Funny how they posted the story about the used fuel pump. I just put together a motor and put on an Aeromotive adjustable regulator that I got with a project I bought. The thing had been sitting for a long time, but what the heck, should be good, right?

Car ran like crap. Buckin and hesitating...piece of crap... Put a fuel pressure guage on it and sure enough, the regulator just wasn't adding fuel. I put on some crusty old Ford regulator and the car runs like a champ now, though with a little less bling...
