I want to source an in-line one-way valve suitable for diesel, to prevent flow back to the tank when the ignition is off. This can either be a conventional non-return valve suitable for approx 5mm bore rubber pipe (preferred) or a 12 volt solenoid operated valve, open when ignition on/activated. I know these were used on a Lotus at some time (presumably petrol - but I guess diesel is less aggressive) and possibly many other cars as well..
Can anyone tell me where I might get one of these please ?
Thanks, Nick
