Greetings all, it been about 4 years since I’ve been on here-so much knowledge gained I guess I got by. Anyways I need some help.
My engine won’t start after being run for about 30 min or so. I’m getting the classic, some say, bubble at the prefilter IN line #1. I go to start and this line actually drains down very quickly then refills when I stop trying to start. I don’t think I’ve seen this before.
I’ve attached a video link, https://youtube.com/shorts/fywkBKK7Ob4?feature=share
I changed all the plastic lines and prefilter(w/o-ring) with new from PP and sure I’ve got them routed right per Diseasel300 post from 2017. The intake and return lines are on the right nipples on the firewall. Now I will say I’ve got a leak on line 3 at the lift pump I’ve got to sort. Anyone seen this phenomenon before and ideas of what did wrong/solutions?
