EGR hoses

In the two pics below I circled the hoses in question. Going left to right the first & third ones are crossed. Does that make a difference?

 

Far left and right are rolled per what I have on my 96 2.7l. Not sure what the ramification would be. I’d swap them.

 

I did. Thanks. Not sure when that happened. I just had the EGR system reinstalled by Toyota dealer here.

What is that you have spliced into your hose coming off the R port?

 

Looks like a check valve or filter. I don’t have one of those on mine. Only thing I’ve done there from stock ‘96 was replace the lines.

 

Does anyone know if this is the same vaccum routing diagram for a 2.4 on a 2001 ?

 

I believe old silvers is a 2.4, what he pictured.

 

if this helps
