Guys, I'm trying to figure out where and how to attach the sender of my electic autometer FP gauge.. The directions say to not attach it directly to the fuel rail, but I don't see how that could be a problem. Anyhow, shouldn't I need a female to male connector to attach on the end of the fuel rail, past the regulator? I did a search and found other people doing this, but no one mentioned what size (earl's or aeroquip) is needed.. Thanks for the help - Josh
