Just spent a happy few hours fixing our elderly HRM Starflow 50/85, turns out they don’t run when the oil pump is full of gunk. Went looking for the oil filter, turns out there isn’t one. Or a non return valve. Or a fire stop. Or a shut off valve. So, I’ll be sorting that lot out, the only issue I have is the tank is lower than the burner and so when I have fitted the bits I’ll need to draw oil up the pipe to prime the system. The proper hand pumps cost around £100, is there a cheaper alternative? I have a compressor and could make a bung for the tank to push the oil up, I also have an engine oil sucker thing which I could adapt to fit but I don’t know if it has enough suck as it were. Any ideas?
