Installing a removable table

Good evening

There is maybe 2 to 3 inches of clearance.

If I were you, I would drop the tank, install you pedestal and then install the tank back up to prevent the possibility of damaging the tank.

Bolting would be the correct way to take the weight and movement while driving.

You are welcome

Always glad to help

Hi and thanks for using 2carpros. Com

Honestly, that isn't listed in any manual, so you are only going to get estimates on the spacing. I will tell you there isn't much more than an inch. I strongly recommend removing the tank before doing this. Not only is the tank a concern, but also fuel lines and wiring.

I suggest a carriage bolt installed from the bottom up. That way there will basically be nothing that can contact the tank or its components. You don't want anything that can poke downward and puncture the tank in the event of an accident.

If you decide to remove the tank, here are the directions specific to removal and replacement. The attached pictures correlate with these directions.

Let me know if this helps. Also, make sure to disconnect the battery when doing any work on or around the fuel tank.

Take care,

I did something similar to this in the company vans I used to drive. However I made a bracket out of steel that bolted between the factory front passenger seat mounts.
If you are mounting it in the rear you could do something similar and bolt it to existing fasteners. That would eliminate and worry about damage and it would allow it to be removed easily if needed.

If you intend to bolt it to the floor you really should drop the tank as the tank is almost flat against the floor in places. That would allow it to be bolted using a through bolt and you can see where the tank sets and avoid problems.
