Usually the source of the leak is the gas cap (either loose or defective) but if that doesn't apply to your issue then the canister is next to the gas tank.

Whats the fuel pressure on 1997 buick regal LS


Richard, the fuel pressure is 40-47psi.

98 buick regal has a strong gas smell


Do you know what fuel pressure regulator is ? These like to leak when they get older !
The cartridge type fuel pressure regulator (1) is a diaphragm-operated relief valve (6) with fuel pump pressure on one side, and regulator spring (2) pressure, and intake manifold vacuum on the other side. The regulators function is to maintain a constant fuel pressure across the injectors at all times. The pressure regulator compensates for engine load by increasing fuel pressure as engine vacuum drops.
The cartridge regulator is serviced as a separate component. When servicing the fuel pressure regulator, insure that the O-ring backup, (3) large O-ring, (4) filter screen, (5) and small O-ring (7) are properly placed on the pressure regulator.
It's located on the fuel injector fuel rail !

Where is the fuel line located...I have to drain the fuel cell.


The fuel system is pressurized ... so you must relieve the pressure prior to doing anything with the fuel cell...
I find that this is easiest in the engine compartment at the fuel pressure regulator shrader valve ( looks like and opperates like a tire valve , only on the fuel line ).

92 Buick Regal idles too fast and sputters as if not getting gas. Changed fuel filter, didn't help.


Check the fuel pressure first, get the schematic for the pressure. I think it has to be between 37 and 45 psi. If the fuel pressure isn't in spec, then your fuel pump is to blame. If not then check fuel pressure regulator. Also, go to the library for a Chiltons or Haynes. Happy Hunting!

2000 Chevy Venture Fuel Pressure Regulator


use the pressure test port on the top of the engine, it is on the fuel rail that supplies fuel to the injectors, looks like a tire valve, will have a plastic cap on it.
