Default car trouble, need advice

2000 i have a subaru legacy that's been having stall out trouble at speed, however is seems to only happen whem my tank gets lower that halfway full and when i go up hills. i think it's a fuel pressure sensor, but i need to if it could be something else so i can weigh my options. thanks

Whats a fuel pressure sensor?

Could be anything, fuel filter, aged ignition system etc.

oop, i think i meant regulator. i tried replacing my filter, no change. new plugs, no change. maybe plug wires? highly doubt it but i'm due for some anyways. problem gets progressively worse the less gas in my tank, till eventualy it stalls, backfires and takes off again. the feeling is just like a sudden, progressive loss of power till the (i'm guessing fuel system) is able to get fuel flowing...

is it cold where your at?? Ive had a few problems with cars building up ice around the fuel sock. this is ok on a full tank because it floats to the top, but once your fuel level drops, it covers the sock completely. highly doubtful but just an idea, try some isoheat or other water removing fuel additive.

Just a guess mind you, but if there was a small hole in the fuel line inside the tank about halfway down, it would mimic those symptoms

not really i have seen this before in a legacy it was th part that holds the pump to the sending unit wouldn't hold the pump in place because it broke and allowed the pump to suck air. try pulling the pump and inspecting it. they are very easy to remove
