jaz fuel cell

[gm tech]

anybody run one of those jaz fuel cells in more of a dd rig? does the filler neck run in the same location as stock?

Assuming you're talking about the under-the floor fuel cells:

You can run one in a daily driver, and route the filler neck into the sock location, however, you'll still have a penetration through your floor, and the fill tube running through the passenger compartment.(not a great idea)
No direct knowledge, but I have heard that some states outlawed fuel cells for no-road vehicles. Check your local regs.
You won't pass emissions. If you have the required check where you live, they'll fail you when they look at the gas cap on the OBD-II systems.(even if you figure out the check engine light)

Aero tanks in San Bernardino make a replacement tank around 30 gallons that uses the stock filler/vent locations, but they're kind of spendy...around $430 for EFI.
