2003 W208 Intake Vacuum Front Hose
Guys,
Kind of in a pickle. Car was running rough and giving bank 1 lean errors. Stared checking vacuum lines and found breather hoses and most vacuum lines NG.
The nipple on the drivers side for the breather tube was 1/2 broken. I epoxied to am cover and Ok.
There is a vacuum hose dead center Front bottom of the intake. It was completely cracked and disintegrated. Have most of hose out but, goes up into
the bottom of the intake. How do I replace? I can find no barb. Pulled intake and seperated and cannot see any way to access. How is the hose held in?
Any help would be appreciated

Update, Sat on garage floor and could not separate internal baffle to get at it. Used pics to chisel away at the hose end. Took about 2 1/2 hours. Did not expect to have to remove the intake to
replace a vacuum hose so did not have new intake gaskets or injector seals/o-rings. Used form a gasket for the gaskets and tried it. Like I thought Injectors leaking like crazy. Leaving town on business
for 2 weeks so will tackle again then. ordering injector seals and o-rings. Glad I have the truck.

Updat:
All back and running. Got the injector seal kit in while I was away and installed today. New micro screens, orings, and lower cap. pulled fuel rail into garage and cleaned
and installed injectors. Triple checked that all were seated and clips corrected correctly. Put all back together. No leaks. Test drove and checked again all OK. Put all
back together and all is right with the world.
