Redundant Fuel Filters

Having finished a few of the projects on the honey do list I was given a new one this week. Replace of update my Racor 1000rf filters with a redundant set, before we head out the SF Gate. In doing some research I'd discovered RACOR is VERY PROUD of their gear. There appears to be at least two other companies selling a similar product. Has anyone on the forum had any experience with either of these brands and or products :

New Dual 1000 Series Diesel Fuel Filter Water Separator 180 360GPH 30 Micron | eBay is out of China and their unit runs $700 per pair and
Griffin has a pair for $900
GRIFFIN GTB681DM-MA / G1000DM-MA

where Racor wants over $1500. Understand everyone has or had Racor, but looking for any help/history with these other providers good or bad.

Given the prices just buying two new filers and four 3 way valves might save me a lot of money..

Why not go with an original Racor? You're not saving anything by ebay china. BTW, did you see the shipping cost from ebay? It says from Florida, but it's coming from China through Florida.

I'd love to go with Racor but for the 751000, the price is double the FJF from china and $600 more than the Griffin from Texas, as I read the adds. Just not sure Racor is twice as good. I need the larger units for the 6v92T I have on the boat.

OK that makes sense. Regardless, you can get that knock off from Amazon. The freight the ebay merchant is charging is outrageous.

Since most engine happen at the worst time in the worst places and most often from fuel related issues adding cheap filters sounds like you are asking for problems in the future. From my experience you will find out why the China's filter is so much cheaper at very bad inopportune time. At which time it will cost you twice as much to fix the problem then if you did it correctly from the beginning. just saying...

Roll Tide, not to be argumentative, but if the China filter and the Racor filter are the same micron size, and the filter canisters (for lack of a proper term) are both sealed units (once the filter is inside), how is one going to operate any different from the other?

IMO it's not likely that the cheaper filters will collapse or fail in some other way, will they?

I'm just asking. I have Racors on my boat and buy the filters from a source other than Racor. They're Racor branded but cheaper than what Racor sells their filters for.

I've boated for many years and have used "second source" filters rather than the premium brands for all those years and have never had a problem.

Just asking.........

Even the Griffin's out of Texas are considerably cheaper not sure why, but I love to talk to someone who has used them, before I part with my $$

Not sure if fuel filters are rated the same as hydraulic filters, but, in the hydraulic industry you will see filters rated by micron and Beta ratio. The micron states the largest particle that can fit through. the Beta ratio is how efficient the filter is. In the hydraulic industry, top of the line manufactures are over 99% efficient while aftermarket manufacturers are somewhere in the 60% efficiency range. They have the same micron rating, fit in the same housing, but the material used and the density of the material used vary widely. As an example, we have 8 hydrostatic test stands in our remanufacturing department. we use three 5" diameter 10 micron spin on filters connected in series that we changed every 3 months whether they went into bypass or not. I changed to a top line manufacturer that fit on the same housing. My test room supervisor came to me after installing these and told me they clogged up in an hour. We had to replace the elements four times before they would not clog and go into bypass. both filters were 10 micron; the top of the line cost double what the other cost and more than worth it for me

Tony Athens of Seaboard Marine sources a good selection of filter assemblies, and has quite a lot to say about setting up filtration systems. He is a major supporter of and contributor to BoatDiesel and has a lot of information on his site, Seaboard Marine - Custom Marine Diesel Repower Specialists. Before adding Racors you might take a look at his information.

I'll second having a serious read of Tony Athens thoughts.
I just bought a set of filters from him although not yet installed.
Regardless, get his telltale needle vacuum guage for the filters.

Cheap filters may fit the housing, but as noted johnma says the Beta Ratio speaks to efficiency. I buy the Racor elements hoping that Parker Hannifin knows their stuff vs a low price - non speced by PH - Chinese alternative.

But for a new filter setup, I'd go spin ons in a heart beat - 3 stage setup per T Athens and as mentioned by Clark Leighs.

My thinking is inline with Johnma. check out the PDF that is on the racor website. It provides a list of reasons of why not to buy cheap filters. I am all for saving cash were possible but I think you get what you pay for in this case.

I bought a Griffin from Diesel Filters direct out of Texas for a fuel transfer polishing system. More or less a Racor 900 clone. OUTSTANDING customer service. I ordered the wrong adapter and the guy sent me two of the right ones with no money changing hands.

Now that you have your griffin filters. if you wanted to use the racor 900 would it fit ? It if does that may address all the questions. If every is concerned that the Griffin filter might be inferior, you could save $600 on the difference in the housing and buy all Racor filters...then everyone is happy.

Just finished reading Tony outline on filtering and while I agree with his basic idea of starting off with a big filter and working your way down in filter sizes, no where in the article did I see anything about having redundant filters that you could change from one to the other on the fly. The flaw as far as I could see, and I'm telling you I don't claim to know anything here about filtering fuel was. When you are running and one of your inline filters does get a clog, you need to change it. So that engine stops. If you take his line to heart, maybe you put two of his filters in front of racor twin and never need to switch between the two racors.


I must have missed something, but one of his installs he showed close to ten filters, I flat don't have that much real estate for a filter farm or bank to afford it. I guess for my money I'd try and start with a switchable two filter system per engine with a 20mic first and a 10mic in the back up and if I have to switch because I'm picking up crap, change the filter fast and switch back to the 20microm.

If that runs fine for a while, then I'd step down to a 10 in both filters. And if I can get the Racor filter in the Griffin tank, go that route.

If you see a major flaw here please point it out, I love to learn here and not paying my mechanic or the fuel dock.

Thanks for all the input

Not clear what you are replacing but have you considered simply adding an additional Racor to your existing unit, with a 3-way valve to switch between the 2 units? We did this partly because of cost and partly because it was easier to position 2 separate units rather than one larger duplex unit
Plus as indicated previous, it is usually pretty easy to pick up a used Racor on Ebay.

So where did you find your 3 way valves ? I need to pick up 2 new filters to add to the two racor 1000's I have now. Guess my thought was but one completed package and build the other one out of the existing gear I have, if I could do it at a reasonable price.

The Racor filters fit perfectly in the Griffin filter body, that is why I bought it, only one filter size on board. No issues. It is not identical to my 1988 Racor 900 but very, very close. I'm no engineer but I assume they are copying improvements to the 900 series.

In any case, I'm a happy camper.

Interesting discussion, but not being a Racor user I have a question:

Assuming the Racor style filter is your primary filter and you are using 20 mic disposable media filters;

if the China filters are not as efficient as OE Racor filters and are passing contaminates. . . wouldn't you see those contaminates caught in your 2 or 10 mic secondary filters? If that is true, then your secondary filters should be showing blockage?

Has anybody experienced that?
