I bought a Walbro TIA485-2 pump, 450 LPH that will run E-85 and I was going to run it in place of the GSS342 pump, but I would have had to modify the bracket holding the pump, and just decided to use the GSS342 pump for the time being as I have not gotten the new ECU and flex-fuel sensor wired in.
The CR9CFI with the GSS342 seemed to perform just fine with the old Edelbrock XT EFI system, but I'm probably under 500 HP at this altitude.


That's brings the Spectra tank in a different perspective. May go this way...
