Helpful Notes

• Injector & washer sizing: Early trucks use specific sealing washers; verify year and injector style before ordering.
• Supply side health: A quality lift pump helps protect the VE pump; follow manufacturer pressure specs and monitor with a gauge.
• Return hardware: Replace aged banjo bolts, washers, and return lines during injector service to prevent seepage.
• Fuel pickup: Sumps/draw straws improve high-flow plumbing; confirm tank compatibility before drilling.
• Tuning parts: Fuel pins & governor springs can broaden the powerband; pair with appropriate injectors and EGT monitoring.

Frequently Asked Questions

Do I need a lift pump upgrade on a stock VE truck?

It’s recommended. Stable supply pressure protects the VE pump and improves hot-start and throttle response. Choose 100–165 GPH based on power goals.

Fuel pin & 3200 RPM spring — what’s the benefit?

These popular VE upgrades add usable RPM and mid-range torque. They’re a great match with mild injector upgrades and towing tunes.

How do I pick injectors for towing vs. performance?

For towing, choose modest nozzle sizes for clean EGTs; for street/comp builds, larger nozzles can work with added airflow and monitoring.

Will a sump/draw straw help my setup?

Yes. They reduce restriction and aeration on high-flow systems. Verify tank style and plan routing before installation.

What should I replace during injector service?

New sealing washers, return line hardware (banjos, tees), and brittle hoses. Inspect feed/return fittings and upgrade to AN where needed.
