WATERMAN RACING NOSTALGIA BERTHA MECHANICAL FUEL PUMP

Waterman Racing Nostalgia Bertha Fuel Pump

Part Number: WRC-21414
Configuration: Reverse Rotation | 4-Bolt Flange Mount | 3/8" Hex Drive | Aluminum Center | .700" Gear

Overview

The Waterman Racing Nostalgia Bertha is a mechanically-driven, spur-gear fuel pump built for high-pressure, high-volume drag racing and injected/blown engine applications. It's designed as a modern, durable replacement for legacy Enderle-style mechanical injection pumps, offering superior gear construction for long service life even under sustained high RPM and fuel pressure.

Key Specifications

• Flow rate: ~16.25 GPM @ 4,000 pump RPM @ 100 PSI (based on the .700" gear set)
• Gear type: Precision spur gear construction — smoother, more consistent flow and longer wear life than standard gerotor-style pumps
• Rotation: Reverse rotation (confirm your drive/cam direction before install — this is not interchangeable with standard rotation pumps)
• Drive: 3/8" hex shaft drive
• Mount: 4-bolt flange mounting
• Center housing: Aluminum (lighter than the steel-center version, common for weight-conscious drag builds)
• Body construction: Machined aluminum, anodized finish
• Made in: USA

Typical Applications

• Mechanical fuel injection systems (Enderle-style hat/barrel injection)
• Drag racing, Pro Mod, nostalgia drag, and blown alcohol/nitro applications
• Can replace Enderle 990, 1100, 1200, and 1280-series pumps depending on gear size selected
