THanks for the reply i may just rig something up like that too , Im not going over 18 psi with the stock tank , if i do now its just getting lean at that boost with the one intank and 72s . I also run a 10 gal cell with C 16 that i can switch to as needed for high boost and timming , the same boost with the big inline it runs richer so i figured id throw the othet intank i have around into the tank Vs putting another cell in the trunk with anothet inline .
