| Most of the pressure fittings and gauges can be found at your local Ace Hardware Stores. The larger onese carry a nice selection of brass fittings and adapters. If you can't find a few parts, try some other hardware stores. Some larger auto parts stores carry brass fittings for special work in pressurized systems. They usually stock everything. The fuel injection hose and clamps can be found at mostly all of the available auto parts stores. If you want to be able to see the gauge while you drive, get a couple of feet so that the gauge can be located outside the hood. |
| PUTTING IT TOGETHER |
| Use the diagram from the top of the page to assemble the fuel pressure gauge. Use: hose clamps at all hose connections; Teflon tape on all pipe threads. Cut the length of hose so that about 3 to 6 inches goes between the fuel rail and the "T" fitting, while the rest goes between the "T" fitting and the gauge. |
| Installation |
| The gauge gets installed between the fuel supply line and the ouput (bowl, fuel rail, Throttle Body"TBI".) When removing a fuel line, always make sure you RELEASE THE FUEL PRESSURE on the system, or you MAY be sprayed with fuel. You can do this by taking the cap off the service valve on the fuel rail and pressing the valve stem in the center (USE A WRAG.) This is not meant to be a permanent installation! You don't want this hanging here while drivng normally. Do not install it on the fuel return line, either. You will not get any semblance of a proper reading There. |
