The 1st PE pump I ever purchased I installed on my '01 daily driver. It has NEVER missed a beat. I'm not sure how long it's been, but I'd guess 14-18 months . Contrary to popular opinion, I wired it "key hot" via a relay. On 90 degree + days ( a blue moon around here), it does take an extra . 5 or 1 second extra crank time to start. I've since "warranted" several of these pumps with different symptoms. I am suspicious of the intermittent signal sent to the fuel pump from the oem harness. PE FLAT OUT quit selling these pumps for our application when they determined they had a problem. They made a few design changes, did more testing & now feel it's a reliable option for us. PE has been a pleasure to do business with, even under warranty circumstances..... Rip
