took Dat Boi (my nickname for my 75 z) to Smiths Station AL for a family visit, 400 miles each way, avg 75-85 depending on interstate traffic. slower up hiway 280. Avg 25 MPG, found a ethanol free GATEs filling station at mile 439 in Florida on I 75 for those interested in where to get gas. No problems at all until the return trip. It was hot and I was running the AC, Stopped at the Gainesville rest stop and noticed carpet on driver side was damp, pulled it up and found it soaked from the tunnel on down. A quick taste test (yum) showed no signs of antifreeze so I figured must have been the condensate. I was not in a good position to work on it, so turned off the AC and drove the 70 or so miles with out it. Looked thru my stash and found the coupler needed (EVAP box to drain pipe) to replace the broken one. got all the carpet and jute out and thoroughly dried the driver, lifted up the carpet on the tunnel and ran a fan all night on it to help air it out. took a ride with AC on, drove for about 20 miles and when home I could see the water dripping out of the drain pipe, YAY, and the tunnel and floor board was completely dry. Hopefully that is the end of the leak problems, I am looking forward to more long trips. These shake down trips seem just the ticket to find little problems.
