PDom - I used to follow you over on the Excursion forum (I had a 2004 Limited V-10) that I LOVED. You put together some great rides - I'm a big fan!! Wish I had a fraction of your talent.

 

A lot of the 7.3 superduty guys did this (remove spare tire, fit excursion fuel tank in its place). If you search in that section, I am sure you can find a write up on it (or ask). All you need is to have the fuel sender from the Ex tank still in it, and plumb the fuel lines/sender for both tanks with what is called a Pollak valve (google it). Cab Chassis trucks with 2 tanks use this valve, as did Pre 97 trucks with twin tanks.

Setup correctly this will enable you to use a toggle switch in the cab, and switch between the 2 tanks. The fuel gauge in the cluster will read the level of whatever tank is being drawn from.

I plan on doing a similar setup, but I hope to use 2x35 gallon midship tanks (from the shortbed gasser trucks) on both sides of the rear driveshaft, as I want to retain the spare tire under the bed. My truck will be deleted, so no need for the urea tank on the drivers side (and I hope to use the urea fillup point for the 2nd tank filler neck), and I will route the non DPF exhaust outboard of the frame rails at the transfer case and dump it after the cabin but before the rear tire.



More on topic for the OP, its looking good!

 

Got the frame cut on The EX today. Rolled the front half off with the motor and trans still in the frame. Rolled the back axle off and outside to. Put the 2012 on the frame rack and gutted the interior. Monday call for the windshield to be cut out and started taking everything off the underside off the truck.

 

Good job so far. More questions if you don't mind them.

I see that you've cut off the frontal section of the Excursion frame with the V10 gas engine drivetrain, along with its pre'05 suspension setup. Also removed the rear axle from the Excursion frame. I will assume the intent is to cut the '12 F-250 at the exact same point as you did with the Excursion's, so as to weld the Excursion specific rear section of the frame to it, thus maintaining the correct Excursion specific wheelbase, am I correct in that assumption? Removal of the old Excursion's rear axle will achieve transplanting the updated rear axle along with ensuring both the front and rear axles also have the same 3.31 or 3.55 axle ratio which I believe is what is the standard fare for a '11 and up F-250/350. Speaking of rear axles, does the '12 have ELSD? If so, that may be a bit of work to wire in. Also, do you plan on cleaning up and treating the rear section of the Excursion frame so as to closely match the condition of the frontal section of the '12 frame before you weld the two togther?

I see that you will have a surplus of parts left over from this build, consisting of a complete 6-3/4' pickup box with tailgate, rear section of the '12 pickup frame, rear axle assembly from the '05 Excursion (which I will assume to have a 3.73 ratio), along with a complete V10 gas engine, transmission, transfer case and front suspension and front axle assembly. Do you plan on selling all those parts to re-coup on some of the costs of this "project"? Lastly, how does it feel, taking apart a perfectly good, nearly new and beautiful '12 F-250?

SORRY FOR ALL THE QUESTIONS.

 

Impressive!

 

If it was me it would feel great to cut all that up and make something that I WANTED. I have a funny feeling he really isnt worried about recouping any of the money with the parts. He will with the end result. imo. Great work. Keep the pics coming.

 

Gut-wrenching to see that 2012 go to pieces like that. Much more painful than seeing those blasted SPCA commercials on TV.

 

My wife has always wanted the longer version of her Expedition, and given the poor fuel economy, a diesel Excursion would be the logical choice. It's a shame they discontinued the Excursion, as the diesel made it a good choice with good fuel economy. Good on you for making what should be on the dealer's lot...

 

You, and a lot of people feel this way it seems. Unfortunately, due to RELATIVELY slow sales, and I surmise pressure by either the Federal Government as well as tree hugger activists to discontinue production of perceived large wasteful vehicles are what contributed to its demise.

A little off topic, but how many of you think the Cadillac Escalade Hybrid should by considered an oxy-moron?

 

And yet the Suburban lives on...

 

The 12 will be cut at the same point on the frame and all the drive from the 12 will be transplanted onto the excursion. All the electrical will be used from the 12. So there will be know splicing of wires except the ones coming from the rear of the Excursion body. ( heat/air, rear wiper, rear defrost, quarter vent windows, 12v outlets, interior lights)

I will be selling the left over parts in the near future.

Cutting this truck apart is kind of hard for me because I am use to rebuild wreck vehicles or like that last build buying one wrecked and making an Ex out of it. But it is what it is the work has to get done. Makes the build process go a hell of a lot faster.

 

Looking good so far! So why did you sell your 6.4 diesel Excursion if you don't mind me asking?

 

Never planned on keeping it.

 

Just out of curiosity, since you're doing so much work already, why add/keep the emissions equipment at all if you "don't have to?"

 

It's a cost thing and this one is not mine. He will be doing a delete possible before the truck leaves the shop. It's also nice to be able to put the truck back to stock in case it gets sold or it needs emission testing.
