Today got ruined by the blue Burb leaving me stranded. It started sputtering, then I had no power. Acted like I was running out of fuel, gauge said half tank, but I couldn’t say for sure it was working. I could hear the lift pump (fuel pump), so it seemed to be working. even had the sound like it was picking up fuel, it would change pitch. Anyways, I crawled down the highway should at 20 MPH for the last four miles during rush hour. I got to the parking lot just off the highway, called for backup, then did some investigating, the fuel filter bowl has a drain off the bottom so you can get any water or junk out easier. When I cracked that with the engine running, it stalled out and no fuel came out. I could still hear the lift pump, so I figured the gauge was wrong and I was out of fuel. So when backup arrived, we got a bunch of tools and some fuel and when I added fuel, it started back up, at this point I checked for fuel flow out of the filter housing and it was flowing fine. This made me think I either had run out of fuel, or the lift pump doesn’t run properly when it gets hot. Took the Burb to the closest fuel station, the tank only took 22.4 gallons and it is a 42 gallon tank, so fuel pump it is.
