If it's returnless then from past experience, I'll say forget it, it won't work. I had one on my gs-r, but it had a return line. I put it inline just before the fuel rail, it had a guage, & I used a guage/meter to get it tuned to proper stoich. It wasn't worth the money or time though. Just did it to say that I had. Back then it was a new thing to imports along with CAI's.
