Thread: 4bd1t injecter pump boost diaphragm

My injector pump has a diaphragm to deliver more fuel under boost,can i replace it without removing the pump.
would appreciate any advice.Phil

Thanks for help, it was just the gasket holding on, i taped a kitchen knife carefully down into the gasket and the housing popped off, there was 2 small holes in the diaphragm, hopefully that is where i am losing power! Rang looking for new diaphragm $50 plus $10 for gasket.
