Good point. During this operation, I went over all the piping connections and did not find anything other than the exhaust pipe on the downstream side of the E Brake that was erroded and in dire need of replacement.
After I finished the work on the exhaust, I took it for a test drive with the bedroom cover off and my buddy with his head in the engine compartment. This was mainly to check on the seal of the E Brake but during the drive, he could not hear any "air loss noises" of any kind.
I have talked to others with the same engine and weight combination and I have not run into anyone that honestly gets much better than 7 MPG.
What would you expect from a typical 8.3 ISC weighing in at 35,000+- Lbs?
