A lot of the same consensus, if you wanna do it once and have the fuel system ready for more power, just go in tank.
On the other hand, jhein, who started that thread, ended up with a RobbMC mech pump and that seemed to solve his fuel issues. He estimated that he’s around 500 horse.
I’m leaning towards that route myself, I guessing I’ll have ~450 horse when my 433 gets done. But I dig simplicity, mech fuel pump, qjet and points dizzy is my kinda setup.
