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.
When asking for a well drilling cost or estimate you will be given a standard price, one for drilling and one for the cost of steel casing. Currently on Vancouver Island, British Columbia.... the cost of drilling a well will roughly be $20.00 per foot for drilling and $20.00 per foot for casing. new water well drilling rig can be worth upwards to a million dollars fully equipped, there's additional equipment involved too, the cost of operating water well drilling equipment is high. Wages will be paid to normally one journeyman water well driller per rig.
