They are nozzles only, Bosch 100 hp. Do not have any crossover tubes. I have had great success using used crossover tubes with new o-rings and installed and torqued according to specifications, never had a failure yet. Are you interested in the nozzles? I originally bought them from Scheid Diesel in Terre Haute, IN.
