Very nice!
The thing that worries me most is connecting fuel pipe. Is this doable on driveway?
I am in the middle of the second such installation on my T6 - as you can see I was on a driveway yesterday...
Yes, it is absolutely possible to do it on the streetside. If you drive with your both front wheels on the curb, it will be even easier.
The hardest part (but still easy) is to take off both right and left mudguards.
Fuel tank does not need to be dropped at all! (if you have a webasto water heater installed). I know many people in this thread have done it but check a few pages back for the official VW way which does not require a new line from the fuel tank.
You just need to tap into the existing line right before the dosing pump for the webasto heater. And for this even the webasto does not need to be dropped.
Here's the schematic of the fuel line (and a hint on the fuel line parts needed, in case you are making a kit yourself
):
Heater install is about 30min job including the mud guard removal.
Another 30min for the fuel line.
And several hours for the cutting work for the air vents in the body and trim.
