jus get a new tank m8 they arnt expencive frm scrap yard or have a look for a "breaking typh" add on ebay
gotta agree gunna be more hassle if you just bodge it together? new tank there only cheap most peopel dont want/need em :good:
on metal i use chemical metal that might work on plastic or you could use a larger bolt then the hole with a bit of sealer on it bit bodgery but could work. take it some dick half inched your fuel
The guys are right, you really shoudn't repair a petrol tank if you can get another one, a fire under your bum would not be nice. If you were really stuck somewhere away from home and needed an urgent repair then a product called "Q bond" is excellent on most plastics, not cheap but very good.
