Default Which pump to remove fuel...and how??

So my boat has twin 50 gallon tanks and I am having issues with gas venting due to ethanol. It's coming out the vents...and I'm up on dry dock. Normally this happens when temps rise to 70+ depending how full the tanks are. It started venting out in 40 degree weather. I have a serious problem here. The gas ruins my imron (or whatever it is).And yes I did treat gas with stabil.

So I need to get a gasoline pump and figure how to actually use it. My thoughts are to unhook the fuel lines at the water separator and pump into 5 gallon feul cans there??(I have tried I cannot stick a hose down fill intake).

Why would the gas come out the vent because of Ethanol gas? I would think something else is going on.

Many threads here if you search

You can get a cheap fuel pump, I believe harbor freight has, or amazon

Where are you going to store all this fuel?

BUT

I would not waste your time in doing that. What does draining fix?

You should do some more troubleshooting and give us some more details if you want input...

Buy an in line auto fuel pump and some fuel line - mount the pump on a piece of wood, power it with a 12v battery on proceed to pump it out.

i used a cheap bait well pump. attached hoses to it and ran the wires a long way away from the gas. pumped the bulb to prime and it worked great. also harbor freight has a 110 v transfer pump for about $50.

Just make sure if you get a transfer pump they are rated for gas and not only water. unless you want a fire. I got a cheap fuel pump from autozone to pump both of my fuel tanks. Used a cheap 5 gallon drum to collect it.

Any electric fuel pump will do. I bought a $25 one off amazon and just hook a hose to it. Make sure you run a ground wire between everything though, as moving gas though pipes can generate static electricity. I set the gas jug on a wet towel and clamped the ground wire to it as well as the gas tank so there was no chance of static.

Yea, this has NOTHING to do with Ethanol, but all to much to do with "I overfilled my tank prior to storage".

Get a pump like this and mount to a piece of wood, wire a switch to a battery.

I run a lawn equipment repair shop. We get fuel tanks that smell like old varnish all the time and constantly have to pump out fuel systems.

i use an old inline frame mount fuel pump from a walker lawn mower. Since @ 2004 walkers have been efi and use a fuel pump that is similar to an efi car.


I have similar set up at home using a holly self priming fuel pump from advanced auto parts.
(Approx 45 bucks but much cheaper on eBay/Amazon)

I have 6 ft of cable with alligator clips to attach to a battery for power.

It also works great for pumping out engine oil too.

Just make sure you have the hoses hooked up securely and the drain hose in your catch container before powering it up.

Hook positive up first then negative. You can put an on/off switch in if you really want saftey.

i use them to pump everything. We heat the shop with waste motor oil, i use it to pull from our 100 gallon storage container. I had to use it to drain the diesel out of my excursion before dropping the 45 gallon fuel tank to clean the pick up. Also came in handy when my step sisters fuel pump crapped out in her explorer with a full tank of gas.

just make sure it's self priming. Many require being mounted below the fuel tank where gravity does the priming. This wont work in most boat applications.

Yeah, I have no idea what's going on but I have no idea why ethanol would be blamed????

Not to go too off-topic, but I'm curious what kind of boat that is... hull looks identical to my old 72 Trojan Sea Raider.

May have fuel in the overflow line,from a overfill that came out thru vent. Find access to that line and remove fuel. As gas expands it is pushing fuel out. Don't fill you fuel tank until fuel comes out vent.

Graingers sells a 12 volt transfer pump. We use them to pump bad gas out of equipment they work great. Also pump pretty fast.

If your vent hoses are correctly installed and are looped higher than the vent fitting on the hull, this shouldn't happen. Follow the line from the tank to the fitting and see what's up.

I think it was just a few days ago this was discussed on another thread about “looping “ the fuel line.
it is not supposed to loop, it’s simply a 180 degree vertical turn in the vent line above the level of the filler.
This prevents any trapping or pooling in the vent line, it needs to be open at all times in order to breathe, and be self draining in the event it takes on fuel, as happens in an overfilling episode.

Doesn't matter if it's looped, as long as it goes up instead of down, so nothing can get trapped in it. Not sure why the vent isn't just at the top of the loop, because if water got in there that high anyways it's getting in the tank. Mine can't loop higher than the filler, as the filler is in the deck.
