Installed New LP

Just got done replacing the LP and wow! The tapping and knocking I was hearing before have gone away completely, and it feels like the truck has a lot more power! Just home I caught it in time before it did too much damage to the VP....

Hearing an LP does not mean it is pumping. I had a stock LP go bad out of the box in a week.

Better get a fuel pressure guage.

If your truck was running a negative fuel pressure then you would in fact see an improvement in engine performance with a new lift pump. I've seen a couple of trucks that this happened to. Both trucks now have well over 100,000 miles on the original VP44s.
