I had my second lift pump fail in about as many years. I had 6.5 psi at the head during this mornings preflight, which is what this pump has always read since new. Pulling my trailer on the highway, I noticed my filter light pulsating on during high engine load. I Pulled over to check it out and found the pressure down to 3 psi. Hauled about a hundred or so more miles and managed to get her home, checked again, now she’s down to 1 psi. I changed the filter, blew out the pressure lines for each tank, and the feed line between pump and head. No change. Definitely the pump. I always make sure that the arm is correctly under the cam lobe when I install these things. I’m tired of replacing these garbage lift pumps every year but, as far as I can tell they are all made in china these days. Is going electric my only option?
