2GNT FUEL SUPPLY LINE SET UP
There are some basic instructions on how to set up a fuel supply and return system using #6 Stailess Steel threaded fuel hose.
Keep in mind that this is based on my intallation of the system on my car a 97 gs using a universal fuel rail supplied by MOTOFOOL. for some of the earlier year models, or those using the stock fuel rail some things may differ.
*About 20 feet of #6 S/S fuel line (you should only need 10 feet going each way. I bought 23 feet just to be safe, and to have a little piece of extra hose to go between the fuel rail and the SFMU, length depends on where you will place the SFMU). Get them pre cut, i will explain why later)
* MOTOFOOL'S Universal fuel rail (test port on fuel rail is 1/8th NPT so you will need an adapter that is that size and whatever size your fuel press sensor is NOTE: YOU MAY ALSO PUT THE PRESS. SENSOR ON THE SMALL HOSE LEADING TO THE SFMU, CUS IT'S A TIGHT FIT WHERE THE RAIL GOES)
**ATTENTION: this fuel rail is universal, mounting brackets need to made! **
* 2 feet of #6 s/s fuel line (cut in half for fuel presssure sensor. YOU MAY JUST GET A SOLID PIECE [if using the test port on fuel rail] TO GIVE YOU SOME SLACK FROM THE FUEL RAIL SO THAT YOU CAN PLACE YOUR SFMU IN A SECURE PLACE IN THE ENGINE BAY. LENGH OF HOSE WILL VARY DEPENDING ON WHERE YOU CHOOSE TO PUT YOUR SFMU)
* 8 -6AN Aluminum hose end fittings (6 pieces if not using fuel press sensor)
* 2 3/8th NPT to -6AN fittings for ends of fuel rail
* 1 -6AN Tee (FOR PRESS. SENSOR, NEED TO PURCHASE WHAT EVER REDUCER OR ADAPTER TO FIT ON SIDE OF THE -6An TEE TO THE SIZE OF YOUR SPECIFIC SENSOR)
* 2 feet of regular fuel line (this is to connect to the fuel supply line on the tank and then cut in half to pu in the fuel filter. you may use the main S/S lines for this if you wish to have it all s/s line, if so make sure to acomodate for the extra length when purchasing)
* 4 hose clamps
* zip ties[/b]
-Before working with the fuel system you must depresurise it. You will acomplish this by removing the fuel cap and letting some pressure out this way. Then take off rear seat (by pulling on the poins on the front). open the fuel pump access and unplug the ruel pump relay.
Crank the car and let it idle until it dies from fuel starvation.
-remove the return line (this is the one that is clamped using a hose clamp)
-Unfasten the fuel supply line. BE CAREFUL only twist the fitting on the right side, making sure not to bend or crack the solid line going into the tank. If you break it you will have to buy a whole new piece.
-Once those two lines are removed, jack the car up (always remeber to use jack stands when working under the car) and under the car by the passenger side rear wheel you will see the stock FPR and Fuel filter. Remove this whole assembly by unbolting the two screws holding it to the frame and then by unbolting the fuel supply hard line. Again the fuel line bolt is the one that turns. Careful not to break the line if you wish to use it later.
-Put the hose ends on the s/s hose pieces (your hose supplier should have given you instructions on how to do this). **IMPORTANT: MAKE SURE ALL FITTINGS ARE TIGHT SO THAT THEY WILL NOT LEAK! you may test them by running pressurized air through the hose while under water to check for air leaks in the end fittings. **
-The supply and return lines should only have one hose end fitting each, the other end will attach to the fittings in the tank with a hose clamp. *NOTE :the small hose that connects the fuel rail to the SFMU needs to have hose end fittings on both ends.*
-Attach supply and return hoses to fittings on fuel tank with hose clamps. Run the lines under the car and up to engine bay.
-Attach end fittings (3/8ths NPT to -6An) to both ends of the fuel rail, install fuel rail.
-Attach fuel supply line to the end of the fuel rail closest to the driver side.
-Figure out where you will place your SFMU in the engine bay. run your short fuel line to connect the fuel rail to the side fitting on SFMU (where ever it is solidly mounted).
-Attach fuel return line to bottom fitting on SFMU.
-Either plug or attach fuel pressure sensor fitting on test port on fuel rail. (PLUG IF PUTTING THE PRESSURE SENSOR ON THE HOSE LEADING TO THE SFMU)
-TURN CAR ON AND CHECK FOR LEAKS, TIGHTEN WHERE EVER NEEDED. YOU ARE DONE!
