Re: Fuel Pump Pressure??

That's certainly one way to test a fuel line. My own preference is, instead of using pressure, to use vacuum. I disconnect the fuel line at the tank and at the pump. Attach a vacuum gauge at one end and a vacuum pump with a valve at the other. Pump to pull a vacuum of 15 or so inches of Hg, and valve or otherwise close the end, and check the residual vacuum the next morning. If you held the vacuum overnight you can have high confidence the line is tight.
