I would get a regulator that has a return line that will go back to the fuel tank, I do not like a dead head style regulator myself. I used one for my blower application (a dead head regulator) it worked OK, but I think a regulator w/a return line would be a better way to go. My old blower set-up.
BTW, Douglas my friend from Brazil says SPA products are good quality. I had helped Douglas w/his Chevy Opala & for helping him out, he sent me a large SPA blow off valve, what a nice guy Douglas is.
The quality of the B.O.V. looks good, I have not tried it yet.
