For a few weeks I have smelled a fuel leak. Can't see anything in the valley or on any return caps. Yesterday drove maybe 70 miles and felt my mileage was poor. Let rig sit a few hours and drove to store and saw a trail of something leading back to my truck. Truck was parked on a uphill slop too. Came out and saw a puddle about the size on a soccer ball under the rear of the engine. So today turned on the ignition till the electric fuel pump came on and run it but no leak found. Cleaned off a dirty number 8 injector but still no leak. Ran engine but no leaks anywhere. Got under engine and found oil on the trans pan and looks like it came from the oil filter. I have always had issues with filter leaks. With the oil cooler header off many years ago I checked it for burrs or holes in the seal surface. None found. Draw filed it anyway. Still nothing showed up. So I used my 18 inch channel locks to check howe tight the filter was or was not. It was loose so I turned it another 3/4 turn. Found what looked like a loose motor mount nut. Those 18 mm nuts are tuff to get at. Tightened all 4 of them. Only one each was loose on each side. Now it rest time and thinking whats next. Still thinking about the possible fuel leak. Pump is dry too. Even the weep hole is clean. We will see later on...
