How to check fuel pressure?
How do I go about checking the fuel pressure at idle and at WOT? The more I read, the more I think I have a bad fuel pump.<br><br>Also, how much do these pumps run?

I'm just getting pretty poor mileage. At last fill up I calculated a little over 12mpg.<br><br>Also, my truck doesn't seem to be as powerful as it once was.

Try checking/replacing the overflow valve, too, before you consider a new pump.<br><br>Lift pumps can be had for about $150. Don't even think about replacing that P7100!
