental reserve" to stretch the tank reserve.

I read your first post and knew that's why you want a bigger tank.

On a Ford, you will be able to recalibrate the fuel gage and miles to empty by changing parameters in the PCM. Also on a Ford, the tank is amidships, weight of fuel is about evenly distributed front/rear.

I agree with having the extra fuel to reduce stops - towing my sailplane trailer I am right at 60' overall length. I have to be very careful what station I pull into.
