Ya, I can definitely do that... Mainly was irritated because I blew the last tank plus this tank as far as accurate FE is concerned...
These were supposed to be my pre-instrumentation baseline tanks...
I was thinking I should look for a better way to do EOC because even 5s between off & on at 60+ mph, I'll lose 0.1mile on the odo. OK, so it'll probably take me less time to cycle between off & on, but that's the kind of thing going through my mind...
I guess due to the fact that I'm a bit old-school, I was uncomfortable leaving the ignition on for a long time without the engine running... I recall learning that the points-based ignition system of older cars didn't always like that. Might not be a problem anymore for the electronic ignition cars...
