7.3 Powerstroke Funnel System

7.3 Powerstroke Oil Funnel System (OBS)

This is a modular oil funnel system designed specifically for the 7.3L Powerstroke, with a focus on the taller oil fill neck used on OBS (1994.5–1997) trucks.

More models for obs fords and superduties will be available on https://vmtsol.no/vehicle-electronics soon aswell as here 

Current Version (V1)

V1 is fully functional and gets the job done, but it has one major limitation: it does not have a vent, so filling can be slower than I'd like. The STEP file is included if you'd like to remix or improve the design yourself.

Improved version – V2

The next version will include several improvements:

• Integrated vent for faster, smoother filling.

• Quick screw-on lid to keep dirt out while filling.

• Storage cap for the funnel when not in use. (coming Soon)

• Improved overall usability and sealing.

Planned Accessories

This is intended to become a complete oil service system. Currently in development are:

• Funnel storage holder with an integrated drain so residual oil can drip back into a container instead of onto the shelf.

• Adapter for the Biltema funnel, allowing you to use an inexpensive off-the-shelf funnel instead of printing the entire funnel body. This reduces print time and material usage.

• Ball valve attachment so you can stop the oil flow if you pour too much, allowing you to pour the excess back into the oil jug without making a mess.

• Oil filter pre-fill holder. Anyone who's pre-filled a 7.3 filter knows the cardboard box is often wet, crushed, or missing. This holder will securely support the filter while filling, making the process cleaner and easier.

Remixing & Commercial Use

The V1 STEP file is included so you're welcome to create your own remixes or improvements.

If you'd like to use this design in a commercial product, sell printed parts, or incorporate it into another commercial application, please contact me first.

Feedback, suggestions, and remixes are always welcome.
