[T3] Bad day at the (FI) office

Wed Mar 16 04:18:42 PDT 2016

On that what is your cost for the prime kit you sell?
This could be useful even with a Megasquirt. I noted it need more this week before it got all the heat soak vapers out of the line after sitting all day. I still have yet to find a setting that will extent the time of the key on prime in the Megasquirt.
