Diesel Aux and main tanks

[travelin2]

I have a 36 gallon gas tank and get roughly 400 miles per tank when towing . . . 500+ when not towing!

I don't think there is anywhere in the US that is more than 400 miles away from a gas station.

Not too mention that I like to stop and stretch every two hours or so . . .

My short box SD has a 26 gallon tank so they say. Pulling the BH I figure 10 mpg (I do usually end up averaging a bit more once I calculate the whole trip) so without the aux tank at 200 miles I was looking for fuel.
AND I've been out west there and been in locals where fuel stops are far enough in between that I'd have been really nervous about making it to the next one. Nevada and Montana, to name a couple. So without the aux tank I may have been sitting along the road.
Traveling to Alaska this past summer it was a MUST have!!!!
Point is for me, among other things, it's knowing I'm good to go for the day when I have a full load of 60+ gallons of diesel regardless how remote the route I take.

Thanks. that is a strong case just for adding the extra large fuel tank. I figure that would give me at least 400 miles of travel before I would start to look for fuel station or at least start thinking about it. I don't think the kids would make it that long though. so I may be stopping before that but at least I could cut my stop time down.

I have the 60 gallon tool box combo tied into the fuel fill tube. I did add a fuel filter just because. Only use the gravity method. Install was easy and does not leak. Truck has about 38 gallon tank. What it does for me is that I can fill up when I want to
not when I have to. This also allows to find the cheapest and not have to worry about getting trailer in a tight spot. I normally have to take the dogs out first. Freight and all was about $904 plus $65 for hook up kit. Really easy to do one self.

Oh we stop often enough. Just because I have fuel doesn't mean we roll along all day without stopping. We have the dog too that needs a break, there are pull offs and vistas to explore, coffee breaks, pee breaks, more pee breaks...
As I have mentioned in other posts we tend to take roads less traveled so fuel sources aren't necessarily advertised and are typically more expensive in the smaller communities we pass through.

We had a small tank in our old 2004 GMC. I think just 26 or 28 gallons. We were fueling every 200 miles. Our longer trips were usually close to 1000 miles. We had 2 scares where we came close to running out, due to issues beyond our control. Refueling always meant truck stops, which were always problematic.

Now with our 115gal Dually Depot tank, we never stop to fuel on the road with trailer in tow. We can rest-stop when and where it's convenient, fuel while in motion, and get there sooner!!

Dually Depot is in Elkhart, not sure if they ship. But it's a pump with switch in cab, that runs fuel through a filter first. Overflow flows back into aux tank. Works great!!! We got a really good deal on a used tank, with new pump, filter, fuel lines, etc and installed for $800.

This is similar to the auxiliary tank we installed. It is low enough under the tonneau cover that I'm thinking about installing a Viair compressor/tank combo above it. https://www.amazon.com/dp/B001U3RDHE/ref=cm_sw_r_awd_emNtwb4E9SJP8

I installed the gravity flow kit. Very easy. And not much to go wrong. Also added an additional inline filter.

Same one I have. Northern Tool, same price. I had free shipping. DIY in a couple of hours.

Our old Dodge Ram 1500 had a 26 gallon gas tank . . . and we typically got around 250 miles per tank.

Although on our way home from South Dakota a couple of years ago and driving straight into a strong wind we didn't even get 100 miles out of a tank.

We ran out of gas in the middle of Nowheresville, Nebraska (between Chadron and Alliance) . . .

Here is a shot of us sitting on the side of the road waiting for Good Sam's Roadside Assistance to bring us some gas:

That's why I carry at least one 5 gallon tank with me

John!!! Should have filled up at that last exit!

Well . . . we were gonna . . . but this was the day before the Sturgis Rally started, and the line was so long at the one gas station in town that we thought we'd get gas in the next town!

Turns out the next three towns had no gas stations.

We have a 2004 GMC Sierra 2500 Crew cab that we have had a Titan tank on since 2006 (after our first time towing with the truck and the truck wanted to stop at every fuel stop along the road it seemed like). We have been extremely happy with the tanks and especially the extended range that it gives us. It doubled the capacity of 26 gallons to 52 gallons. We had one issue a few years ago where the tank was pulled out and would not seal back up when it was replaced. Titan cut us a deal on the new tank even though ours was out of warranty as they said it should have sealed up.

They are expensive to get and really expensive to fill at $4 per gallon but we would do it again in a heartbeat.

I was running an rds 30 something gallon in my shortbed 350 with the solenoid. ...best dang thing for towing ever.....old bumper pull got me about 11 mpg towing. ....when main got to 1/4 I flip a switch and it fills up while driving. ....

Out here in texas and when we went north to Rushmore it was a blessing. ..at one point we got into a 40mph head wind and mileage went to 7mpg....without the aux tank we woulda been stranded

I don't know If I have had a big headwind but would towing up mountains equate to the same thing in fuel milage? I was about mid 9's when mountain towing?

 

[Bigburd]

This is what I use. A 58 gallon, polyethylene transfer tank. Self contained, just add 12 volt power source. In bed on trips, out when not. Also used for my diesel tractor. A little pricey.

Exactly!!!!
If you don't run the interstate system, it can be an adventure!!!

Headwinds are like towing uphill. Last year going west across Kansas we fought our way through a headwind from Wichita to Dodge City on US 50...less than 8 mpg at 50 mph. Most of the time the SD in T/H mode was shifting between 4th and 5th gear. !

Bones, I had a 34 gallon tank made and it sits on the left side of the bed. Is gravity feed and only takes up about a 1' and 1/2" of space. With the 36 gal main and 34 aux tanks, at 10 MPG I figure 700 miles before needing fuel. I leave the aux tank valve open so when its empty, the fuel gauge main tank starts to read fuel left. Been working great for 2 years.

 

[TGLBWH]

In my 2008 Silverado it too only had the 26 gallon tank. Bought a 41 gallon gravity feed tank from Pickup Specialties, http://www.pickupspecialties.com/Delta/delta_liquid_transfer_tanks.htm
Easy install and cost about $550 and worth every dollar. It is actually for sale since it won't fit under the new retrax cover on the new pickup. PM if interested

I am always ready for a break by the time I've gone 250 miles.
