Well, I am on my 2nd LP. I replaced the first around 70K and have just over 100K on the truck now. Last time I checked with a manual guage I had 14-15 idle and 9 WOT but I need to check that again.
The first one failed before I put my FMS on and was seeing 7 idle, on and off, like an intermittent pulse. I replaced it with the second and it has about 30K on it.
