What is the additional cost to install a natural gas fuel system in a truck manufacturing process?

Installing a natural gas fuel system in a truck manufacturing process typically involves several components that contribute to the overall cost. These components can include the purchase of specialized tanks, fuel lines, and necessary modifications to the engine and exhaust systems to accommodate natural gas use. Additionally, safety systems and compliance with regulations can add to the expense.

The choice of $20,000 reflects a reasonable estimate of the comprehensive costs associated with this type of installation, which includes both the physical equipment and the labor necessary to integrate it properly into the truck's design. The significant investment is justified by the potential benefits of using natural gas, such as lower emissions and fuel costs, making this option attractive for both manufacturers and operators in the long run.

In contrast, the other amounts listed may underestimate or overestimate the expenses involved in transitioning to a natural gas system, which is why they wouldn't accurately represent the financial implications of such an installation.
