Reply to "Fuel pressure ok?"

Boss Wrench is right could be a hole in the diaphram. Maybe areomotive might sell just that part as a repair kit.

A hole in the diaphram would explain why you don't hold pressure when the engine stops. It would explain why the fuel pressure does not move from 40 psi. It would explain why the car is not running well.

You are right the hand pump should pull a vacuum and hold when you stop pumping.

If you do get the small hose off you will have fuel present IF the diaphram is ruptured.

You might take a electric heat gun or a hair dryer to heat the plastic line to soften it. to aid in removal. NO FLAMES might encounter raw fuel and that extingisher!!!

If the diaphram is ruptured , it has been adding fuel like a 9th injector.

Might sniff the oil on the dip stick to see if there is raw fuel in the pan. That would be extreme but doesn't cost a dime.
