Tom, I really would like to run a front tank, but I'm nervous about having any tank/supply up in the front of a street/strip car. I've been thinking of building/installing a tank up front for the strip only, leaving it all empty for normal use, using valves at the injectors to switch from gas coming from the rear tank, then switch to a front tank for the strip. I believe the 91 swill we have here should allow a safe 14 psi with correct tuning and that would be about 1000hp on the street. The front tank would then supply E85, or alcohol for the strip. We just changed away from E85 down here to E55/E54 because of some law about flex fuel crap. My 2000cc injectors should be fine for alcohol at 1200 HP and up. I do have a nice 3 gallon pretty/shiny surge tank I could mount on the firewall. I could use a smaller rear pump to supply fuel from the rear tank, into the surge tank, then use my big pump out of the surge to supply the engine. Then drain the surge thru the engine system to run alcohol with the rear tank, pump, and lines closed off. The return from the regulator bypass can run back to the surge tank in each system. When I'm using the system for the 91 premium I can open the surge return to go back to the rear tank. Just lots of plumbing.
