Did you need to replace the gasket under the cover you removed?
I detail this a bit more here:

http://www.trawlerforum.com/forums/s...nks-34481.html

It didn't take long. I used a 1/2" long socket. The bolts were tight but not excessively so. Most of the time was spent cleaning up the excessive amount of pipe joint compound the PO had used as well as the aluminum port plate. BTW, it seems this PJC seemed to cause some "oxidation" of the aluminum, even some small amount of poultice corrosion. I reused the gasket after cleaning it up. In one of his articles, Steve D'Antonio indicated the use of silicone "grease" was appropriate on the gasket, so I used that.

I mention in the thread above that I intend to move the ESI fuel polish system to the inverter side of the AC panel so I can use it while underway. I contend that you need "agitation" or "movement" of the fuel in the tanks to free up the asphaltens for filtering by the system. Running it whilst still at the dock is not that effective. The PO installed it so I may as well use it. right now it's mostly use to rebalance the fuel in the tanks to improve trim of the boat.

Those are pretty nicely made tanks, as they are welded inside. Many or most aluminum tanks are welded on the outside seam, which leaves a vulnerable seam inside.

Injectors are out for rebuild!

You guys are right, I wonít pay to have the tanks coated until the boat is officially mine.

Iíve got some reading to do. I have no idea what a a Racor is

Did they just paint the engines? What a difference from your fist post in this thread. They look great now.

Being an expert on somethings, doesn't make you an expert on everything.

Parker Hannifin, the parent company or Racor is an expert of fuel, air, and may other forms of filtration. Equipment manufacturers go to them to solve problems and manufacture solutions. Don't think you will find Tony at that level.

I have read Tony's article on fuel fitration before. IMO, not having a bowl in the bottom of your first separator is like giving up engine gauges at the helm for idiot lights. Without the bowl, you have to wait for fuel problems to reach critical mass. With the bowl, engine checks allow you to see fuel problems developing before they reach critical mass.

Check the header tank pressure caps. Iíd replace them if they were just painted over from the looks of the first photo. What did your surveyor say?

I certainly donít think that Racors are the ďbestĒ filters out there. My point a few posts above was that with a dual Racors as your primary filtration you have all the tools you need to be able to ensure that your engine gets clean fuel. The problem is that the operator actually has to use them correctly. That means checking them.

I donít check mine that often, usually about every 2-3 days of using the boat. However, Iíve never had any debri or water in the Racors. Last summer I completely disassembled and cleaned them out when I added a stop-cock to the bottom of each. After 7 years of use, about 1000 engine hours, I only got a very slight film off the inside of the filter housing when wiped down with a shop towel. The point is that Iíve got very clean fuel. For Steve, I would expect the fuel to have some crud in it, even after the tanks are cleaned and new fuel is added. Checking and changing filters as needed would be something I would anticipate and a dual Racor system is convenient for that.

I have read Tonyís article a few times over the past 3 years. I think in many ways it makes a lot of sense. Keep in mind that he recommends draining a fuel sample from the bottom of the separator before running the engine. When done, this is better than trying to visually inspect a Racor. One of the reasons I put stop-cocks on my Racors. Easy to drain some fuel and see if there is any water there that would be missed trying to see in the bowl with the metal flame shield around it.

Since I have clean fuel and the boat came with a dual Racor system, there is no reason for me to need to change. However, if I was consistently getting fuel contamination or had questionable tanks, then I might consider adding a bulk filter/separator before the Racors. OTOH, I likely would just check the Racors more frequently and change the filters more often. They are certainly easy to change.

With any filter, it all comes down to the filter media. The can that it's in is just a can. I've never seen anything to suggest that Racor's media is better or worse than its competitors.

Racor is a fuel filter system by Parker Hannifin. The most popular is the Turbine Series.

As you can see not all agree Racor is the best. But all of us agree if the filter / separator, no matter the manufacturer, is not properly used and maintained it will fail.

Clean your tanks, keep 'em clean, maintain your filter / separator or face the consequences.

The problem with the Racor system is the ABYC recommendation for the heat shield. It makes it pretty much impossible to see if you have water in it. The PO put petcocks on them but he gummed them up with pipe joint compound. I drain them when I replace the filters by siphoning out the fuel and tossing it in the disposal tank.

Replacing the petcocks isnít too difficult. Maybe replace each as you change the filters. I know what you mean about the heat shield. I considered removing them when I disassembled and cleaned the housings, but chickened out.

Like most TF discussions...... best...... is an elusive term.

Many feel that their boat should not only exceed USCG standards, but up to date ABYC standards.....and just to be safe, NASA standards.

Just like the doctor that graduated at the bottom of his class....he is still a doctor and if you need one.....he just might do fine...as not every situation requires the best.

How many sea miles have been traversed with Racor turbine filters? Just about every commercial boat I have run had them. So yeah....more common but not the best?.... does it matter if they do the job?

In my own ignorant opinion, a Dual Racor system is quite good as long as it is used properly. Sure the tanks should be cleaned and the fuel should be externally filtered before being used (or given away and fresh fuel be used after the tanks are cleaned). I would still expect some crud to get kicked up at first.

Running a dual Racor on one filter and having a vacuum gauge installed means you should be able to avoid any problems. However, the operator has to use it properly. I’d be checking the bowl on the active filter hourly at first looking for water and vacuum rise. If so, switch to the other filter and drain and change the first. Keep doing this until the problems don’t recur. A case of filters will do wonders for staying out of trouble.
Very well said.
That's also been my experience.

It's no big deal to open inspection ports and clean up remaining crud.
I used cheap mops to wipe walls and shop vac to suck up whatever is left.

I have the heat shields on my dual Racor 1000. Find it quite easy to see the contents of the bowls with a bright LED flashlight aimed from behind toward the bottom of the bowl. In the USA fuel is dyed red, so there would be an even more pronounced difference between fuel and water.

Find a bright LED flashlight indispensable for engine room checks, especially underway.

Visual inspection is somewhat overrated in my opinion concerning the Racor's and definitely not worth the trade off of the mess they create when changing, especially underway. If you have vacuum gauges with a drag needle and solid filters that have drains, it's a simple process to open and drain a few drops into a tupperware container and examine for water and crud. I removed my racor and replaced with filter heads and run solid spin on filters now with drains.

No mess in changing the racor. Just drain the housing through the petcock in the bottom of the bowl before removing the element.

If you did periodic checks of the separator bowl while underway, you wouldn't be trying to change a filter underway.

Drawing fuel samples while underway is unrealistic. While it probably isn't necessary running 8 hours or less, if you're doing overnight trips or multiple day runs up the coast, knowing fuel filtration status becomes more important.
