I know I should not be celebrating vaporlock but it was good to have it happen. Keeps us humble.
I hav fuel injection so I am pretty sure it was not on the 17psi side of the pump. However the pressure dropped to 5. I believe this was because the pump was cavitating in bubbles because bubbles will compress and keep the pressure up. (I have bubbles in my oil line for my oil gauge). Of course when the pressure drops to 5 hard telling what was happening on the high side.
It never stopped but did a lot of surging. Pulled over and cracked the gas cap. Pressure but no boiling sound but it kept venting long enough to make me believe ther might be boiling. (yes I had ethanol and don't really care) i reached under and felt the tanks. I was underwhelmed at the temperature. They were warm but it would be a stretch to call then hot. We let it sit for a few minutes and went on. Had to stop again a little later. After that I found that if I just eased up the hill in first gear at about 2400 I was ok. 2500 and it couldn't keep up. I had been running in first gear at 3100. (3.21 final drive)
Man that pass is a grind.
So there is my report. I am now one of the club,
1. Still don't care about ethanol
2. I might begin to consider the possibility of in tank pumps, maybe.
3. I am ready to consider that Fuel injection with a return can heat the gas up by the engine and then dump it back in the tanks warming the gas.
