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.
Size of Pump: 3/4 hp. The cost of well drilling far exceeded my expectations. Total cost for the well drilling and casing came just under $11000. The pump, pressure tank, etc added up to another $4000. I wish I knew before buying the land it would be so costly. At the very least, the estimates I received prior to drilling were accurate.
