Default Secondary Air Pumps P0491 and P0492

IHi All,


I have replaced the secondary air pumps on my 2004 CTT.. I can reset the CEL and it will remain off for about 2 days... Then back on again.. The pumps are new.. I suspect vacuum leak...


Can anyone provide info/pix of the vacuum line layout and what exactly to look for... and perhaps confirm that I am on the right path or correct me if not.


I have noticed that the CEL always goes off when vehicle is warm, after running for a while.. Where as I would suspect this issue to be when vehicle hadn't run for a while...


This may be my last electric gremlin to resolve.. I hope.


Thanks
