    Helpful Notes

    • Core 3-gauge set: Boost, EGT, and fuel pressure; add trans temp on automatics.
    • EGT probe: Pre-turbo reads hottest/fastest; post-turbo reads ~200–300°F lower.
    • Fuel pressure (VE): Monitor at the inlet—use a tee and keep supply within spec to protect the pump.
    • Clean installs: Use pillar/dash pods and quality tubing/adapters from ACCESSORIES.

    Frequently Asked Questions

    What gauges should every 1st-Gen Cummins have?

    At minimum: boost and EGT. Add fuel pressure (to protect the VE pump) and trans temp on automatics.

    Where should I place the EGT probe?

    Pre-turbo (exhaust manifold) gives the most responsive, highest reading; post-turbo is easier to install but will read cooler.

    How do I add a fuel pressure gauge on a VE truck?

    Use a push-lock tee at the pump inlet or filter outlet, route line to the gauge, and verify pressure is within spec at idle and under load.

    Will 94–02 gauge pods fit my 1989–1993?

    Not reliably. Use 89–93-specific pillar/dash mounts for proper fit and sightlines.

    What size analog gauges work best?

    2 1/16" (52mm) is the common size that fits most pillar and dash pods for First-Gens.
