I have a cummins p7100 4bt 130 hp engine. It is the 1839 CPL. I am wanting to see about getting new injectors for it but i dont know what to order? are these supposed to be just like the 12v ppump injectors with the 145* angle and around 265 bar pop off? Would a regular ole set of 145* 5x10s work well or do i need special injectors for the pistons in this 4bt? thanks yall
