One of many interesting rock formations on our route

On Thursday, Aug. 11th we left our site at Cadillac Ranch in Bluff and drove to Provo – a drive of about 300 miles.  It seemed like it took us forever.  Not knowing where there were gas stations we kept filling up after only about 100 miles so we wouldn’t get too low.

The weather was a little hot – low to mid 90s – but the coach ran great except for a couple of cases of what seemed like fuel starvation for just a few minutes at a time.  One very curious thing happened along the way though.  It seemed like it was vapor locking or starving for fuel and Carol suggested what her brother told her about loosening the gas cap to break a potential vacuum in the tank.  I had just read about someone having that same problem on the GMC forum so I decided to give it a try.

We stopped at a rest area – more than 100 miles since the last fillup – and I loosened the cap and immediately heard the rush of air I hoped for – but instead of rushing in, the air was rushing out and was followed by the flow of hot gasoline, quite a bit of it.  I quickly put the cap back on and stopped it.  I loosened the cap again and slowly let the air out but there was a lot of it – so much that I again got gasoline flowing again when I let it go too fast.  It took at least a minute or more to slowly let all the air out.  The problem did not recur but I am puzzled about what caused pressure to build up in spite of the very leaky vent line in the rear driver’s side wheel well.

We got to Utah Lake State Park about an hour and a half later than we would have liked – mostly due to the frequent stops for gas and the construction along the way.  The roads were good, the scenery was beautiful the whole day and the Utah Lake park we chose to camp in was great – see Carol’s review in the RV Review section for photos.
