leakyheadgasket 2000 Legacy here, just got through dealing with the same issue. My mechanic tried to tig-weld the cap but it only lasted a week at best, so I had to replace it with the NPN kit that everyone here is referencing.

One thing: I decided to go with a 90A durometer o-ring (from Amazon... I have 9 left, sigh), which is quite hard. I figured if the problem is the o-ring blowing out, then the harder one will be better. When I got the assembly off it definitely seemed like the original part was a softer o-ring, of the typical 75A durometer rating. But the new cap went on (after a bit of an argument) with the harder o-ring just fine, and the car is working fine now.

ThomasJay I just opened up my fuel tank.

The o-ring of doom got me, too.

2001 2.5 liter SUS.

This sucks.

it does seem to have the sender and some gaskets separated out. I was hoping the cap and o-ring might also be listed separately.

Anyone have access to TSBs ?

There may be a breakdown of parts now making it easier to repair the pump.

wilsonhp A high pitched squeal from the tank area is the sound of a normal pump running. On any car, turn the key to the first position (before starting) and listen. the pump will run for a few seconds to pressurize the fuel rail. it will sound like this-a high pitched squeal. once the car is running, the sound is overwhelmed by the running engine sounds and you never hear it.

the squeal does NOT mean it is bad.

Dodik generally high pitched sound from tank would be fuel pump going bad from my expirience
