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.
I am not a mathematician, but $9000 divided by the depth, 275 ft, equals approx $33 per foot, not $100. That includes the cost of the pump, pressure tank, piping to house, wiring to and from house, all labor, and well test/water test. So the per foot cost of drilling is probably closer to $20. $100.00 per foot <br />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 kit uses air power to drive an air motor which is down the hole in the well, directly behind the drill bit. While a totally different concept than other well drilling methods, it is quite effective. Drilling your own 100-foot deep well will cost you about $1,200, not counting the cost of the well pump.
