The fuel injection system is composed of the fuel inlet line, the injection rail, the electrical connector and the fuel injector. A pintle cap sits on the bottom of the injector inside the cylinder. Pintle caps can become cracked or deformed and sometimes must be replaced. Replacing the pintle cap on the fuel injector requires the dismantling of the fuel rail system to reach the part.
That estimate seems extremely high, but I'm sure that the actual costs will depend greatly on the local market situation and geology. Here in northern Maine, my well was around $9000.00 complete. This is a 275 ft. deep well drilled primarily in rock with bedrock being struck at approximately 35ft depth.
For example, two well drilling companies -- one in Pennsylvania and one that covers New Hampshire, Vermont and central Massachusetts -- state the cost for drilling a well and outfitting it with pump equipment averages between $5,000 and $7,000, at the time of publication.
