Filter replacement for a 2004 225 HPDI

[Carlos H]

Well, had noticed that when I would hammer down to get out of the hole, I would get hesitation and almost felt like the engine would "miss". As I had this problem before, under warranty, I knew what I needed to do.

I had to spend 200 bones on fuel filters for my 'hammer.

I bought:
High pressure fuel filter $88
VST canister gasket $31
low pressure filter $5
fuel pressure regulator parts and filer $36
Fuel pump filter $25
MAR FUELF FILTER $20

Replacement of the filters was prety easy, just took my time as I had them replaced with a fuel issue earlier on.

Needed few tools and followed the instructions here on how to pull the high pressure filter and the VST tank. Did a slightly different order, but came apart just fine.

Here is why it ran like crap and just to let you know, I use Ring Free each tank and also use the blue stuff from starbright to help with the ethanol phase seperation issues. Every spring I change the water seperator and will move that every 6 months now.

I found major mess in the VST tank, a piece of the old gasket from the VST tank. When I pulled apart the high pressure filter it had some water in it and some black sand looking crap. The high pressure filter itself when I pulled it out, was black but not that bad looking and no chunkies came with it.

If I was to do over, I would change just the fuel pump filter, the VST filter, low pressure filter and the water seperator filter.

The last set of filters lasted about 200 hours as I was planning on doing my 200 hour check this winter. This is just a guess on hours as I do not have a smart craft gauge.

Good luck fellas

i did the same as you but i just cleaned the vst and it helped a ton

I had thought about that, but I am at 200 hours and the complete filter change was needed as it is.

Let me guess you have a black fuel hose from the tank to the motor?

If so you should replace it. Mercury makes a gray hose with blue print with bulb that should stand up to the e10 much better.

Great post and pics!

Connor,
yes, but acording to Ranger it is ok for E10. is that an incorrect statement? I have NO issues with replacign it if that is not true.

I would take a good look at the black fuel line. Cut a small piece off and then split it open and look to see if it is degrading any. I think that it all will begin to break down sooner or later.

[Carlos H]

So, I know it does not have the liner issue..if I cut off a piece, what am I looking for???

Look to see if you can rub the inter hose and have some particals on you finger. Make sure you use a clean finger!!
I am not sure where else the little bits of black stuff in your pic would have come from if not the hose.
