you can clean the oem filter for re-use i use brake cleaner and compressed air. or just use a piece of internal fuel tank rubber hose and delete it. then place an inline efi type filter before the fuel rail.

OEM filter cannot be good clean (this is a temporary fix)
because it rusts from water in a bad fuel
This leads to big problems and possible damage to the engine (I measured pressure at full throttle, a large drop from the 50psi up to 40 psi)
because the fuel pump cannot pump enough fuel
OEM fuel filter not sold separately
I'm looking for another filter that fits in size
installing the remote filter (original AEM or AEROMOTIVE around $ 100) requires modification of the fuel system and the abolition of the warranty

mate its fine to clean i suggest you stop refueling with water as no after market filter is going to be any better. you will not find another of the same size. f you are so concerned drill it out and add one before the rail like i suggested.
heres a tip for you, disconnect the fuel hose at the rail place it in a measuring cup, fit the ignition key, measure the fuel it will run for 3sec do this 3 times. min amount is 83mls i have had them below 70mls this is when they start to run sh it, now remove the filter assembly and clean it like i suggested above (before cleaning try and blow air from your mouth through it, then after cleaning do the same im sure you will be amazed) refit and test it again you should now have with a cleaned filter 175mls.
first time this secret has been let out do what you will with it but i can assure you wot speed is now restored

It's not a secret
wash this temporary solution
Rust in the fuel oil filter balls cannot correct it is not stainless steel
After a while the problem persists even stronger
I think that was because of this breakdown of the engine in the offshore race

your worried about a warranty but yet your running it in an offshore race. seems like you have contradicting wants and needs.
you have four options
1.) don't race
2.) use the same crap fuel thats causing this issue but modify the fuel system to use an inline filter with a replacebale element, race the boat, kiss warranty goodbye
3.) use better fuel, retain the oem fuel filter, race the boat and hope your warranty isnt voided
4.) use better fuel, dont race, retain warranty
you can't have your cake and eat it too.
