Re: did someone pee in my racor?

But if someone pees in it, you can expect it to be yellow.

Nobody has mentioned it but the water will appear clear compared to the color of your fuel...If you want to see what you will be looking for... pour some fuel into a glass and add a little will separate out...

Check for water every couple of dozen hours of operation. Do the check before you start your engine and it will have plenty of time to separate out and fall to the bottom.
Once it's done that you'll see a clear demarcation between the fuel and the water.

All you really have to do is make sure water doesn't fill the bowl - that would make fuel passage / filtering impossible, what I'm saying is when you drain you don't have to get every last drop, this isn't Maxwell house coffee.

Here's the good news, by opening up your system you've made possible another lesson in diesel maintenance, bleeding the fuel lines.

The clear bowl comes in handy for this too - make sure you never see any bubbles in it.

Best book on diesel engines and boating I've read (some of) is:
It is a bit technical but if you really want to learn about your engine and boat's systems this is the book that will save you a lot of money in repair bills.

Re: did someone pee in my racor?


when motoring, where do you like to run your engine? what is your typical water temp at that cruising rpm?

Re: did someone pee in my racor?

Make sure you seal the racor properly when you put it back together - you need the fuel system to be completely airtight.

I believe the clear bowl on the racor allows you to see water (it will separate from diesel and appear distinct in colour). This sinks in diesel so you can bleed it out with the drain at the bottom. I say I believe as in four years of running a boat with a racor I never actually had to do this...

Great engine.. we've had the same in our last two boats. The Bosch injector pump is pretty good at self bleeding as long as it you get the fuel to it.

Fuel in your sample looks clean..

Re: did someone pee in my racor?

thanks guys. i thought any liquid in the bowl was water. the bowl was full and that made it hard to decipher what the liquid was. good info on the follow up procedure as well, thanks. and yes, that would be road diesel. the previous owners doing.

not knowing the mechanics of the thing, this description from the parker website confuses me. makes it seem like the only thing that should be in the bowl are contaminants.

Stage One: Separation
As fuel enters the filter assembly, it moves through the centrifuge and spins off large solids and water droplets which fall to the bottom of the collection bowl.

Stage Two: Coalescing
Small water droplets bead-up on the surface of the conical baffle and cartridge element. When heavy enough, they too fall to the bottom of the bowl.

Stage Three: Filtration
Proprietary Aquabloc® cartridge elements repel water and remove contaminants from fuel down to two micron (nominal). They are waterproof and effective longer then water absorbing elements.
