New Fuel Tank Design

[brncofinatic]

make the sending unit accessible from the side, so when you do have problems (always) you don't have to drop the tank to access. That would be a major improvement! and agree with he rest of the guys give up a bit of capacity to give more clearance.. Can you also figure out how to get a larger auxiliary tank? that would be pretty cool also, just thinking while you are at it do the other one also. Just a thought. Thanks jerry

Is this still on track? I heard early summer.

Hey guys, I appreciate you all being patient. We are starting to see a light at the end of the tunnel with this endeavor. I am including another image of the long awaited mounting system. It is 3 position adjustable, takes all of the guess work out of it. You will have a setting for stock height, 1" body lift and 2" body lift. The bottom holes will be for a future skid plate. Prototypes of the mounting system have been ordered so we should see a tank on the Duck in a few short weeks. The tank has undergone some heavy design changes all in an effort to make manufacturing faster. The first batch of test tanks took way too long to tack into place and weld up. We had a lot of discovery from poor tolerances held by our first selected supplier and designed more internal reinforcements.This tank is heavy 14 gauge 304 Stainless Steel. It will weigh about the same as the other tanks out there but at this time we are planning on it all to be 100% Stainless, mounting brackets included.

This looks/sounds awesome - any updated eta?

No can do with the design however we did take sending unit issues into strong consideration to resolve the issue we are using a self contained unit with no moving parts. It has a float with a magnet that rises and falls. No exposed connections like a traditional sender and since it is all contained in a cylinder, no chance of wires fouling it.

Well the first one is in and is working well. This truck will start road tests next week. The second one is going in the Duck next week for street trials as soon as my engine is back together and it is running.

When can you take my money?

Soon, we will have 6 or 7 pre production units available. We made some seam changes to assist in assembly and reduce the amount of welding required as well as a few small improvements, for example I didn't like were the drain plug worked out so it will be closer to the bottom in the new version but other than that they are the same. The mounting system is very slick, I am debating of making a drill guide for the frame rails to include with each tank. It is not difficult to line up but with a drill guide it would eliminate the need to even test fit, you would be able to locate and drill the holes then start installation.

Do you have an final dimension sheet too?

I'm expecting to have that next week. We have total capacity of 21 gallons, estimated useable of 20 but I will know that for sure when I fill it at the gas pump soon.

Here is a before and after comparison of our new tank.

Looks good! Do either of the vent lines have a AN fitting on them?

Thanks,

The filler vent is barb like factory as well as the tank vent. The supply and return are -6 AN. The tank will ship raw stainless so welding on an adapter would be easy to do.

 

[englewoodcowboy]

Looks like useable capacity is 20 gallons, total capacity is 21.5. So far very pleased with the.results and I'm loving not seeing that old tank hang so low!

 

[markw]

Nice work. Looks great. Will you have it in the catalog?

Very nice and congratulations on an intelligent design. But in the end, I hope like heck that the fuel sending unit gets at least as much attention. This after experiencing a run-out-of gas situation due to vendors who ship 23 gallon tanks with senders that are not calibrated and who fail to mention that you need to do so before installation. Just sayin'.

Mars - if this one works as well as a similar unit in a competitor's tank that I installed last year, you will be very pleased with the accuracy of the unit in this tank.

The way this is designed there is no calibration required. That is all done by the mounting height. When it reads dead empty, not E you will have about 1/2 gallon of gas available. When it is on E you will have about 2.5 gallons available meaning for most about 25 miles give or take before you will be walking. The added designs into the tank prevent over filling though it can happen if someone wanted to sit there and click the fuel handle about 100 times to completely fill the expansion area and it will take about another 1.25 gallons at that point but it will back up the vent system, charcoal canister and run out on the quarter like the other designs do when you click the pump handle off once or twice. The other design is it will read a little more evenly throughout the tank instead of rapidly from 1/2 tank on. It also is more consistently accurate so at 1/2 you are about 1/2. not between 1/3 to 3/4 like the others do. The other tanks are about 70% accurate, this one is about 90%. I could have designed it to be 100% accurate but then it would reduce the volume and make for a very tough tank to assemble in manufacturing so it would still work with all of the other requirements.

I have been testing this tank now going on two weeks and it has met every one of my goals. We are making a few more tweaks to enhance fitment issues since we have installed this about 10 times now testing and checking items. We had to resort to manufacturing an insulated electrical bulkhead because the off the shelf parts, though cheaper than for us to make them, leaked too much. Now the tank is completely sealed and I am only relying on a few outsourced components, the fuel sending unit and the AN fittings. Everything else is of my design and has been tested. I am making a slight change to the mounting system to make it even easier to install for the first time and reduce the number of holes you will need to drill to two. I am waiting on quotes from metal suppliers and CNC laser cutters. I should have them by the time we return from SCW and Put In Bay in a little over 2 weeks. Once we order the materials it will take about a month to assemble the first batch. I do not know if Duffs will want the batch in it's entirety before they ship or if they will take what we get done weekly, these are things to be determined next week. We will have a pump available as well as a part number for an over the counter pump that will also work. Thanks for the continued interest.
