I've seen some anodized aluminum fuel rails for sale before on e-bay for 914's. They had a fuel pressure guage attached. Did anybody else see these? I'm wondering who makes them and if anybody has seen them in person. They looked pretty cool. Any info would be appreciated.

Yup. The fuel pump supplies way too much fuel--that's the way it is designed. The regulator is a spring-loaded valve. When the pressure "upstream" of it gets higher than the spring pressure, it opens up and lets fuel out until the pressure drops. So you have a source of fuel on the one end of the high-pressure loop, and you have a variable outlet on the other end. The section in between those is what is kept at the particular pressure.
