Hello again. I'm not sure if I follow your issue but I noticed this online. Perhaps, it's the tank. Do you have a link to the Spectra Tank? I'm still considering EFI too... waiting for you to work out the bugs!

I was getting Spectre and Spectra mixed up. I see the tanks now.....
I was considering these as a predecessor project to the EFI... not sure if they're worth it or necessary...
