Motor has been flawless. Started it one day to run it and move it. Ran for 30 mins. Turned it off. 2 days later I went to start it and nothing. If I bleed the injector lines it will start and run great. When I shut it off, I can immediately start it back up no problem. If I wait 10 or more mins, it won’t start unless I crack the injector lines and bleed it again. I have replaced the inline fuel filter in the frame rail, replaced fuel pump and replaced 2 check vale’s going into fuel filter housing. Still does the same thing. The other fuel filters have about 3000 miles on them. I don’t see any fuel line leaks. I took plate off above tank and it’s a brand new fuel tank.
I know nothing about MBE engines…. But I found this interesting post
on another forum where the guy had the same problems you have.
It kinda points to what Jose lack is pointing at, check and bypass valves.
Let us know if it was helpful…
