[Mini] fueling issues after converting to EFI solved

What I was wondering most about is why not just put the facet pump
between the tank and the EFI pump.
Possibly with a King filter thingy in between to set a specific pressure.
I gather the facet is between the big tank and the self buitl surge
tank and the EFI is sucking from the surge tank, which the facet pump
makes sure is always full.
So basically you've built your own Filter King thingy :)
BTW, had a look at your building the beast page: quite impressive!
Now go and throw a supercharger on there for those low revs :)
