I have searched for higher capacity fuel tanks for the OBS. The rear tank is available from several sources. What about a front tank? I saw one write up about a tank that was installed, but hung down lower than the stock tank. Will that be my only option if I want a higher capacity front tank?


I have a fuel leak that is draining into the front skid plate. I can't figure out where the leak is coming from. Also, whenever I have the front tank selected, it acts as if it is running out of fuel and will die. I am assuming the two problems are related.


I am thinking about removing the bed and replacing the rear tank with one of the 38 gallons ones. I would like to find a larger tank for the front, too.

I haven't done this mod but I did the 38 gallon rear tank, I love it!!

 

This is maybe more work than I anticipated. I did find a 45 gallon replacement rear tank for our trucks by following links from your post though.

 

The bronco tank (32 gallons) will also work for the rear.

 

An interesting thought I think for anyone wanting to replace rear tank for larger. The rear tanks stock typically dont take fuel very well. Is it still an issue with the bigger tanks? Or are you guys running the filler neck or breather different?

 

Most run a modified breather

 

I ran, as Nick says, a modified breather for my 38 gallon tank and it works great. On my stock front tank I did the same but for some reason it doesn't fill as fast. Anything is better then the stock filler necks!

 

Is there any downside to having a high capacity fuel opening like you find on a big truck? I guess you wouldn't gain much by using the little truck pumps, as the pumps only pump so fast, but if you went to the big truck pumps it sure would be nice to fill your tanks quickly and it would help if you had to use a can to fill your tank.

 

I can't see any downsides but I still try to avoid the big nozzles. I can use them but they still pump to fast.

 

I was assuming my tanks were the higher capacity tanks. I have had to fill my big truck tank with the little truck pumps, I get frustrated with how slow they are. When these are the only pumps available and I am very, very low on diesel, I have no choice but to use them. I only fuel about 50 gallons before I get impatient and take off looking for a real truck stop. Fuel is usually cheaper at the local fuel stations and much more expensive at truck stops.

 

Yes it does, but it's much deeper and you can't hang the spare tire back in place.
The 38 gallon tank is a tight fit and not as deep and still allows the spare to be hung, with some modifications to the straps of course.

Skip the 33 gallon Bronco tank and just do the 38 gallon tank, it's a win-win across the board.

 

What Jim said awesome mod, the 38 gallon tank works great.

I'm in the process of doing the F26E swap myself (38 gallon). Tank is primed and painted, old tank is out. I'm guessing the hard part is putting the new tank in because so far the hardest part has been the dang spare tire carrier that I'm ready to just cut into postage stamp size pieces, or the return line which took some tugging. I ordered my tank from amazon for $100 shipped to my door, no kidding. And I was about to spend $500-600 on an L shaped transfer tank. Can someone link to the tank modification? I'd like to get those done while I have it out. I hear removing the inner sleeve on the fill pipe and something about a 5/8 or 3/4 breather but im not sure how that's being done.

 

Ok I spoke to soon... Just busted the sending unit into about a million pieces (ok so just the part that reads the fuel level) is there a direct replacement for one that works in the F26E tank? So I don't have to modify it? Sorry to thread jack

 

What I did was pull out the stock roll over breather drill out the center then JB welded in a street 90 degree elbow (brass) then ran a hose from that to the filler neck where I JB welded another one into the steel elbow as I recall. With stock filler neck off I knocked out the internal reducer using a hole saw and vice grips and yanked the large breather hose off inside the filler hose and tossed it.

For the fuel gauge I took off the existing wire arm (that's in tank) and copied it with a length of fat coat hanger wire was perfect diameter match. Added think it was 7" also extended the pick up and return lines with SS tube and compression fittings. As I recall I think I left off the pick up cone/screen too as it looked like a gimmick.

Lengthened the tire carrier rod on passenger side with threaded ready rod. Took an old chain tire hoist from a Toyota and bolted it on the other end of the tire rack bar. So the chain hoist mechanism is on the tire rack not truck frame. Ran the hoist chain up to frame, took a socket and pinned a small Rod though it such that I use it for the crank with a ratchet or 1/2" drive cordless impact wrench... Works awesome.

Think I have a stock spare under the red truck so 235 and have never stuffed it. Mind you I do have a mild lift and run air bags to keep it level.
