REMOVE FUEL TANK CAP BEFORE RELIEVING PRESSURE
TECHNICAL SERVICE BULLETIN
FUEL TANK PRESSURE
Model(s): All Acura Models through 1987

SERVICE INFORMATION
Here's a simple little note to remember when relieving fuel pressure:
Before loosening the 6mm service bolt on top of the fuel filter, remove the fuel tank filler cap. This relieves any pressure that may have built up in the tank, and will cut down on the amount of fuel that squirts out when the service bolt is loosened.
