'94 850, but probably applies to all.

I've been having an intermittent leak at or near the fuel pump. I replaced the seal between the tank and pump, but it did not help. The fuel lines themselves have no cracks or breaks, so I am now wondering if it could be the O rings in the quick connects on the fuel lines. Are the O rings replaceable?

(ahem) Sorry, it wasn't the 850 making stinks in the driveway this time (it still may in the future, I don't know) It seems the 122 is the current culprit, but what do you expect with a 40 year old gas tank?

Just looked it up on a VADID and what I find is no O rings. 9142683 and 9162886 seem to be replacement ends. Might want to go to a bone yard for parts as I have never heard of these leaking before. Might want to call fcpgroton and see if they have any knowledge of these part numbers.

Good luck,

Any responses anybody? Please?

They looked replaceable to me. I can't imagine they wouldn't be, but I am by no means the last word on this one.

You've probably been through all this, but have you tried searching the archives? Or perhaps you would find them in the catalog of an online parts store to confirm that they are available/replaceable.

Shame you can't find the culprit. If I recall correctly, you've been dealing with this problem for a little while now. What's the symptoms? My big nose usually leads me to a fuel leak...



Good luck,

I'll probably just go by the dealer and see what's in the parts manual, in case it is an odd size o-ring or something.

I have indeed been fighting this a while, as it does not always occur, yet when it does, it is only overnight after a fill up. I can fill it up in the morning and leave it all day in a hot parking lot and have no problem, then drive 3 miles home, and overnight, I'll smell gas outside the car. And of course it normally happens when I can't take the time to see where it is coming from, though I did recently have time and pinpoint it to the fuel pump.It's not big leak, never hitting the ground, just smelly and of course it's not safe.

I replaced the fuel pump to tank seal, and it did not fix the problem, and the tank had no defects that I could see. So it is either the o-rings, or the pump itself has a problem. Still it's odd that it only happens overnight when the fuel would contract from cooling, and so far I've not had it happen during the day when you'd expect the fuel to expand and possibly leak.

I'm an idiot sometimes. For some reason I thought you were talking about the injector o-rings. That explains why you couldn't pin-point the problem to under the hood or near the tank...

I think you may be on to something with the connections at the ends of the fuel lines, but I'm wary of it because those connections seem pretty foolproof.

I'll ask obvious things: You park in a garage at night, ie enclosed area where you're more likely to smell fuel (explaining the odd timing of the smell)? Filler tube or filler tube connection to the tank?

This is a longshot, but has your car had the recall fix for the fuel tank? Apparently the tank could crack due to the mounting points or something. I got a letter from Volvo and took it in so they could inspect the tank and add some rubber bushings to the tank mountings or some such thing. This was around 2.5 years ago. This was only applicable to certain states with colder weather. Let me know and I'll pull the letter/dealer invoice from my file.

Nope, the garage houses either the Studebaker or the 122, depending. The 850 and the VW Pissant have to live an undignified life under the tree near teh bird feeder.

It's not the fuel filler, and when I found the leak, gas was puddled in the dimple on top of the tank, AND inside the locking ring on the fuel pump, so the immediate area is pretty apparent. The car has gone through the recall, and oddly, the problem started after that, but of course the dealer claims they didn't do anything to cause this leak.

I'll have to look into the replaeable ends on the fuel lines like someone else suggested.

Thanks
