I know that this was dealt with before but I can't find the relevant topic(s) now - any recommendations on where to get a new or used oil tank gauge, either mechanical or one of the new fangled electronic ones that give remote radio controlled access from indoors to the oil level? Alternatively, any tips on doing DIY maintenance on one of those mechanical ones in which often gets stuck after a refill and needs a couple of clouts to spring back into action reflecting the new replenished oil level? I'm in Dublin. Thanks.
