need help with fuel cell

I've been thinking about installing a 5 gal fuel cell in the trunk for c16 fuel only...I want to be able to switch between the the two tanks.... I'll be combining two bins into one for my tecIIIr... For boost under 15psi, it will be tuned for 91 octane and for boost over 16 psi, it will be tuned for the c16 fuel..

I want to be able to switch tanks back and forth... I will build a time delay circuit for the return line for it to have a 5 to 10 second delay to allow the fuel in the lines to return to the tanks that it currently is switched on to... that way the two fuels won't mix together, atleast what's in the fuel lines once I switch it over...

I know how to do it, but I need help as to what hardware is available and where I can get it...

Just imagine being able to go from low boost (14psi), to high boost 20-25 psi at the flip of a switch...

Hmmmmm, sounds vaugely familiar, lol.

OEM Ford truck duel tank switching system might be worth a looksie, and its cheap. As for the delay for the return, your on your own because I have no clue.

You can't easily switch from unleaded to C16. You really have to flush all the lines clean. Probably not a very good idea.

hmmm, no problems switch from 93 unleaded to 100LL in my car. Leaded fuel isn't anymore corrosive than regular, alcohols like methanol are though.
