Dude, you are so wrong about me it’s ridiculous. I’ve been running ethanol fuel since it was stuffed down our throats. I’ve spent more time tuning NA and some blown alcohol **** than I care to think about. If you have vapor lock and think it’s ethanol you’d be wrong. BTW, I was running a return line in 1984. Long before any of these other posers jumped on that bandwagon.
There isn’t enough ethanol content even at a full 10%, or even at 50% to cause vapor lock. It’s the pump fuel that does it. It’s the blend of pump fuel.
Just damn. EFI has saved the world.
