BF225 flakes in filter?

First i have to say this website is a hidden treasure. I just got done (after 3 days) changing my VST HP filter and draining the gas out of the VST. It took me forever (I did strip the screws and now have to look for new ones), but thanks to this website I got it done.
The question at hand; I have a 2004 Proline w/ 2004 Honda BF225 (2004 also). I found some rust colored flakes in the water/fuel sep that is in the engine (the first yellow bowl that the primer bulb feeds to). After that I looked at my fuel line from the fuel/water sep on the boat to the primer bulb and it was completely deteriorated. I put on a new racor fuel/water sep (the one in the hull), new fuel lines from that to the primer bulb, new fuel lines from the primer bulb to the first yellow bowl in the engine. After that the boat ran fine and was in great shape. Now I have rust colored flakes in that bowl again. Where would that come from? If it's in the aluminum fuel tank or the lines from the tank to the racor then wouldn't the racor filter pick it up first? Any help is greatly appreciated and thanks in advance.
On a less important note...can anyone tell me what size and where I can get the 3 stailless screws that held the High Pressure fuel filter housing on? Thanks

Mike

AH, the joys of ethanol laced gasoline!

Yes, the Racor should pick up junk from the tank. Did you change the pump up bulb too? If not, you should have. Internally, it was likely as damaged as the fuel lines were. If that was replaced, then drain the Racor filter and examine the contents very carefully - is it hard or spongy? I get the spongy stuff, and apparently it is some sort of fungus that can grow in the moisture that accumulates in an open gas tank. I regularly get that rust-colored crap in the bottom of my Racor filter, but that is as far as it goes. Because of that, I replace the Racor every year.
 
Chawk,
i did change the bulb also and that's what had me concerned. Could it be from the gas tank in the boat? It's a 2004 aluminum tank. it's a spongy rust colored flake. When I took off my old above deck gas line, the inside of that was completely deteriorated and lined with those flakes. Any other ideas? i'm always thinking the worst, but seems like you know a lot about these hondas. Thanks for any help.
 
Well, if you have a new Racor 10 micron fuel-water separator installed before the pump-up bulb, that should catch any of the crap coming out of the tank.

Does your on-board fuel-water separator have two wires coming out of the bottom? If so, that filter has a float and float valve in it that sets off your "water in fuel" alarm if water gets in there. It is possible that the float has deteriorated or something else is hiding in there.
Here is the procedure for checking (all covered in the workshop manual and probably covered in your owners manual)...
  • Disconnect battery.
  • Remove engine cover
  • Disconnect ALL connectors to the ECM (Don’t know why this is necessary, but that is what the manual says.)
  • Disconnect the 2 prong connector to the filter and remove the wire harness from the clamp.
  • Clamp the two fuel lines and disconnect them from the filter.
  • Remove the fuel-water separator from its rubber suspension harness.
  • Remove the three 5 X 12 mm pan screws and separate the cup from the body of the filter.
  • Clean everything out well and check that the float moves up and down freely. If it doesn't, replace the fuel-water separator. If there are signs of float deterioration, or the filter does not appear to be totally clean, then replace the separator.
  • On reassembly, be especially careful reseating the O ring. If there is any damage or compression, replace it. Torque on the pan screws is 2.5 ft-lbs.
If everything in the on-board fuel water separator is crispy clean and working properly, then I'd go back and re-examine the Racor. It's not doing its job, which I find highly improbable.

BTW - I'm just a Honda 225 owner and take the time to do a lot of my own maintenance. My engine is a 2007 and is mounted on a C Hawk 25 DLX. I put about 250 hours on the engine each year.

There are some real experts on this forum who do this stuff for a living and know vastly more than I do. Hopefully they will kick in if they have some different ideas.
