i ran e40 with stock pump for almost 2 years with no issues
main thing is to log and check your lpfp , it shouldnt be dipping under 50 psi, its ok if it dips for a split second and it comes back up, but if it stays below 50psi then it cant handle that much e85 in the tank

Ok thanks, I'm really only interested for days I go at drags.
Another question just to make sure, since our fuel tank is 60 liters, that would mean a 30% mix of E85 would be pump 18 liters of E85 and fill rest of tank up with regular fuel?
For the regular fuel what octane is needed, normal premium which would be 91?
I'll make sure to log lpfp additionally to corrections to see how well it handles.
EDIT: Should I instead run V8 labeled E30. Does E30 mean 30% ethanol or a 30% of pure ethanol and rest of fuel OR 30% of E85 mixed with 70%regular gas
