Don't poo-poo that airgap design. It must be impossible to get vapor lock with that design.lol, or at least nearly so. The under-hood temp on my car must be close to a million degrees, what with aluminum heads, un-coated TTIs and running a minimum coolant temp of 205*F.My 750DP runs as stable as can be and never boils the gas away on the hottest of days.That is value over and above,pulling to past 7000 from an idle stomp with Zero stall(stick-car).lol
You would almost have to pry that thing out of my cold dead hands.
