Just read the original owners manual on the subject of how to bleed the system. I didn't bleed the fuel filter.... First thing tomorrow after church.

Universal fuel filters and no run
Hi All,
I'm researching and racking my brains as to why my 24hp 5424 won't stay running past 5 minutes at the dock. Here's what I did. Replaced 2 fuel lines from the tank to the water separator, and from the separator filter to the electric pump, replaced the water separator filter and the engine fuel filter. Filled the filters up with fuel before screwing them on. I've tightened the lug nuts out of both filters (figure of speech) and had to bleed the system a little at the fuel distributor. Got her to run, had to bleed it a couple times, but always at the fuel pump. After running for 5-10 minutes at the dock, we motored out the long fairway, got to the channel and she died (ran of out fuel). Got her to an end dock, bled the fuel distributor, again it would start, let it sit through various RPM ranges, shove off and within 5 minutes, running out of fuel again. I'm at a loss.
Help, thanks, Dave

Re: Universal no top RPM after fuel filter change
Well I got the beast to run after I bled the filter module, then the injector pump and even the injectors. Runs like a top, 600 RPM idle in gear all day long, purrs trike a kitten... Until I try to open her up and RPM stops at 2400 (cruise is 2300, max is 2800).
Now I know I'm going to get lots of hypothese but my bottom line is "if it worked as advertised BEFORE I changed 2 filters and 3' of fuel line... All of a sudden - it's not a rope wrapped around my prop shaft or bad fuel.
This is fuel related I'm very sure. Who else has been here?

Re: Universal no top RPM after fuel filter change
Rx: re-check the gaskets on the filter; and, if you have them install NEW and 'lubricate' the gaskets/O-rings with oil so that they dont 'deform' when you 'tighten down' on the filters.
If you removed any 'fittings' when replacing the filters carefully check the 'nut' on the fittings to be sure you havent 'cracked' one when retightening ... ditto, be sure that havent 'stripped a thread' on a nut.
The highest probability is that when you reinstalled your 'filters' you pinched a gasket or O-ring during the installation and now under HIGH VACUUM as would be expected to develop in the fuel lines as generated by the lift pump when going toward FULL throttle position, there is a 'small' amount of air being 'sucked in' and past the incorrectly seated gasket or o-ring.Well I got the beast to run after I bled the filter module, then the injector pump and even the injectors.
