86 fuel tank removal

[jasoncooperpcola]

I pulled mine with the cap off. I used a chainsaw around the edges and no luck. I was lifting the back of the boat off the trailer. So I tear the front bulkhead out and go under the tank with the chainsaw as far as I could. My saw has a 22" bar. Try lifting again and still lifting the entire boat. So I turn the boat uphill put the plug in and start filling it with water while the back is hanging by the fuel tank. Then I said to hell with it and start driving wedges under the tank. I begin to hear something ripping and panic. Before I could let down on my winch the whole boat dropped onto the trailer and my fuel tank was floating in about six or eight inches of water. Turns out the foam itself ripped apart. Now this is with the cap off and a bulkhead ripped off.

well i having no luck with this fuel tank removal, i broke off the fuel tank outlet, and the fuel tank inlet is slightly crush, the tank area around the inlet flexes, but that's all i get. i dont want to remove cap, or cut any of the stringers of frame. last hope will be to fill tank with water to removal any gas uels and cut tank open :( any another ideals out there.

Maybe mount something to the surface to grip, or even place something beneath the surface. Remove the cap that the wiring connects to. Find a heavy duty steel rod or similar. Tie your strap or chain to it, then slide it inside the tank. You only need to lift one side, then the rest will take care of itself. Good luck.

I have an 85 steplift and considered this myself. I chose to leave it in since I see no reson to pull it. Why are you removing it in the first place? I can understand preventive maintenance, but is there a failing tank issue with these boats I dont know about? Also, your 1 1/2" filler hose looks like mine, would you replace that too or is it ok to have fine exterior stress fractures since its so thick anyway.

How about the possibility of cutting around the top perimeter of the old tank and finding a new tank to fit inside of the old tank.

Wedsday I will try again, this time I will wrap the rope around the fuel inlet and fuel vent, using the eng lift. If that fails, I will try to use the steel pipe in the tank method. I haunt had any luck finding a cable saw to cut under the tank. Since the tank is the original one I don't trust it's integrity unless I have it inspected or replace. I also wish to inspect the area under the tank and the PVC drain line that runs from the two forward wells. Thanks everyone your inputs

if i am not wrong there is some type of belts on the side of the tanks you will need to cut deeper in to those and close to the bottom at the tank as possible
