I'm assuming this is for a carb application. EFI would be different
Fuel tank --> fuel filter --> mechanical fuel pump --> fuel pressure regulator --> fuel pressure gauge --> Carb

Jake nailed it. The pressure behind the regulator is irrelevant and there is no pressure behind the pump.
FWIW I like to run a filter before the pump and another finer one before the carb. The modern gasahol cleans stuff out like you would not believe. |

| I just replaced the big inline filter before pump. I am going to replace the filter the screws into carb this week. I need to cut some of the hard line from pump to carb to have enough room for gauge and regulator. Will a cuyyer for copper pipe work |

Peanut cutter is your best bet. Any hardware store will have 'em cheap, or borrow one from a plumber.
You might also consider renting a flaring tool to throw flares on the lines. I have seen clamped rubber hoses slide right off of straight-cut steel lines. |

| I was thinking about buying the flaring tool kit they have at harbor frieght. I know that they are cheaply made in a foriegn land, but I figure I will only use it a few times. |

| Harbor freight tools are hit-and-miss in my opinion. Don't know what your budget is, but for something critical, I'd spend the extra money and get a good one. |

I bought the Napa flaring tool and it was crap. I took it back. _________________ A redline a day keeps the carbon away! |

When I did my brakes I borrowed Al's flaring tools. One he had was a VatoZone special and the other was Napa. They were basically the same quality.
Regardless, the flares in this case are only holding the hose clamps in place, so they don't need to be pretty. I would just rent the tool. |

Best way is to use a double flaring tool and only HALF flare with the first step. It gives you a nice NUBB to keep the hose and clamp from sliding off. Works awesome. _________________ A redline a day keeps the carbon away! |

| So I just hooked up gauge. Before I even hooked it up it read 2 psi . The gauge that is. Is that normal or is it faulty out of the box. And then when I fires it up its reading about 10 pai which I know is high , but it is rather erratic. Is that normal |

At least run the Summit brand gauge.
BTW, don't get a liquid filled, it goes south as it gets hot. |
