3D printable washer pump gasket designed for 1980–1986 Ford “Bullnose” trucks and Broncos.

This part replaces the original rubber washer pump grommet that seals the washer pump to the reservoir. It installs just like the factory piece — pressing into the washer reservoir opening with the pump inserted through the center.

This design features a slightly tighter press fit compared to many aftermarket replacements to help reduce seepage and improve long-term sealing. Developed from a real-world application on an original Bullnose washer tank.

VEHICLE FITMENT:
1980–1986 Ford F-Series trucks
1980–1986 Ford Bronco

Designed around factory-style washer reservoir and pump. Verify tank opening and pump diameter before printing if using non-original components.

RECOMMENDED MATERIAL:
Primary: 95A TPU

Acceptable alternatives:
• 90–98A TPU (95A recommended for best balance of flexibility and retention)

PLA, PETG, ASA, or rigid materials are NOT recommended due to lack of flexibility and sealing performance.

PRINT NOTES:
• Orientation: Print upright as modeled (flange flat on build plate)
• Supports: Not required
• Infill: 100% recommended for maximum sealing integrity
• Walls / perimeters: 3–4 perimeters minimum
• Other notes: Slow print speeds recommended for TPU to ensure clean layer bonding

HARDWARE / ASSEMBLY:
None

INSTALL NOTES:
Press gasket fully onto washer pump and install in reservoir.  Fit will be tight.
Lubricating lightly with water or washer fluid can help with installation.
Pump should fit snugly through center bore. Do not force excessively — verify correct pump size if fitment is extreme.

DISCLAIMERS:
• Designed and tested on my own vehicle.
• Measure and verify fitment before final installation.
• Automotive environments involve heat, vibration, and UV exposure.
• Print settings and material quality can affect final fit and performance.
