2007年3月8日 · I've used "Seal All" on plastic fuel tanks with very good success. It's made especially for sealing gas and oil and can be used on metal tanks. I've used it on a number of other projects including sealing coolant return tanks, ripped seat covers, on and on.

2019年6月30日 · There are various tank sealers, like redkote, kreem, por-15 that you might be able to swish around where the leak is. I doubt these would stick to a plastic tank very well overall, but you might be able to get it to fill the leaky spot. I'm with the prior responses - plastic weld it with a soldering iron. Side note: lots of ventilation if you do.

2010年9月29日 · If you want to repair the tank yourself and do it cheaply then the soldering iron as mentioned in one of the previous posts does a good enough job of melding the crack back together, then take a piece of metal flyscreen and inbed it into the plastic covering the crack, it will inbed by just heating it with the soldering iron tip and pushing it down into the plastic, smooth …

2002年4月7日 · I have recently acquired a Shindaiwa 488 that contained some old fuel, sludge, pond water, and God knows what else. But, I was wondering what the best solvent is to remove the residual crud? Brake Parts cleaner (I'm nervous about melting the plastic tank), Carb Cleaner, Parts Cleaner Solvent...

2019年9月24日 · Anyone know a proven method of plastic tank repair. I have adopted 2 stihl 028 chainsaws where the original owner ran too long of a screw through the AV buffer into the fuel tank. Also wonder what type of cleaner would desolve the old rubber fuel line melted in the tank.

2012年7月2日 · The fuel permeates the plastic of the fuel tank and will cause the eventual failure of the bond. The only way to repair it is to either replace the tank or weld the plastic. I use a 1500 watt heat gun to preheat the area and a low wattage soldering iron (33watt, with a rheostat to adjust the heat) to weld the two surfaces back together.

2009年4月25日 · You can fatten up the tubing by using like a small barb from a in tank fuel filter or some weed eaters tygon fuel lines they use a small barb and a flat plastic washer to slide down the tubing and over the barb on the outside of the tank to hold the barb and tubing in place but most generally the flat plastic washer is not needed to secure a tight fitting line in place if the …

2009年1月22日 · For a plastic fuel tank, I would first try fresh E10 with a little Sta-Bil and a good slug of seafoam mixed in. This gives you a reasonably benign mix of ethanol, naptha, gasoline and other "petroleum distillates" to dissolve the crud.

2008年2月26日 · To get JB Weld to hold the metal surfaces must be completely oil free, drain the tank and wash it out with something like naptha to get rid of the oil in the tank, sand the metal clean and then clean well with acetone or brake cleaner, let dry and then apply JB weld, even better if the crack or joint can be grooved to allow a little more surface area to be contacted …

2012年2月21日 · Not in my case. It was an MS025. I cut off the remaining stub with a Dremel tool and drilled the plastic tank with a brad point bit to get a smooth hole. The threaded portion of the barb does not need to go deep into the fuel tank - cut it off if it is too long. Look for a small diameter thread if clearance is an issue.
