On my 87 BGN running a TE-60, 50lbs. Injectors w/chip for 50lbs. Injectors my adjustable fuel pressure regulator stays around 40lbs when running with vacuum line on. When the engine is not running and I turn the key to engerize the fuel pump fuel pressure goes upto 40lbs. After the pump turns off fuel pressure drops immediately to 20 then bleeds down to 0 after 30-45 seconds. Have changed the feed and return o-rings off the fuel rail (both purchased from dealer).
Any other ideas?
