Mercury 525efi fuel filter
Is there a known problem with the fuel filters on the Mercury 525efi's or do I just have bad luck? I had port motor filter crack around the welded fitting on the discharge side of filter last month. I thought they might just be getting old (I only had boat for a year) so I bought 3 new Mercury filters @ 40.00 each to replace them all. Sunday I had the center motor filter crack in the same place as the first time. Let alone costing 40.00 each this problem can get serious in a hurry since it is dumping alot of fuel on top of a hot motor. Has anyone else had this problem with the filters?

I would check the mounting of the fitler and play on the lines, the later 525 EFI's switched to a canister type filter, not sure if they did because of problems with these or just engine evolution.
My 575's have the same fiter, when I changed them both ends of the lines have play for flex, I would make sure you have flex as well and also make sure you are not over torquing the new filters

WOW! Amazon 3 filters = 34.00 with shipping, compared to discounted price of 113.00 that I got.
Fuel inlet line is rigid & the filter is secured with bracket but the outlet line (side that is cracking) has flex in the line.

I am having a heck of a time getting the lines to seat and not leak. There are not any crush washers or O-rings that I can see in the original filters and I have tried 3 brands of aftermarket filers. Really crazy that the line is solely relying on fare nut to locate and seal. Does anyone have some insight or solutions?

I had no issues using the ac delco filters. The fuel lines on these boats are nothing special, standard stuff. I actually had an issue with one of the merc filters to years ago, had to really crank it down to seal.

If you can ruse a rubber clamp to bolt or mount to the motor it has help. Also if I knew how to post pics these filters from Merc are junk internally as they would come apart also and offer no filtration. I do not buy them anymore from Merc -use the Mallory marine apps and have had better luck with them. The merc ones are from Mexico.
