Do you need to change the connecting tubes to injectors when you install new injectors? One of my tubes looks damaged where do i get the tubes? Dealer? Any other source? I have a 2003 with S.O. engine.

 

cummins metro power 973-491-0100 in the bronx, just get regular shipping, u will get it next day anyway, has allways been the case for me....or u can call long island truck parts, anything cummins from them is purchased thru metro power anyway. but prices from long island truck parts r either the same or slighlty less. long island truck parts is in coram route 112. you dont need to change them everytime as long as u r careful. if u feel the need to order from someone else ive ordered from scheid diesel but shipping takes a while. just have your esn or cpl # ready, they will ask u for it. long island dodge dealers dont stock anything, and they will order it from metro power and u will pay 10x more at the dealer, i learned that lesson a long time ago. when ordering from metro to get it asap u must order first thing in the morning, they supply all the dealers on long island and ship fast.

 

Yeah it pays to have a relationship with the local Cummins dealer. I have one about 30 miles from my house and I pass by there about once a week. I just call them and get what I need then pick it up on my way past.

BTW, it is not a must to replace them when changing injectors, but if you have any doubt about if they are good or not, replace them. The pressures involved in our fuel system are nothing to play around with.
