Sure but from where? bench was dry. Toolboxes were all dry. And it was stored inside all winter.

So please explain how I picked up a pint of water in a 6 gal plastic can standing upright holding about .5gal of fuel that was to be used in a snowblower!

I can even forward a picture of the container with the gas and water still mixed if you like.

ethanol separation. part of the fuel tank testing for OPEI is to let the ethanol separate out for 14 days, drop the temp to freezing, then impact the tank.

Re: particles in fuel water seperator

Robeward, if your motor is still running like carp even after running on a stand alone tank, crud has gotten into your carb.

at this point, time to clean the carb.

regarding where the carp is coming from, as I stated prior - much of the stuff is pumped in when you fill the tank.

Way beyond my undertstanding of chemistry and OPEI testing but a pint of water to a .5gl of fuel sure seems excessive to me.

Bruce, that whould have to be one hell of a leak!

Re: particles in fuel water seperator

I just went thru this with a 40 gallon tank my best guess the tank had 15 gals of gas. Filled it up and i was startled at how little it took and when i fired it up it ran well for 30 seconds and then nothing...Of course the fuel filter was full of water i was dumb founded until i remebered i had the sender out eailer in the year and the tank was exposed for about 4 day's. I simply but the boat on a 30 degree angle for 24 hour's, took a garden hose that was filled with water placed it in the bottom and gravity siphoned about 8 gallon's of pure water out of the bottom.

When the gas started flowing it took another two gallon's for a clear gas flow...took of the gas line off the tbi and cranked her over till the gas flowed. hooked thing back up filled it up and put three can of heat in the tank. Two weeks later and things are fine...Yes alcohol will attract moisture right out the air there is no question of that...Just ask anyone who has bulk plant it's part of the deal.

Re: particles in fuel water seperator

wow getting tense here. i took the carb off last sat and sent to a guy to get them cleaned. i agree that is the issue. just trying to convince myself i know why it happened so i can prevent in future.

doesn't seem like water getting through my filter would clog a carb. seems like it would have to be tied to the large amount of trash in the fuel. while the fuel water separator was likely at its limit i do not feel that i have a big water problem. i have already siphoned out 5 gallons and found no water.

carb goes back on tomorrow. i have a fuel pump. just going to pick up an extra mount for a fuel/water separator and do a little self polishing before cranking her up. i will let y

Re: particles in fuel water seperator

last question. i use the sierra 18-7866. it is solid metal with no clear bowl since this is an i/o application.

if i remove that filter after a trip, dump it out, don't find water, is it ok to continue to use that filter? my replacement cycle will likely be every 2-3 offshore trips where we will burn 60-80 gallons regardless of status of filter.

No, you never reuse a filter. When you dump a filter some of the trapped particles could flow out and rest on the outlet side of the filter.

that is what i was thinking also. it just seems like a constant gamble with the solid metal ones. is the fuel i just bought clean or dirty? is that bowl full and about to start sending water to my engine? i guess no more than they cost i will just change every couple trips and hope for the best. about all i can do

So far you have found NO water. There is no real reason to expect to find any more.
Instead of constantly replacing Good Filters. Take a spare or two along.
Don't replace until you suspect there might be a problem.

yes there was water with the original picture attached along with all the trash so i do still have dirty fuel. i will definitely be replacing every trip until i see a clean filter. just trying to decide what a good interval after that is.

you say don't replace until i suspect something and that is my question. without the clear bowl the only way i will know is when my engine starts acting up and i don't wont to be back in this position.

Even with the clear bowl, your not going to see anything beside water.

I use a vacuum gauge to determine filter condition. I get upwards of 200 hours between filter changes.

Maybe once you have a clean fuel system install an inline filter before the separator. Maybe a large clear plastic one. You're checking/cleaning your carb filter too? Providing it's not injected, I haven't read all the posts....

It is an I/O and the Plastic OB filters are not recommended for use below decks because they will melt in a fire.

But I have done it at times for troubleshooting purposes.
A good inexpensive pre-filter for the big expensive screw on filters.

our carb does not have a filter built in. at the time our only filter was the fuel/water. we are installing an inline filter now, at least until we get the trash gone. the carb is an edlebrock 1409

Re: particles in fuel water seperator

Robeward when you siphoned out did you use the tank fuel pickup and most importantly did you raise the front of the boat way up and give it a good old shake before hand?
By 'way' up I mean tilting the drive and raising the front until something at the rear is touching the ground.
You need to concentrate any water to the back of the tank where the pickup is located.

i raised the jack the front as high as it would go. the jack was also on two bricks for extra height. it wasn't as high as i would of liked but the grade was definitely to the rear. if there was a discernible amount of water it wold have made it to the back.

can't really speak on how the baffles affected this as i am not sure how the tank is made.

i removed the sending unit and stuck a pipe in the far rear corners. our tank does not have a screen on the pickup. it is just a pipe stuck down i tank. i did not give the boat a shake. it had been sitting for a week so i figured if there was anything to collect it would have

Re: particles in fuel water seperator

Ayuh,.... I happened to have the housin' for a Mack 2ndary fuel filter kickin' 'round, so I bought the filter,...
I think it's 5 or 10 micron, 'n holds 'bout a gallon,...

If ya want,... Just pump the 1st 5 or 10 gallons out, 'n into whatever yer throwin' it away in,...
After that, there's no reason to pump off into the barrel,..
Right back into the tank, still strains the fuel, through the filter,...

Mine's alot simpler than that video,..
My pump is like that one, only I put long wires, 'n spring clips on the ends, no switch, just hook it to power,...
No pretty board mount either,...
Just a pump, with hooks, a filter housin' with hooks, 'n hoses in between,...

you can always remove the sending unit and put a hand pump to the bottom of the tank and see what comes out...I am sure there is more where that came from

Cool. As you know that carb is a 600cfm marine. I'm running a Edel 1406 in my Rod.

I'm using a inline filter like this, which can be cleaned, it's glass:
Moeller Clear View In-Line Fuel Filter

I read the fine print and they don't recommend it for inboards.... Maybe it can shatter in general(I suppose) or high temps. If that's the case, I would be abandoning ship before that happened.....

Re: particles in fuel water seperator

So Robeward have you ever found any water at all either in the tank or in the filter?
My next step would be to cut the old filter open and look for signs of rust even though it is fairly new.
