Dunno what pump it is. The top of the entire unit (pump, fittings, fuel level sender) said ford on it. But the pump itself says BOSCH. I am not the original owner, so I have no idea if it was ever changed.

I just wish someone could tell me the fuel pressure specifics.
Maybe similar results??





Sounds like pump was changed if it says Bosch.

as for fuel specs.
From my ford service cd.
From what I can tell this is on priming, key on, engine off.
Is fuel pressure between 35 and 40 psi (240-280 kPa)?

Verify fuel pressure remains within 5 psi of the maximum pressure for 1 minute after turning pump off.

Disconnect vacuum hose at the fuel pressure regulator and plug it. Drive vehicle with heavy accelerations while observing fuel pressure gauge reading. Does fuel pressure reading hold steady within 3 psi during test.

If your only getting 20 psi on the first prime, my guess is the pump is bad.

I had a similar issue, but mine was priming at 5 psi.
i.e. every time I cycled the key on, the gauge would read. 5, 10, 15 etc......
