never heard or seen what that is. i'd rather do as little playing around inside the tank as possible unless there is a very compelling reason.

see timberwolf's posts here;

pumps over heating when you put in gas it cools down change pump if was oring whould have low preshure through all ranges

Ivans Imports - I'm hoping your diagnosis isn't correct from a $$ perspective, but it does seem to fit the symptoms. I've been failing in working out a plausible scenario where the o-ring would fail at lower gas levels.

Thanks - Jim

the beck ardly pump i get from lordco is about 150 $ was not to bad

[Jimbo67]

Thanks for the info on the pump..$150 seems reasonable. So far the car is running well, but I haven't really exposed it to higher temps with low fuel.

I do regular maintenance on the cars in April and Oct. so, one thing I did to day, was combine changing the fuel filter on the wife's 03 H6 OBW with installing a new , large-type cap and replacing the o-ring on the fuel pump.

here is another link to the youtube video with the best instructions; 2000 Subaru Outback Fuel Pump Assy - YouTube


a coupla notes on the above video;

I used a vacuum cleaner to police the area I was working to limit debris possibly getting in the tank.

Lower the windows/open the doors to reduce breathing fumes.

Be prepared for about 2-4 oz. of gasoline to come out of a coupla those hoses. If possible, thread a rag or 3-4 layers of paper towels under the hoses/cable before removing the hoses.

I used some twine to bundle the hoses and cable then threaded the twine up thru the driver's headrest post and pulled them up so they would be out of the way. Sorta replaced the use of the video author's wife's hands. Made it a one-man operation.

His fuel pump gasket came off with the pump. I didn't notice this before and had a more difficult time getting the pump out thru the gasket. So, make sure to free the gasket if it is stuck and carefully bring it out with the pump. Go slowly and carefully as it may be possible to break or bend something if you just 'horse' it outta there.

My original cap appears in great shape, the tabs do not appear to be cracked or bent. The o-ring was quite swollen however. I replaced the o-ring (lubed with a little oil) with the metric 928 Viton unit sent to me (thanx Dave L) and installed the new cap. I was careful not to rotate it too far as I think the 'bump/dimple' on the large tab is meant to stop the cap at the correct point. Forcing it farther would cause the bump to ride on top of the plastic lug and put outward force on the large tab.


so, still not sure if all these units are quite the 'ticking time bombs' I originally thought. The o-ring was definitely swollen so......

[CNY_Dave]

I am of the ilk that think the swelling o-ring breaks the cap, so I would say you dodged this bullet...

[1 Lucky Texan]

it was very swollen. I was surprised.

 

I may take the cap in to work to look under a scope but, it looked good.
