The first thing you should understand is that direct-port, constant-flow fuel-injection—Hilborns, En-derles, Crowers, whatever—were never designed, nor intended, to be run on the street. All of these ...

This overview illustration will help you place many of the different sensors used in a multipoint fuel-injection (MPFI) engine such as a 5.0L Ford or GM tuned-port-injection (TPI) 305 or 350. One ...
