I can no longer store the spare tire for my 02 F350 under the bed, because it's too big to fit (I have a lift and oversized tires, hence a larger than stock spare). I got to thinking that another fuel tank would be a good thing to fill in that empty space. Where can I buy one?

 

IIRC, the Excursion has a fuel tank in the rear of the vehicle, between the rails.

 

OOH! That's right. And a big tank at that! This may be just the thing I need. Thanks.

 

Do a search on here for rear tank install I have seen people post about doing it but don't have the links.

One guy used a Excursion tank and wired it so that it had a pump in it that simply pumped fuel to stock tank when that tank ran low. Not sure what he did for filler tube. If there is space to run it up under the license plate like some of the older cars had that would be cool.

I have thought about doing this to I carry my spare in the bed anyway so it is easier to get at.

 

As for placement of the filler neck, I cut out and saved the filler door assy from my old bed after I replaced it. I still have yet to repaint my truck, so I had in mind welding in the original filler door behind the back right fender. Then using the stock Excursion's filler neck.
