I plan to ask Allmakes / Britpart for confirmation of E10 compatibility of the standard mechanical lift pump, but given its price, even if it only lasts a year, its probably cheaper than the additional cost of "super" fuel. I currently have a test of an Allmakes Zenith overhaul kit and a Bearmach Solex overhaul kit with all the rubber components soaking in E10 petrol. They have been sitting like this for the last three months with only the occasional agitation. So far, I haven't seen any deterioration. Admittedly its not an ideal test as the diaphragms are not being worked, but should be a good indicator.
In my view, from what I've seen so far, this is probably an unfounded concern. Clearly its something we need to watch out for and in particular with failure of the joiner hose to carburettors (especially those ones with filters in line over the hot exhaust). If a lift pump diaphragm fails, there is a risk of petrol getting into the engine oil. A daily level check will show that anyway.
I think for the classic car market, the biggest issue with modern fuels is how they behave when not being used. If the average mileage of a classic car in the UK is apparently 1500 miles, then an awful lot of vehicles are sitting about with deteriorating fuel in their systems. A fuel stabiliser will help of course, but people need to be aware that ethanol absorbs water. This could encourage more unwanted water collecting in unhelpful areas of fuel systems potentially causing corrosion and other damage. The point being that if these vehicles are not being used and are sitting in storage, they must either have the fuel system completely drained or run regularly with fresh fuel. Those of us regularly using our vehicle probably don't need to be concerned.
I'd be more worried about running an elderly fuel injection system such as an EFi Classic Range Rover. There are a lot of small hoses, link pipes, vacuum hoses, regulators, pumps, injectors etc. to fail. I remember that LR used to do a special fuel pump for ethanol enriched markets (Brazil) in the 1980s and 1990s to avoid this problem. The pumps were very expensive with increased stainless steel components to stop internal corrosion.
