fuel flow

[master chief]

I posted a message about a problem with what I think is a fuel starvation problem.I have a 200 omc seadrive 1986 mod.The engine runs good to 3000-4000 rpm.some times the rpms will vary before the engine starts surging,&slows down.If I run it @ 3000-4000 it usually runs good.Above that speed it starts to act like it is starving for fuel.I put an inline fuel pmp in, to no avail.I removed the fuel intake fitting off the tank.There is no anti siphon vlv unless it is at the bottom of the pick-up.I will make sure the fittings are sealed good,but otherwise I don,t know what to do.Any ideas on what I might have missed?Any help would be appreciated.I apologize for the long winded post.<br /> master chief

Re: fuel flow

I hate to tell you this, but if the fuel delivery system is 100%, it is time for a compression test.
