Fuel System Management
Enhancing your 1991 Chevrolet Cheyenne's performance goes beyond just engine upgrades; managing the fuel system effectively is equally important.
Start by upgrading to a high-flow fuel pump, like the Walbro 255lph, which can support increased horsepower and performance modifications. Since the stock TBI fuel injectors are rated at 19#/hr at 60 psi, you might consider larger or aftermarket injectors to boost fuel delivery efficiency.
Additionally, installing an adjustable fuel pressure regulator allows you to fine-tune fuel delivery based on your modifications and performance demands. This level of customization guarantees your Cheyenne performs at its best under various conditions.
Don't overlook regular maintenance, either; replace the fuel filter and O2 sensor every 65,000-80,000 miles to prevent fuel delivery issues and maintain peak performance.
While higher octane fuel can benefit modified setups, it's crucial to remember that stock TBI engines run well on 87 octane. You may find that tuning adjustments will allow for better performance with premium fuel, but this should be part of your overall fuel system management strategy.
Keep these tips in mind to get the most out of your classic truck.
