This whole thread makes me nervous. Getting soaked in gas, using electrical tools to pump gas, trying to seal a gas leak with electrical tape...
Have you ever seen anyone pour just a small amount of gas on campfire logs before lighting, then throw a match on it. You're looking at 10' of flames from a 1/2 cup of gas and a match. Those small sparks in a power drill could do the same thing. It's the fumes that explode, not the gas itself. You're very lucky you didn't get hurt. |

It's always good when jobs are measured in beers.
 Not sure I'd have had the guts to use the drill, though, there's a lot of joules in 40 gallons of gas. Glad you didn't go boom.

Well it took about 2/12 hrs, quite a few beers and some AC/DC but I got it done. Don't know if it was the thin liquid or the thin hose, but I could seem to move it very fast. I use the same pump to transfer oil in our fish fry trailer and it usually fills a barrel in about 15 min this time of year. I decided against the sender hole because I'm out of cork gasket material an I didn't think the paper gaskets I have would do much good.
The pump leaks so I cranked all the screws tight and wrapped some rubber electrical tape around the seam, helped but did'n eliminate the problem. It was about 5 min of running followed by 10 min of letting the fumes clear. the drill I used moved air from back to front and the exhaust was behind the chuck. The exhaust came out in a radial fashion and with the fan I never smelled fumes behind the drill. I just ran it until the fumes in front got strong and then let the fan clear it out. Hope to have the interior in tomorrow then adjust the valves again and hit the water Thurs even if I just idle to the slip, were expecting rain on Friday, |

I think you're probably right about water contamination. One year with our Merc our last outing was early September, and the following year due to various issues the boat wasn't started until late June, almost ten months later. I had stabilized the gas as usual and the boat started fine. It always runs a little rough while burning off the oil I fogged into it, but then smooths right out (and then I change the plugs). I started stabilizing every drop of fuel that goes into anything other than our road vehicles, because a mechanic friend yelled at me (several times) to quit varnishing up the carbs in my small engines and asking him to fix them. I've had no fuel issues since. I've never heard anyone else say that stabilizer makes their engines run crappy. Some people have told me they saw red deposits in the carb bowl, but I've run the blue marine Sta-Bil (for ethanol-blended gas) and have never heard of deposits with that. Because I can no longer find the lead substitute I prefer, I'm switching to Seafoam as both lead substitute and stabilizer, but that's another story. I never thought siphoning gas out of the tank would be so difficult! Good to know. |

Those gaskets will work for Euro/American gauge styles. Probably get one at auto parts store.... get it taken care of now and worry about the sender later... BTW - ours is American style VDO 240-33 sender.

Half a tank is probably from November, I usually keep it full and add a can when we go out so no exact date. The rest is from the 4th of July. that's why I'm leaning twords water leaking in. I never have gas issues even with my small engines and never use stabilizer because it make stuff run crappy. This is the first time the boat has sat for more than a month since I got it, and it's taken much longer than I was expecting when I started. Unfortunatelly once it got into May I just don't have a lot of time to spend on it, but that stops after Labor Day so hopefully things will be right for the best part of the season.

I purchased this transfer pump to remove 20 gallons of old fuel from my Excel when I purchased it. I removed the floor panel and fuel sender, and used the fuel sender hole to siphon the gas out. It's probably not the quickest tool, but it worked well for $20!

How old is the gas?
I ask because I stabilize every drop I put in my boats, for this very reason. Never had a problem. |

Question for Steve; I know you replaced your sender, did it come with a new seal? I'm not positive I want to mess with trying to reuse the seal that is there. I kinda have a feeling that that may have caused the issue, the floor has been out for months and when it rains I get a puddle on top of the tank. I kept a blue tarp over it for most of the project, but it's rained a few times this summer with the regular cover that leaks.

That's what he has Don. I know they make a smaller diameter one,maybe that one would fit down the fill. I have an old electric fuel pump I use to drain a tank that' I can't use the siphon on you might just have to go that route.

The sender hole is the ticket, it will get you to the bottom of the tank.... And Hollywood, I told you not to call me that anymore!

The jiggler! Like Steve mentioned it might fit through the sending unit hole.

Bass Pro Shop (On-Line) sells a clear hose that has a brass end with ball. You put that brass end into the tank and pull the hose up and down and the gas comes right out. However, your floor tank may be a different situation. These siphon hoses from Bass Pro are very inexpensive.
I hope this helps, Donald |

Already got one, it just 15ft long now. I think the metal piece is hitting the neck on the tank and that's keeping it from working through the fill side. I've been using that since we had to get the new safety top on the cans, I spill more with those than I get in the boat and they're very slow. With the new extension I'll be able to fill the boat while I sit on the roof top deck.

Easier- Brians' almost there..... I would remove the fuel sender after taking up the floor. I use a Super Siphon to fuel the boat from cans cuz it's too hard on my back to suspend the cans while the boat is in the lift.
Super siphon is cheap and works great! You will need a barb and some extra hose to extend it over the hull....but it's your ticket and you'll use it afterward........... |

That's almost what I have set up now, I was using the oil changer vac to prime the hose, but it would get just enough air to break the siphon. I sealed everything with electrical tape, the tiny bit of air seems to be coming from the tank itself. |

It's on the trailer so I can't lift it any higher. I would have been thrown under the jail for spilling that much gas if it was on the lift.
Yeah it's a gas issue. I cleaned out the carb, change the fuel/water seperator and it ran out of a 1gal can without much protesting. Plugs were wet and black and I apparently haven't found an acceptable method for adjusting valves, but other than that it fired right up and ran fine for about 5 min. |

you could get a 20-30 dollar auto parts store cheapo electric gas pump and some hose aligator clip it to your battery and run it out. I had a little navigation error once towing the boat down to reids and got stuck out in the backwoods of pa with no gas in the truck I just pulled the hose of the front of my fuel cell and ran my electric fuel pump and filled up a rubbermaid tote of gas real quick.
But really it takes a couple years to get gas that bad off are you sure its a gas issue? |

Pop the floor panel out, remove rubber hose from barbed fitting, attach section of hose from barbed fitting to pump to drum, pump

Can you lift the boat high enough to siphon it onto the dock?
I would stick with the siphon method. Remove the anti-siphon valve, keep the fill tube capped and pressurize the vent line. Probably still need to manually get it started. |

Been very busy lately and have t had much time to play with my boat. Got some time yesterday an among the things I found was I let the gas sit too long so I've got a 40gal of gas that the motor doesn't want to burn. So I made up an extension for my siphon and got a 55gal drum and went to work, 3 hrs later I'm covered in gas and have managed to remove about 2 gallons. The hose seems to get stuck on the way to the tank through the fill tube, I'd prefer not to cut it because replacing it would be a large undertaking. Next I tried using the line between the tank and the filter and found the anti siphon valve works just fine. Tried using air through the intake to push it out that line and that just pushes it out the vent, got a nice shower from that. The last thing that I haven't tried is using the drill mounted pump to pull it out. Not crazy about that idea since the drill isn't rated for the bildge. I can use a very long hose and, with a fan behind me, stay upwind of any fumes, but it still makes me nervous.
Has anyone successfully siphoned gas out of a belly tank? Just trying to make sure I haven't missed anything before I break out the pump. |
