We think almost all these old M119 V8 engines need to have their fuel injectors replaced for peak performance and better fuel economy. We also believe an old fuel pressure regulator should be replaced so we are including one at no additional cost.
Product Details
These are very high-quality aftermarket fuel injectors.
These do wear out and will affect fuel economy. New easy-to-install fuel pressure regulator included.
