Fuel tank/toolbox combo

I honestly do not know. It takes a while (hours). The aux fuel line is pretty small and I also wonder if there is some restriction due to the 1-way valve where it meets the OEM fuel filler hose.

I decided to top off the OEM tank once at home so I opened the aux tank on/off valve and checked the dash gage after an hour - the fuel gage had hardly moved.

But the overnight method works great. I have almost 38 gallons in the stock tank and I get 11 1/2 - 12 mpg so that's about 450 miles towing on the OEM tank. And I don't really intend to go that far in one day. I'm now retired and officially not-in-a-hurry.

I'm in favor of the gravity method; it's nice and simple, no electricity needed. And the RDS tanks do have a simple gage built in that appears to be pretty accurate so you can tell how much is left after refilling.

I don't want this to sound like I'm advertising for RDS. I have no connection to them. Their prices are good and the tank as well as the attachment kit work exactly like they're supposed to. I'm real happy with mine.

One last thing - I read somewhere that they will build a tank to your dimensions but I have not verified that. The advantage that I see would be that you could have it built to fit under a specific tonneau cover.

how long does it actually take to transfer the fuel by gravity?

Dave H M - You may be right, I'm no lawyer. I'm originally from Iowa and my farmer friends put diesel in those John Deeres.

Here's what the RDS site has to say about the gasoline question - http://www.rdsaluminum.com/auto-intro.html

Hey, I'm not trying to start an argument. Having been around gas and diesel trucks and gas and diesel boats, I just know you have to be a lot more careful handling gas. All it takes is one spark for gas.

aruba5er - I had also heard about the computer problem so I travel with the valve closed. I open it when I stop for the night and flip it closed before I leave in the morning. The computer thinks I just pulled into a Pilot's and fueled up so it doesn't complain.

I really like the security of having the extra fuel on board. I bought an RDS from northern tool. 2 issues: first, the computer doesn"t like the fact that you are putting all those miles on and not using any fuel so once in a while it flashes CHECK ENGINE. I talked to a guy at RDS and found out that I can open the valve, get a bunch of fuel and then close the valve. let it drain some fuel off and then open it again. no big deal, do it between potty breaks. Secondly I have a tonneau cover and the lid of the tool box would not raise up high enough. I cut the tool box lid in half and installed a full length piano hinge. Problem solved.Would not be without the box/tank.

I bought ours from Transfer Flow. It's a compo 50 gal. tank with the upper top a tool box. sets flush to the top of the bed. has a auto, top of dash mount moniter system and transfers fuel into the OME tank as the fuel is used. I have had this system for 4 years and just love it. Took me about 3 hours to install. Go to transfer flow on the web. they have quit a few options.

X2...Mine is a 35 gal w/tool box. Love it

ROYB - The RDS unit I have has a cover that is full-width and completely covers the filler cap and vent tube. I wanted everything out of the elements.

Also you might want to read up on the gasoline vs. diesel rules as regards to these tanks - I believe there are some differences. For instance, I just read on the Northern Tools site, that they can be used to transport gasoline, but not to transfer gasoline to another vehicle. I'm sure it's because it's much easier to have an accidental BOOM ! using gas as opposed to diesel.

Sounds like the Northern Tool Lawyer is a city slicker.

How do the farmers get gas to the field. Answer, In a tank in the bed of their pick up.

I don't know. :h

i just installed a 72747 rds tank. its great not worrying about fuel. the gravity feed freaked me out at first. but i haven't had any issues. i have had it for 2 months now.

I have a bed cover so I did not want a tool box with it-its about 13" high. Bought my 60 gal from Amazon through Northern tool made by RDS. Shipping cost are cheaper than direct from Northern. I now have 96 gal of fuel on board and getting ready to roll out this week for vacation. No fuel stops for me.

Guess you all talking about one of these....


Interesting - Might be great for the 2KW Generator I have sitting not too far from where this would be in the back of my truck...

Mine would have to be low enough to sit under my FOLD-A-COVER folding bed cover...

Recently I have been using my Oklahoma Credit Card to suck gas out of my truck to keep the generator running when camping off the power grid hehe..... One guy told me to just get one of those Honda gas cap ports and run a small hose down the truck gas fill cap - Havent tried that yet. Yet another PLAN B thing I reckon...
