Thanks Go... Appreciated.
Truthfully I am interested in the fuel rail assembly. All the other builds, from TPS, Idle sensor, Throttle Body, etc... I am cool with. IMO the only way to get to remove the common chamber is to remove the Fuel Rail. Some have posted you can wedge the common chamber up(?) and then slide in the gaskets(?). By my experience, sounds sketchy, and I want to clean out the EGR line.

Some might ask why not just have an Isuzu dealership do it?
I don't trust them, & I am the third owner, no warranty.
