Maybe you could enlighten me on that. Thanks  |
The Fuel Accumulator is on the return side because it has a diaphram and spring inside to hold fuel pressure so the engine re-starts quickly. If the diaphram/spring is defective, fuel will bypass the diaphram and return to the gas tank via the rubber hose attached to the rear of the Fuel Accumulator.
You might try pinching off the hose or disconnecting the hose on the rear of the Fuel Accumulator and blocking the rear outlet with a short hose and blocking it with a bolt and clamp.
Then try checking the fuel pressure to see if it is higher than the previous 16psi.
Just a thought without buying any parts to see if you can isolate your low fuel pressure problem.
