    There used to be a product sold for repairing leaky vintage/classic motorcycle tanks which you poured into the empty tank, once you had removed it. You them swished it around until it had coated the inside, poured off the excess and left it to cure.

    That seems just what the POR-15 sealer mentioned in the link by digs does.

  2. Classic Car world has some nice pointers: https://classicsworld.co.uk/guides/e10-fuel-a-classic-owners-guide/

     

    Key snippet:

    In addition to running issues caused by the mixture-leaning effect of E10, information issued by the Federation of British Historic Vehicle Clubs (FBHVC) explains that the increased acidity, conductivity and inorganic chloride content of ethanol in E10 can cause corrosion and tarnishing of metal components. But while this can be controlled effectively by corrosion inhibitor additives, the same cannot yet be said for its compatibility with elastomers such as seals, flexible pipes and other unsuitable gasket materials.

    New E10 fuel provides a greater threat to rubber fuel hoses.

    Ethanol molecules are smaller and more polar than conventional petrol components, meaning there is a lower energy barrier for them to diffuse into elastomer materials. These materials will swell and soften, weakening the elastomer structure, and on drying out they can shrink and crack resulting in fuel leaks.

     

    As yet, the FBHVC is not aware of, or has tested, any additives that claim complete fuel system protection with respect to elastomer and gasket materials when E10 is used. While there hasn’t been an endemic of failures in other territories where E10 is already established, the FHBVC sensibly recommends that such materials are replaced with ethanol compatible materials before using E10.

     

    The good news there is that uprated parts are available. For example, Burlen Fuel Systems has worked with knowledgeable suppliers over the last 15 years to introduce upgraded rubber with Viton content for parts like carb needle valve tips, diaphragms and jet seals, along with cellular foam carb floats and upgraded needle material. It also buys all its fuel hose from Goodrich as it knows it has been properly tested.

  3. Different bulbs have different heating characteristics, light units are designed with this in mind. This is why you cannot fit light bulbs of a different kind to what it was designed for most of the time. Some LED bulbs have caused car fires.

     

    In any case, contact your insurer if you want to drive around in a car that isn't road legal. Maybe their cover will be valid. Probably not. You'll only find out when someone without insurance hits you, and your insurance won't pay out. :shrug:

    Well it passed the MOT no problem?

    Passing an MOT does NOT mean your car is road legal, nor that you haven't violated any terms of your insurance. The MOT is specifically disallowed from doing any "destructive" tests, i.e. anything that involves unscrewing, unplugging, taking apart. The DVSA can do a road side inspection and find your lights are not legal, therefore your car isn't road legal, therefore you're effectively driving without insurance.
