Now, this has nothing to do with my FASS's operation, but I found it quite intriguing...
On my trip to UT a couple weeks ago, I was running around 15psi idle on the flat lands during the trip out. I got into the mountains, and I was holding 9 to 10psi at idle for whatever reason. When I got back out onto the flat lands for the trip home, I was back to 15psi at idle.
Now during this oddness, my low pressure light (set at 7psi) never illuminated (it is working BTW)... so I wasn't pulling the pressure down much when pulling the hills... I worked 5th gear hard a couple times just to see if it would pop the light on... never came on. The truck ran fine, pump ran fine, no weirdness other than the lower than normal psi.
So, what is the explanation for the low pressure at higher elevations??? Was it the fuel?? Was it the higher altitude (that should have made no difference in this application)??? Was it the guage???
Ideas??
Again, it isn't a problem, but I would like to know what others think the cause of the drop was...
