How to repair my Spear and Jackson petrol hedge trimmer fuel supply?
Have replaced the primer bubble because it was rotten. the assembly then leaked and didn't pump. Re-fitted it and now it only pumps air. Have replaced the fuel line into the tank, thinking I may have damaged it, still it doesn't work.
Is it possible you have the next fuel hoses mixed up. There is a long hose and a short hose. Flow and return. It may be possible you have the short hose on the flow side hence drawing air
