I’ve got a 90 4wd loyal wagon spfi with about 230thow on it. I'm guessing the fuel pump is located in the back because I can hear something running. Does this mean that it getting ready to go, or is this just a normal noise? How hard is a pump to change? Just notice it because the radio went out just last week.

the fuel pump in my 85 brat is noisy as hell, still seems to work fine. its been that way since i bought it 10k ago. the one in my 78 brat is mounted under the hood and is silent.

I've had SPFI cars in which the pump made no noise, and SPFI cars in which the pump made a definite humming-type noise. None of them failed, at least in the time that I owned the cars.

I only feel comfortable if I can hear my pump. I know it's not going to leave me stranded (it's happened before, that's how I know).

the pump is very easy to change. It's right in front of the right rear tire. Three bolts hold the bracket to the car. Remove them and it drops down where you can uplug the harness and unclip the two fuel lines going to it. If you ever do have to change one, have a drain pan ready to catch fuel while you shove the new pump on.

 

the pumps in my cars make a bit of noise... usually in time with the turn signal

You can also just clamp off the line between the tank and the pump with some vise-grips.

 

The pumps are really easy to change (takes about two minutes). They're horrendously expensive new, so I'd get one from the junkyard to have on hand if you're thinking it might go out. Some people have also had good luck running a pump from an older F150, which costs a lot less than the regular subaru pump.
