Happy Birthday. I just noticed.

Thank you Ian, I do use Esso or Shell E5 only. Last year I had to replace the metering unit drive seal with a new Viton seal and the previous year the diaphragm seal with a viton item. Due to lack of use I've had pumps seizing up with varnish due to fuel going off. New pump, fresh fuel and if the problem is still there it's plugs, injectors,timing and so on..... Ken.

Thanks for your input, are your replies based on experience of problems directly caused by stale fuel? It's wishful thinking I suppose but I was hoping somebody would say they had the same symptoms which was cured by draining and refilling the tank with fresh petrol. Thanks Ken

Can stale E5 be the sole cause of very rough running? ( been idle for months with the occasional start up and run to temp) 1970 Tr6 with lucas pump (weeping) Less than a 1/4 tank of 6 month old E5 so not enough fuel to add my fuel stabiliser. It was fine till a few weeks ago, now it sound horrible, it even has the occasional back fire. The PI leads all have a pulse. I need to remove the pump so I'm reluctant to add fresh fuel. Is it just the petrol? Thanks Ken.
