Amigos. Absolute disaster and I need the collective wisdom off Arrse to rescue me. Moving house with a Transit van. I may have had problems with vehicles from the same source in the past. Last words to me were "Detonator, dont fcuk it, we want it back fit on Monday". Piece of pi5s methinks. Until I fill the fcuker up with diesel, when its petrol. Cue four hours of innefective syphoning. My question is this: Tank pretty empty. Its only Â£7 worth of diesel so 5 1/2 litres ish. If I just fill the fcuker to the brim with unleaded will it water it down enough to work fine? I cant get a garage to fix the problem as I still need to move, tommorow! Please make me very grateful!
