Hello all. I am working on an old gradall with a John Deere power tech 4.5 ser#PE4045H468706.
Original complaint was it was run out of fuel.
I am able to get it bleed and have it running strong but after it sits for a couple hours it looses prime and I have to bleed it again.
In the course of working on it all the supply lines have new seals.
Is there a check valve somewhere in the system I need to look at?
I really have no idea where to go from here. Any suggestions?
Thank you for reading.
