Hi there
It would help if we knew what model Morgan and which engine you have, we could be a little more specific in our help for you.
For the Rover V8 engined +8s , the meter is plugged into a valve on the fuel rail at the back of the plenum chamber on the driver's side. The fuel line pressure that +8 is 40 psig.
Apologies , I have just realised this was posted in the M3W section so we know what the car is . My mistake. Sorry I don't know enough about this model to give you an informed answer.
