Do I need this

[skidoo29]

Okay heres the question

I am running a 1990 2.4l bridgeport efi, I have a water seperator.

what I want to know is does this motor require that I need a water seperator?
Are there any advantages to keeping it/ or getting rid of it?

I am asking because I have got everything else out of the hst and now would be the time to take whatever I don't need out.

thanks in advance.

when I run my drag or efi motors. (Ihave it set up so the other pump starts if my fuel pressure drops below a certain point.) When using pump gas last year I drained water out of each filter about every month. pump gas is ****. I'd use it.

Capt

you run it before the fuel pump, right now it is hooked up after. it goes from the tank to the fuel pump to the seperator to the the motor, does it matter which way it runs, or are you just trying to get anything out before it hits the pump

I lost a very good running 260 last spring due to crap getting in the pump. Some said I would have a problem with them before the pumps, but my drag and Bp ran fine and show no sign of pressure drop. I run a couple BG filters after the pumps too.

How often do you change the filter that seperates water?
Do you know how small the filter is in microns?

[Capt.Insane-o]

I'm not sure on the micron for the water seperator, but it has to be damn tiny, my BG filters are 4 micron if I remember correctly I replace them now every two months if using pump gas. With Vp out of a drum I have never had a water problem. In Michigan, corn alcohol is used, that is where the problem comes from.

A filter is a hell of alot cheaper than a rebuild which is what you'll need if you run water thru your motor.

Water will not carry the oil as the fuel does and you WILL
be rebuilding soon there after.

Keep a $6.00 filter handy.
How often you have to change it varies.
But at least every 6 months is a good practice.

As much as these parts are it would be a shame to lose a
motor trying to save $ 12.00 a year.

P.S. If you pour the filter contents on concrete ( oh I didn't
say that ) If water is present it will puddle up while the fuel
disapates across the surface.

And know you can't just empty them.
The element absorbes water so when you empty it
you are just pouring out the excess that the element
could not absorb.

I hope this answers your question!

I think the paper element water seperators have a something coating on them that blocks the passage of water, then you drain it out.
I assumed over time this wore out or something and didn't block the water anymore.
One of the sites I was surfing at mentioned thats how thier filter stopped the water. It also said it won't stop water if there is alcohol in the fuel. Again an assumption but I think this is because it's locked up with the alchol. Probably isn't a big problem if alchol is grabbing it and carrying it away to be burned. It's only going to grab so much though, don't know it the rest would be stopped.

Was going back and forth on this, I think I'll run one.

I've always run the seperators ahead of the pump also. One of Merc's old diagrams shows the return line going into the second inlet port on the seperator ahead of the pump.

Water in gas is a huge problem in new england. I drain out half full water seperators all the time. Techno to my knowledge a water seperator works on the principal that water will settle at the bottom of any container with gas oil and water(gravity at work) . The seperator just gives it a place to collect. You can check this by dumping your full water seperator into a clear plastic bottle and wait a minute or two for the water to settle. The filter medium just strains out the junk. there is a filter that we use quite a bit its made by Racor and it fits into a standard spin on oil filter style water seperator. The bottom of the filter has a clear glass area with a petcock. If water is present you can just open the petcock and drain off the water. With plastic tanks or clean aluminum tanks these filters will go a long way.

WATER = BAD
FUEL = GOOD

SEPERATION MEANS THAT EVIL MR WATER CAN NO LONGER INTERMINGLE WITH YOUR PRESIOUC HYDROCARBONS.THEREFORE IT WILL BE KEPT FROM REACHING YOUR ENGINE.

At best water will cause your motor to temporarily stop!!

At worst water will cause your motor to permanently stop!!


In a multi cylinder engine with multipal carburetors water usually enters one float bowl first. Because water is heavier than fuel it will not pass thru the carburetor. This Prevents fuel (at least 50% of your pistons coolant) and oil from reaching your pistons rods crank ect.

As the motor seems only a little down on power the other cylinders continue to fire while draging the starved ones along without any fuel or lube they usually fail causing catastrophic dammage to the engines internals.

A lot of water usually is less harmful beacause its presence is obvious.

Small amounts of water can sometimes go unnoticed causing greater dammage.

Personaly I install water seperators on all boats that I rigg and every time I am involved with fuel system repairs.

Their large volume (trapping lots of junk before limiting flow) is also handy in situations where the tank or lines are known to have had a corrosion or rust problem.

The paper filter water separators are pretty simple: Scotchgard waterproofing is sprayed on the paper. Gas goes thru it, water doesn't.

The Racor is a nice filter, though a bit bulky. It works by centrifuging the water out. Incoming fuel spins outward around the outside of that inverted funnel shaped fixture inside the bowl; heavier water flies more to the outside and settles to the bottom ... the lighter gasoline can more easily make the U-Turn to the center outlet inside the funnel and get out.

Pretty cool, huh?
