Water in gas- some questions

[edwardh1]

how/where is the fuel pick up point in the ga tank located? on the bottom? seems oil (and gas) float on water so water will be at the very bottom? is/are fuel pipes located above the bottom?

How much water in relation to its own volume will gas treatment remove? Say - pint bottle of gas treatment - how much water will it take out?

we wonder if tank has water, cause at very low fuel level engine turns over more b4 starting.

Id say fuel pump loosing its prime, though water could be an issue.

I had a cracked sending unit gasket on my trail Jeep once. Picked up some water and the engine would sputter when I sat still on the trail.

I dumped in a couple bottles of Christy's Drygas and went for a drive to burn it up.

The fuel pickup is typically located at the bottom with a screen "sock" over the intake on EFI setups.

go get some Stabil at the auto store, one oz per 5 gallons of gas, worked for me, the ethonol gas forms water in ur tank, u can go to boating store and get the blue bottle of stabill, one oz to 10 gallons of gas, ethonol is killing boat engines too.

I thought it was the other way around...I thought the [10%] ethonol dries up any water that might be around...Florida has been using ethonol for a couple of years now and I have not heard of a single water issue.

But I have heard of boat owners and landscapers complaining about the ethonol destroying their equipment....But not from water.

I used a product called Water-Zorb or something along those lines for a small outboard engine. I bought it at a boating place and it worked very well for water removal.

I'd recommend 2-3 bottles of isopropyl alcohol (it absorbs more water than methanol), added with a fill up of 100% gasoline. See if that helps.

 

[doitmyself]

I think Crownvic4life is on to something. E 10 gas can absorb 40 to 50 times the amount of water that regular gas can. If water is sitting in the tank bottom, phase separation has occurred.

Manufacturers tell us not to run over 10% ethanol in our engines because damage might occur.

I would think twice about adding MORE alcohol. Think about it. You are going to increase the alcohol content above the recommended 10% AND attempt to push more water diluted fuel through your fuel injectors and engine??

 

[mechtech2]

'Heet' and other stuff to get water out of a fuel system is almost obsolete.
The ethanol in the fuel does this, as it is a huge concentration.
What good will a tiny amount more do?

But yes, water will settle. It can still happen today if you suck up some contaminated fuel at a station, or have some massive leak that allows water into the tank.

Drains are uncommon, but take a look.

And finally, who says you have water? Try a fuel filter change.
But it could be all sorts of other things.

I went for the simple, stabil, added a whole bottle and the water problem went away, no popping on the road, no loss of power, over all it was good, 318 dodge , me and my old buggy............................

 

[mechtech2]

Sta Bil doesn't do anything about water in gas.
Like I said earlier, who knows what the actual problem was?

HEET worked well for me.
