Mine is a 42 gallon Suburban tank inside the bed under my fiberglass cover. it sit's right behind the cab and it was for a TBI fuel injection pump to start with. All I did was swap the pump out for the TPI motor and now for the LS motor.
You can use the foam but as stated it will start coming a part later on. The best solution is a tank made for this app.
I can't see anything wrong with the Aluminum tank as far as normal use. The steal will be a bit more stronger maybe.
The thing I don't like about aluminum is the threads are bad to strip and on SS they are bad to galling.
