John Deere (RDO Equipment) Billings, MT
 

For those that don't know, they got a common rail injector test bench. $25 per injector, all 6 takes about 2 hours. Also, $2400 installed on 6 new Bosch injectors. So, if you live close by and are having issues, give em a shout and see what they can do for ya.

BTW, they are located right across from Cummins-Rocky Mountain, 5121 Midland Road.
