40L Tank CAD + Pump Case 2025 Build Guide — Bundle
Why this exists
We build our tanks in stainless steel because we value our health and we love to build and develop our own equipment. That way we ensure our equipment perfectly fits our needs. As we pointed out in this article, stainless steel has its drawbacks and at some points, plastics are clearly superior and cheaper. On the other hand, health and repairability and longevity are more important!
Together with the Pump Case we have the complete system for water filtration and storage! In this bundle, you get the Build Guide for the Pump Case 2025 together with the complete CAD package for the 40L Tank for the Front Runner Rack.

Who wrote it
I'm Sebastian — mechanical engineer (Dr.-Ing.), and I built this system because I couldn't buy one that told me honestly what it removed. It's been designed, built, and field-tested on our own vehicle, not specified from a catalogue.
The reasoning behind every stage is documented in the guide, and discussed in depth on our blog WeissExplorers.com.
Who this is for
The guide describes the system we built and tested. It does not constitute a warranty of microbiological or chemical drinking water safety in any individual application. Anyone building, modifying, or operating a water treatment system does so on their own responsibility, and is required to verify the suitability of their setup for their own water source and intended use.
Builders who want to have this tank fabricated by a sheet metal shop, or adapt the design to their own vehicle. You'll need a CAD program to open the native files — the DXF and PDF work with any viewer and can go straight into production.
Licence
Single-user license. You may use, modify, and manufacture parts from these files for your own projects, commercial or private. You may not redistribute, resell, or share the files, in original or modified form.
Disclaimer
These files are provided as-is, without warranty of any kind. The design is intended for a vented, non-pressurized water tank. You are responsible for verifying the design for your application, for proper fabrication and welding, and for secure mounting on your vehicle.
