91 HRC With 460 Ford 550 chasis, Fuel Injection.
Symptom: Loss of power from 65mph to about 40mph on I80 in Nebraska.
Doesn't get much flatter that that. Temp in the low 70's
We had been crusing for about 2.5 hrs in the afternoon. Had about 1/2 tank of gas when I noticed the loss of power. Thought I might be on a grade or something. Then a small, bearly detectable engine miss/stumble.
I thought for sure it was another intank fuel pump/filter problem.
We were about 20mi east of NorthPlatte and pulled off and into a dinky old Sinclair Station. I had read where the gas in the tank may get hot and cause a problem. I took on 20 gallons. We got onto Hwy 30, and headed into town. I eased it on up to 50-60mph and no problem.
We stopped in town at another gas station and took on another 28 gallons to fill the tank, making a total of 48. I have an 80 gallon tank, so I still had 32 gallons onboard when I had the problem. Seems like a lot of gas to me.
We cruised at 55-65mph for another 2000 miles out to Denver and back without any other problems. I always made sure I got gas at about 250mi or so taking on 40-45 gallons.
So was it Hot or Dirty Gas, vapor lock or the dreaded pump???
If you notice the problem, pull off and get some gas to cool it off.
It may help.
