My truck was throwing error code P0401.
Opened my hood up to check the egr, and the green hose that goes from the EGR valve to the vacuum solenoid is broken off at the connector to the EGR vacuum solenoid.

What is this hose called so I can get a new one?
It has a black boot type connector at the bottom with another hose that goes around the back of the engine.

 

You can go to the auto parts store and use normal vacuum hose. I can't remember the exact size you need, but if you bring the boot part of the hose with you, just match it up at the auto parts store and get a couple feet (or how ever long you need it) of typical vacuum hose. My whole engine has replaced vacuum hoses and it's typical rubber vacuum line hose. It doesn't have to be the original plastic type. I'm not even sure where to buy the original plastic stuff or if they even sell it. It's cheap too!

 

That's exactly what I did, after thinking about it. I got 3/16" 5/32" would have been ideal, but this should give a pretty snug fit as well

Thanks for the quick reply!!
