Truck still runs after starting just fine, pressure are good at low idle and high idle. But she takes about 10-15 seconds to gain enough pressure to start. Right off the bat I knew about fuel pressure regulator on back of head. Old one and new one looked different as far as where the inside plunger sat. Replaced fuel filter while we were at it. Then someone snapped the knob off of priming pump when he decided to use a two foot chain wrench to loosen it to prime new filter. Made him go get a new priming hand pump from CAT. Now I can get about 5 PSI, anything above that and you can hear it drain to tank. So I assumed that fuel pressure regulator was factory set or am I a dead cat?? Or is it possible fuel pressure regulator was smoked right out of the box?? I had to leave that job to go to another but still thinking about it. Any idears???
FL M2 with C7 acert will not hold prime pressure
