A few weeks ago I asked for help in diagnosing a fuel starvation situation.
The problem turned out to be a failed electric fuel pump. The pump was on the coach when I bought it in 2002 and has always worked in the past so I didn't suspect it.
After eliminating other possibilities I determined that I had power to the pump but it would not run.
I removed the pump and spliced the fuel line. Last Thursday it was 111F in Red Bluff so I was thankful that it was only 107F on Friday when I made the 80 mile trip back up the mountains. The coach made the grades with no fuel starvation symptoms.
The only changes from the previous trips were higher ambient temps and no electric fuel pump.
I assume that the failed pump restricted the fuel flow. I ordered a replacement pump and will install it, just in case. But it is good to know that I'm not getting vapor lock with high heat, heavy engine load, and cheap Arco gas.
Thanks to all who replied with suggestions.
