Has anyone had a fuel pump,that tested with good pressure.But failed at fuel volume?
I really think that is my problem all along. |

yes sir,new regulator,pressure rises to 60 psi under light load,never checked high load.Car feels like its running out of gasoline.I heard a pump can test good on pressure but fail on volume. Pump has 178,000 miles.

IF ... you have a check valve in the return line check that.
Bought a lovely Volvo wagon with a bad check valve. A quarter got me a good working one at pnp. |
A clogged fuel filter can do that.
Also gas tanks can have crud inside them which restricts flow. You can use a lighted USB inspection camera to peek inside the fuel tank. |
I'm going to do the 35 second test with a one liter bottle.If it fills the bottle its ok.
