Finally .02 from someone who tried it!!! Respect !!! Do you think my idea of sniper kit for efi that requires 43 psi for fuel side will work with a adjustable regulator before the vaporizer ? just as you did but regulating it to 40-45 psi to solnoid will work to help with steady fuel pressure , not tank pressure ??? Do you think that will make it tunable ? I don't want a extra tank with fuel.. when I running 110 oc fuel already but I'm shooting for 35-50hp boost on a toy. not a big motor. Sorry to hijack the thread and hope the info helps us both!!!
