new Excursion aux tank

[fiveohpatrol]

Just had a custom auxiliary tank made for the Excursion, and had to share.

A couple years ago I bought this 105gal aux tank (pickup style) that I stick in the back for long hauls. As you can imagine, this takes up a ton of room.


I realized that on the majority of the trips that I need extra fuel, I have only needed about 30-35gal or less, so I decided to have a custom tank made that takes up some almost unusable space.

So, I measured the area behind the second row and came up with a tank design that fits down in the foot well for the unused 3rd row. The design ended up yielding right at 35gal.

A racing friend recommended this place to have it made: http://dadscustomintercoolertank.com/
This guy does amazing work. I have a few friends with air-to-water intercooler tanks that he has made, so I've seen the quality first hand and had no worries about the outcome.

Here's how it turned out:


The welds are purty:


I had him put 2 3/4" NPT bungs at the bottom. I'll run one of these to a switching valve and then to the underbelly tank, that way I can re-fill the main tank while cruising down the road. No more slow pumping at rest stops!

One of the top fittings is for a vent, and the other is a backup pickup tube, just in case the switching valve system doesn't pan out for some reason. Fittings are cheap and easy to do when it's being made, so I didn't want to have to do it twice.

It fits the area perfectly, and still leaves me with the full cargo area for other junk. I could put the 105gal tank in too if I really needed to. Good thing I have air bags on the rear!

Between this new one and the main tank, I should have about a 1100 mile range on WVO, and about 700 while pulling the racecar trailer. Still not quite the range of skyskijason's 200gal tank, but much better than what I had

Nice to have that extra range, looks great!

That guy knows how to stack some dimes! Nice work.

checked out his website nice stuff. I have wanted a WI injection tank to mount on the frame rail on the passenger side. I was thinking of ached 40 6" PVC but the aluminum would be so much nicer with welded in JIC fittings and brackets. I got to call this guy. Thanks for the post.

I THINK they dont use aluminum tamks for WI because methanol corrodes it.
I could be wrong.
If you only ran water I guess it wouldnt matter anyways.
If you lived somewhere cold, straight water might freeze on you tho...

That's a very creative idea, I like it! I need to contact him about building me one to replace my steel one

Awesome tank man! Those welds are incredible!!

Sorry... I forgot to mention - That is a very nice tank.

Extended range on WVO is always a good thing.
