Flex Fuel.
Is it really worth all the money going to top feed injectors, fuel rails, surge tank or can it still be done with stock side feed and just off the pump in tank?
that said what size fuel pump should i be using if we wanna target say 28-30psi on ethanol?
My injectors are too small (850cc) so probably on 1300cc
FP regulator needed or stocko be fine?
Anyone gimme a spill on there flex systems or experiences?
Seems my fuel pumps gotten a bit noisy lately and i think its on its way out. if im replacing parts of the fuel system ill slowly shift it towards e85 compatible system
