How to weld/glue/fix cracked outboard engine plastic fuel tank?

[Arthur Garfield]

Really really helpful to post a PHOTO !

That said,1; non gasoline dissolving silcone gasket sealer should last awhile assuming not high vibration area.

2: bubblegum

3;match material super carefully heat both areas to critical state just short of melting then drip onto cracked area.DifFicult without PRIOR EXPERIMENTATION.
4; Convert to external tank.Often just a simple outboard pump hose into a jug attached (coupled into) to fuel input hose will do the trick.If jug ugly enough nobody will steal it.


All the Best
