Gained 2 mpg by replacing broken vacuum hoses

Went from 14.5mpg to 16.5mpg now

It started to get worse and worse gas mileage the past year and it seemed to have bottomed out at 14.5mpg no matter how I drove.

I noticed the hose ends were cracked for the PCV valve on the driver side. The breather hose on the passenger side was also cracked. I got hosed from the dealer for $40 on the breather hose because it has a 90 degree bend and a standard automotive hose wouldn't work.

Pretty much stuck at 16.5mpg after going through 4 tanks.

 

Pictures of hose locations?

 

Just curious - why couldn't you use two pieces of hose and a 90 degree connector instead of being hosed by the dealer ?? Thanks. Curious George.
