You can't tell much from a squirt test or an open pipe look.
Use a gage on the closed system to know, so the pump works into the pressure load it is designed to do.
Good luck.
OK, thank you.

I was just approaching this thinking that I'd somehow see some fuel at the rail at 35 psi. Just doesn't make sense that it could be pressurized and, upon opening the valve, no fuel would come out.

But since the classic reply is usually "clean out the tank" then... that's where I'm at right now. I'm going to drop it shortly and just take a look around inside of it to see if this was valid advice. Thus far the fuel I've siphoned out looked good.

exactly what I was trying to say. running a test with fuel pump out wont really show true results. most fuel pumps even though they may still work outside of the vehicle, may not work well when in use inside of the vehicle.
