The problem with THAT (and there always seems to be a catch to each suggestion) is that the ARF design has the 800ml tank seating precisely behind the firewall with it's stopper sticking through a fitted hole. Of course, I could move it back but then I'd just be creating a new problem of how to route plumbing. What I'm leaning towards at this point is a combination of the ideas suggested here: A 2mm brass tube mounted to the front of the firewall that I would inject fuel into with a syringe.

While I ponder this, I've been making a new set of longer connecting wires for the glow system since current ones are too short to reach the Microsens controller. One by one the problems present themselves and one by one they get solved. Such is RC modeling.
