so lets see if i can paraphrase to see if i get this.........this regulator, (a misnomer if this is correct) actually is allowing pressure to be determined by the amount of returning fuel.
simply letting more fuel go back to the tank keeping the line pressure where you need it. more fuel being returned = less pressure
less fuel being returned = more pressure
hmmm, so with my setup dirt gets into my regulator or a line gets pinched i don't get fuel or have WOT starvation.
with this other set up a pinched return line or
dirt gets into that system and fuel gets sprayed all over my hot engine and i'm engulfed in flames being fed at 140 GPM. wow, i want that i think.
i'm beginning to see the light.....or the flames.....
no, but really i do see the advantages of it until you have an accident and that 1 in 10 chance the return line gets obstructed and fuel comes gushing out your vent tubes and you have a richard pryor situation
