Answer 2

You can use epoxy repair kits found at autoparts stores, but on a plastic tank, the life of the repair will be short. And with this size hole, you're on the edge of what can even be temporarily fixed. The answer to your question is that you really need to replace the tank with a new one.

If you can't siphon the gas, you can probably undo the outlet hose and drain the gas into a pan. Needless to say, be very very careful with this, you don't want a fire.

Yeah, a bunch of agencies make epoxies that'll bond to maximum plastics. J-B Weld (commonplace 2 area equipment)sticks to at least something it truly is sparkling and dry. the common bunch of 3M, Loctite, Permatex and Devcon also make speciality adhesives and epoxies for plastics. you should envision out their products at vehicle factors shops or on-line to ascertain that could be utilized on plastic gas tanks and the best thanks to patch holes or splits. some plastics received't settle for adhesives nor epoxies. Ducati has a plastic tank it truly is susceptible to leaking and may want to't be fixed. merely looked at a Haynes guide for a 1997 avert Caravan I used to possess and it says this is plastic gas tank can't be repaired. might want to favor to Google repairing holes in plastic Dakota gas tanks and note what others have performed. If this befell to me, i might want to in all likelihood take a area of thick cork gasket fabric and slip it in over the hollow then retighten the strap with the wish it would get shoved into the hollow and seal it off.

REPLACE, the patches are mostly made for metal tanks that do not flex up to the size of a small hole; not that size. Every-time you smell a gas fume you will be worried if it's leaking. I need you as a driver , more worried about what you doing behind the wheel; then preoccupied about going a little cheep and looking behind you for leaks and fires, or down on the dash as you drive. It's already out from your van--if you sell the van how would you feel if a family lost their lives ;or yours family: because you spent $5.99 rather than $95.00

Answer 5

You should just buy a new tank, But why cant you siphon the gas out of the hole? I would not recommend patching it because it will always be filled with gasoline and through the seasons the temperature changes will make it want to expand and contract and it might not hold up. HOPE THIS HELPS!!
