I can provide you with some general guidance on how to find the vacuum hose routing diagram for your 1986 Honda Accord.
Vehicle Owner's Manual: The owner's manual for your Honda Accord may contain a vacuum hose routing diagram. Check the section on engine specifications or emissions control to see if the diagram is included.
Underhood Sticker or Decal: Look for a sticker or decal on the underside of the hood or near the radiator support. Some vehicles have a vacuum hose routing diagram printed on this sticker for easy reference.
Repair Manual: A comprehensive repair manual specific to your Honda Accord, such as a Haynes or Chilton manual, will often include vacuum hose routing diagrams. These manuals provide detailed instructions and diagrams for various systems in your vehicle, including the vacuum system.
Online Resources: Search for online resources or forums dedicated to Honda Accord enthusiasts. Many online communities have members who share diagrams, tips, and information related to vehicle maintenance. These resources can be helpful in finding the specific vacuum hose routing diagram for your vehicle.

are you using a gauge? is this the 1.0L engine 3cylinders.
Trottle body injection (TBI) >
running or not?
the correct way to do this is measure at the fuel filter test port
ill quote the FSM
Relieve fuel system pressure.
Disconnect the fuel inlet line at the fuel filter and install a suitable pressure gauge on the line.
Connect a jumper wire between the terminals of the fuel pump relay connector and check the system pressure on the gauge.
Fuel pressure should be 25-33 lbs.
As the pressure reaches 33 lbs., the relief valve in the pump should pulsate the pressure so it is always within specification.
If the pressure is above specification, check for restrictions in the fuel lines. If no restrictions are found, replace the fuel pump. If the pressure is below specifications, check for battery voltage to the fuel pump and correct as required. If battery voltage is found, replace the fuel pump or fuel pump relay.
Before removing the pressure gauge, relieve the fuel pressure again.
Reconnect the fuel line. Start the engine and check for leaks.
