Section 6 – Final Checks and System Start-up
6-1.
Ensure that any spilled gasoline and any gasoline soaked shop towels are cleaned up and removed from the
vicinity of the vehicle!
6-2. Carefully lower the car onto the ground.
6-3. Fill the fuel tank with gasoline and check for any leaks in the system, if any leaks are found repair immediately.
CAUTION:
While performing the following steps, if any fuel leaks are detected, immediately turn the ignition of
OFF, remove any spilled fuel and repair the leak(s) before proceeding!
6-4. Reconnect the battery and turn the ignition to the ON position
WITHOUT
starting the car. After several seconds,
check the fuel pressure. If there is no fuel pressure, turn the ignition key to the OFF position, wait one minute, return
the ignition to the ON position, and recheck the fuel pressure. Repeat this ignition OFF and ON procedure until the
fuel pressure gauge registers fuel pressure.
6-5. With the fuel pressure gauge registering fuel system pressure, check for fuel leaks throughout the entire fuel
system! If any fuel leaks are found, turn the ignition key to the OFF position, remove any spilled fuel and
repair the leak before proceeding!
6-6. Once the fuel pressure gauge registers fuel system pressure and there are no fuel leaks, start the engine and adjust
the regulator to the desired fuel pressure. Turning the adjustment screw clockwise will increase fuel pressure. OEM
regulators are typically set at approximately 43 psi, without the vacuum line attached. The fuel pressure adjustment
range for this regulator is 35-80 psi.
6-7. Once the desired fuel pressure is achieved, tighten the regulator adjustment jam nut and attach the vacuum line.
6-8.
Test drive the car to insure proper operation and re-check the fuel system for leaks.
If any leaks are found,
immediately discontinue use of the vehicle and repair the leak(s)!
Section 7 – Filter Maintenance
Follow this procedure to check and clean the filter element contained in the fuel sump.
7-1. Raise the vehicle and support it with jack stands. Disconnect the battery ground cable.
CAUTION:
While performing the following steps, a small amount of fuel will leak from the sump filter assembly.
Extinguish all sources of ignition and prohibit smoking in the area before continuing. Make sure there is an
approved fire extinguisher nearby.
7-2. Place a small drain pan underneath the sump. Remove the 8-32 screw and lock washer locking the filter endcap in
place.
7-3. Turn the filter endcap counter clockwise until the tabs on the endcap line up with the slots in the filter cover. Pull the
endcap out of the filter housing and set aside.
