Replace o-rings on HOSE FITTING for cool fuel gen 3

I am pulling my older style hose fittings on my gen 3 cool fuel module they are slightly dripping.
Anyone have the size or part number for these on the white plastic plugs.
I would like to have them on hand before I pull them,
Thanks

I don't have the answer to that question but what I can tell you is the problem is not the O-rings but corrosion on the aluminum where the O-rings seal

I will clean it once I pull it apart and see how bad it is fresh water only. Newer to me boat, Just would like to have parts on hand. I know there are other fixes, I will check it out first
 
Mercruiser parts.com enter your engine number and the parts diagrams will be there with numbers
 
Cleaning it up and replacing the orings is NOT the fix for this problem.
Email this guy and ask if he has any SS fittings left. max@traxxion.com
 
SS into aluminum is a no no. Merc offers plastic/nylon for replacements. There is little to no meat there to tap the housing. Bubble gum it together until it fails and then buy an updated housing.
 
I know all about the dissimilar metals. These are a pretty good fix, and mine are doing just fine. That's it for my input, not going to argue with anyone about it.

I stand corrected. I believe they are plastic/nylon.

Still looking for a way to bandaid and have parts on hand before I pull it apart.
 
I'm going through this right now. I just put it all back together and will be dropping it off with my mechanic for installation tomorrow afternoon.

The cheap way: replace the hose assembly with the newer version FITTING-HOSE ASY 865208T02, drill out the holes
where the old hose assembly connected, and then tap for some hose barbs. Connect them with band clamps.

The way I went - the more expensive way: replace the hose assembly with the part mentioned above, and get a new housing already tapped for the hose barbs.864650A14 HOUSING Fuel Module
