So I'm kind of chicken to try E10 myself even tho my engine is out in the open. My plan is to run a blend of E10 and 100LL, which I figure will mitigate the bad effects of both (half the amount of ethanol and half the amount of lead) as well as keep the vapour pressure down. I'll still go to the recommended maint. intervals for when running leaded gas tho...

As someone else stated, the 914 fuel return line needs to have low resistance (i.e. - unrestricted) per the 914 Installation Manual. Restricting the return line will flood your carbs and likely result in a fuel spill. I made the mistake of briefly pinching off the return line with both pumps running once. Not smart. The fuel pressure test we were conducting quickly turned into a test of the carb/airbox drain lines. BTW, our return line connects to a "T" on the suction side of the fuel pumps instead of returning to the tank.
