I have a massive problem with my autococker. First of all it was leaking air so this was the problem I was trying to resolve then when I was trying to take the front block off one of the nipples/barbs for one of the hoses snapped in the hose. I now need a replacement and I will need to find the air leak as it was not leaking from the front block but in the main body behind the block. I do t have much experience fixing autocockers and this was my old marker I just managed to dig out of my dad's loft where it's been stored for years. Can anyone help?
