DTech Injector Connector Tube 03-07 Dodge 5.9L CumminsThe connector tubes play a very important role in your engine, as they are responsible for supplying fuel from the injector lines to the injectors. And as injectors can wear out, so can the connector tubes, as they are also exposed to the high pressure fuel being forced through them. Any time you replace your injectors, it is highly recommended to also replace all six tubes. SOLD INDIVIDUALLY, FOR A COMPLETE SET, PLEASE UPDATE THE QUANTITY TO SIX.

Connector tube serve two very important functions:
- The spherical end of the connector along with the injector body inlet passage form a high-pressure connection. Leaks at this connection result in high injector return volume, hard starting and other performance problems.
- The injection line end of the connector has an edge filter that will prevent "large" contaminates from reaching and damaging the injector.
Edge Filter Details
- A common rail injector has internal clearance tolerances in the 2-3 micron (ŽÂ¼m) range. A human hair is about 60 ŽÂ¼m thick. Without magnification the smallest size we can see is 30 ŽÂ¼m. Common Rail engine fuel filters normally have a 5 ŽÂ¼m rating. The connector edge filter will capture particles 30 ŽÂ¼m and larger. Overtime some of these will break down into smaller particles and go through the injector causing a reduction its operational life.
- Edge filters will wear in operation letting contaminates larger than 30 ŽÂ¼m to pass on to the injector causing damage and premature failures. Edge filters cannot be visually inspected for wear because once removed the connector tube must not be reused. The only way to insure protection from contaminates larger than 30 ŽÂ¼m is to install a new connector

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.

Its alright
Color: Black, Size: 5X-Large
True to size per the size chart. The fabric is soft but it it feels cheap to me. It attracts lint but you can brush it off easily so its not the cheapest material I've dealt with. Also, it is opaque (not see through).
There is no front/ back indicator either which is indicative of a cheap shirt in my opinion. Would be friendly for tag sensitive people (to stay positive).

Fuzzballs get wearing once
Color: Black, Size: X-Large
Very smart to wear, but the quality is terrible so after one wash the collar start fraying and fuzzballs start forming.
Very disappointing.

Nice sweatshirt
Color: White, Size: Small
Really happy with this sweatshirt. The material is soft, warm, and has a nice thickness without feeling bulky—perfect for crisp fall days and layering in winter. The quilted texture and mock neck give it a more polished, upscale look than a regular sweatshirt. Fits true to size, and the color is vibrant and unique. I like the quarter-snap buttons and chest pocket for a little extra style and function. Easy to dress up or down with jeans or boots, and works great for everyday wear or going out. Definitely a solid addition to a fall/winter wardrobe.
