Well story goes I went to Mount Evans in Colorado at 13,000 feet today and when I got way up there about 11,000 or so my fuel pump started to let out a fairly loud whine. Is this normal for a dramatic increase of elevation for the fuel pump to sound like that or is this the first signs of my ten year old fuel pump going out. Just want to know if any of you guys have ever dealt with this issue!! Thanks for the replys in advance...

 

Just wanted to bump it up so more could look at it to try to help me out thanks!

 

Still hoping to see if anyone can answer this thanks!
