Looking for some advice here on my 1KZTE. She runs great however I noticed an issue last month on start up. She started normally but was leaking fuel from the pump. I couldn’t determine exactly where it was coming from. I had recently done the mod to stretch the spring on the banjo bolt so I thought that may be it. I tightened it a tad and the leak stopped so problem solved…I thought. Few days ago the problem resurfaced but the leak stopped itself 10-15 minutes later. I’m starting to think this is temperature induced as both times happened when the truck was parked outside and it was extremely cold. My guess is once the truck and fuel warms up the leak stops. Are bad O-rings more susceptible to cold temps? Should I just go ahead and have it rebuilt? Thoughts on mechanical pump?
