26. Using the included hard plastic vacuum line extend the factory vacuum line to the fuel pressure

sensors new location. Cut a short section of the supplied rubber line to connect the hard vacuum line

to the fuel pressure sensor. Excess lengths of rubber line can cause false readings under vacuum

conditions due to the rubber line collapsing.

27. Reassemble the vehicle using the reverse of the foregoing removal procedure.

28. When installing the fuel pressure sensor in the Aeromotive fuel sensor adapter block, it may be

necessary to bleed any trapped air from around the sensor. Failure to do so could result in random

hesitations and/or ill performance.

29. Remove the 1/8 NPT pipe plug from the fuel supply adapter tee fitting and attach a suitable fuel

pressure gauge if desired.

Ensure that any spilled gasoline and any gasoline soaked shop towels are cleaned up and

removed from the vicinity of the vehicle!

33. 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.

With the fuel pressure gauge registering fuel system pressure, check for fuel leaks from and

around the Aeromotive fuel pressure sensor adapter, fuel rails, all fuel lines and connections! If

any fuel leaks are found, turn the ignition key to the OFF position, remove any spilled fuel and

repair the leak before proceeding!

34. Once the fuel pressure gauge registers fuel system pressure and there are no fuel leaks, start the

engine.

35. Turn off the engine and allow it to cool. If you do not want to keep the fuel pressure gauge on the

vehicle, relieve the fuel system pressure as instructed in the appropriate vehicle service manual.

Remove the fuel pressure gauge and reinstall the 1/8 NPT pipe plug, using thread sealant.

36. Test drive the car to insure proper operation and re-check the fuel system for leaks. If any leaks are

found, immediately shutoff the engine and repair the leak(s)!
