Most tank fittings first have a hole cut and then a big router spin welds whatever fittings you desire in place.

It is fairly cheap per fitting so do not forget to install at least a 2 inch deain as low as you can get in the tank.

Winterizing can take a LOOOOng time is the fresh water pump is needed to drain it.

Thick wall, thin wall, all plastic tanks will flex, and work harden.

The best plan is to install the tank in a reinforced box , ply is fine, if you only want to purchase one set of tanks.

While the tank is new it is a good idea to install a clean out port , the after market fuel tank units work fine.

Someday the tank will sit too long and grow "stuff" inside , nice to be able to scrub it rather than flush multiple times , and to hope its clean.
