Mercuiser cool fuel filters
 

Ok Im sure this has been ask a bunch. I did a search and couldn't find and recent posts. Looking for replace both the filters the paper one and the white plastic one. Man these things are expensive. So where is my cheapest place to get them ?

your not going to find them period and they are app specific to Merc. And the micron ratings needs to be exact. Especially for the white disc filter. Merc dealer or I have these on hand all the time in the dozens because they need to be changed once per year bare min especially at the start of boating season. . How many pairs do you need ? The more needed -- the price goes down if you want to save.

2 pairs. If I get more I will just put in safe place and will never be able to find later.

I'll assume your talking about Gen 3 cool fuel (did not say)

Not part of your question but I have a hard time understanding why folks stay with the Gen 3 and just get rid of it and even go back to gen 2 with standard water separation filter, or go after market

the gen 3 cool fuel uses a different ECM tune and it all has to due with FUEL PRESSURE DAMPING thats just one of the reasons among a few more

I look forward to seeing the data
Manual 31 = 46 psi @ 1800 rpm
Manual 32 = 46 psi @ 1800 rpm
Manual 40 (cool fuel Gen 3) = If fuel pressure exceeds 44 psi (303 kPa), replace the fuel pressure regulator.

fuel pressure psi and fuel DAMPING -- is 2 TOTALLY different things --- Damping the injectors pulsations and damping the psi pulsations and any spikes. They are not even close the same thing. I am teaching you something here run with it and teaching all something if they did not already know this . Like I would not know what I am talking about. Anyways anymore questions ?

different fuel set ups and even different types of fuel LINES have different damping effects - the GEN 3 box has its effects as well plus keeps the fuel pumps basically cooler because they are submerged in FUEL all the time.

Submerging the fuel pumps in fuel all the time reduces VAPOR lock, reduces heat - reduces wear of the pumps themselves, reduces air and cavitation of the fuel pumps - plus the fuel pumps always stay primed of fuel - that alone adds to longevity to the fuel pumps --- if the fuel system is maintained properly all the time.

Also its easier to maintain fuel pressure when the fuel pumps are submerged in fuel. Again less cavitation and air entering until one runs very low on fuel level.

Do I like the gen 3 cool fuel --- NO I DO NOT --- very poor design and not worth the money but its a stock app and what comes with the merc engineered design including the ECM / PCM OEM locked tune.

Your funny
Damping "taking out the pulsing of the pump" can be smoothed many ways

BUP you probably are one of the smartest guys here (on the 496), but there is no need for the dramatic.
There are issues with the Gen 3 pump including paint. We just discussed the paint issue, and it was you which brought up that the paint issues was not over (another insight for all of us). I contacted Merc and they confirmed (sort of) that they went to anodizing the inside of the pump (I think) in 2015

We discussed the crank sensor (496) and I listed 2 part numbers and one you said was wrong and were correct, great catch. The other was one you went to O'reillys and ordered one a month or so ago and have not come back as to if it would work or not. Great work, you are the guy, have the greatest following, but yet it appears you take offence if anyone trys to figure out what could work that is better or cheaper.

I don't get it, and just maybe never will

Since alldodge your changing directions and I guess dogging me about different past posts here - for starters -- The cool fuel gen 3 you wanted to argue with me about that as well about the internal paint. I do not get it from you - - The subject at hand here in this post was --- about the PCM / ECM locked OEM tunes. With that said, I am telling you that the PCM 555 for GEN 2 cool fuel compared to GEN 3 cool fuel is different PCM tunes / calibrations -- Do you really even know ? You still want to argue this to no end then point fingers about past posts . . .So for the fact of the matter did you know -- Merc even has different PART numbers for the PCM 555 for the GEN 2 cool fuels applications compared to the gen 3 cool fuel applications - The PCM tunes are not the same period nor are the part numbers.

Anyways Back to the gen 3 cool fuet had peeling paint all the way to 2015 and that was for the CATALYST ENGINES in the mix, but again you continued to argue with me about no they did not as YOU believed all painting stopped in 2009 for the gen 3 cool fuels internally. I have no idea why you do not listen and would rather argue as it seems. --- so you ended up calling merc and they told you 2014 they went to anodizing the top portion only and no more paint . Actually it was 2015 still had paint. after all that -- you finally believed me but only after Merc told you as well.

I have no idea why you want to make a seen on my posts this year. I am lost about your motive here and where your info comes from. I hope maybe you see where I am coming from in this matter . I take what I do seriously and try to post very solid info as it does not come from google. And for the record the 496 is not my only expertise. I work on alot more than just the 496.

So now you have another beef with me is cam sensors as I proved you WRONG for what you listed with that one. a couple months ago - you were so far off with that I still do not get it - you know google is not always correct right ? Nor is Rock auto, . , I still can not believe you went from me telling you that one can not just change up fuel systems completely as the PCM / ECM 555 locked tunes are not the same between the different fuel system set ups thru Mercruiser to calling me out about cam sensors. So you want to rehash that one again. I am lost at your motive here. .

I do not get you at all and why you argue with me about everything. Why is that ??, . You totally argued about the brass drain plugs installed in brass housing was not good as installing Stainless steel drain plugs into brass seriously you want to disagree with me over that as well.. I do not get that one. . Your info was from google and it was about Stainless plating from a chart inwhich has nothing to do with marine stainless steel applications. .So I bet you will reargue about the stainless plating chart now ?

Anyways here is the gen 3 cool fuel PAINT -- ISSUES The gen 3 cool fuel started in late 2005 thru 2015 with internal paint. The Paint issues Info in the Service Bulletin below. Its dated 2016, So do me a favor and report I gave you the info on all those other websites,

thank you because you were reporting all the paint stopped in 2009. That is not correct. The SB for the win and for you below - hope you can open it up --- again setting the record straight so we do not have to argue this one all over again. .. So whats next out of you -- the cam sensors or the PCM tunes are different between the cool fuels because they are whether you think so or not..

Dang I was just looking for a cheap place to buy the filters lol.

Your just a guy that doesn't like questions other then, how did you become the best in the world

Sorry outta control for the side track, will see if I can find a place

Here is cheapest I've found and is Merc, may be able to find aftermarket a bit cheaper
https://www.ebay.com/itm/Genuine-Mer...5.c10#viTabs_0

Thanks, yea Im not a fan of aftermarket parts. 76 bucks including shipping is pretty cheap. I had forgotten about ebay.

^^^^ well sorry about all the miss directions here. Thanks as well but in all fairness your screen name is outta control - so this thread fits. could not have done it without alldodge refuting everything I say for this whole year. .

Bub / alldodge ,

im new on the forum and been a industrial engine mechanic for past 30 years , i must say i enjoy the banter as ive been involved it it all my life, working with other mechanics challenging each other in a friendly way and having FUN,


cheers, keep up the great posts

I guess thanks for the compliment

BUT I DO HAVE TO MAKE ONE VALID POINT here I am not that far advance as of yet but working on my youtube patch like whomever. Then the next steep is the google patch. Got love it getting out mastered by these dudes. Yeah right . That will be the F in day. https://cimg9.ibsrv.net/gimg/www.off...e9f4219bd8.jpg
