Bill, what pressures are you running.
My Snow kit has a similar variable flow as the Alky system but based on MAF sensor voltage.
The max pressure is 140 psi and it uses the small 2 liter reservoir up very quickly.
At least the 110 octane fuel lasts longer even though more expensive.
I get about 5 minutes of full throttle to a fill up of 50/50 mix. Mind you, that'* about all the G-forces this old body can stand at one time.
