Help With Fuel Line Part ID

[VolvoTurbo850]

old vadis numbers are 9186290-0 which replaces 9445392.

Wonder if you could get by just bypassing it.. don`t roll the car over

I can't make much sense out of the hose diagram since it doesn't include the filter or FPR. I wouldn't even attempt to bypass it since I have no clue what it is. I'm guessing it's there for a reason. One of the things I like about Volvo is they seem to think of everything. One of the things I don't like, is you have to find a mechanic that does too. The closest Volvo mechanic is 45 minutes away, and even if I could get it there I couldn't afford it.

The rollover is right beside the the filter you can see the edge of the filter.

The rollover connection is if the car rolls over it will shut the flow of fuel to the engine. You can see that the nipple the hose goes into is rusted off.

If you could either use the proper connections to remove the connector and bypass it then your okay. However, if your not comfortable with the unit (because this is a gasoline connection) then don't do it. You can have a local mechanic do it. The only problem you may have is if the line is a quick connect and there is not way to connect both the female ends together on that coupling.


Perhaps the best solution is to find a wrecker who will let you pick it off the unit and replace it. Only other option is order it from your volvo dealer and have him ship it as some of the sponsors of this site do.

OK so to clarify that I haven't confused parts here... in the 2nd picture from my original post, the silver/black cylindrical part (middle right) is the FPR and not the fuel filter? The fuel filter is the large cylinder (which you can only barely see the end of) in the lower left of the second picture. If this is correct then I should be able to get the JY to pull the part for me and, like you suggested, get a local mechanic to replace it or do it myself if I can do it without screwing up the existing lines. Is there a trick to removing/replacing the lines without ruining them? It's clear that the part that broke is broken off in the line coming from... what I thought was the fuel filter.. closest to the tank, so I'll have to get that out somehow. I searched for a rollover valve online previously to see if it matched and didn't have any luck. Thank you everyone for the feedback!

Actually google just pulled up this post: https://www.matthewsvolvosite.com/forums/vie ... 52&start=0

With this picture: https://www.matthewsvolvosite.com/forums/dow ... d=5161&t=1

and that's exactly what the lines under my car look like, only much cleaner in the above picture. Too bad they didn't label the rollover valve and FPR if that even is the FPR

[VolvoTurbo850]

yes you got it.. good luck!

[Georges96850]

Great, Thank you! Tomorrow I'll hunt for a replacement...

Well, apparently the largest salvage yard in the SE doesn't have the part in any of their yards. They pulled the wrong part twice even after I sent them many pictures. They remove the gas tanks from the vehicles and the rep i talked to thinks they remove the valve when they do that. Of course, why would the fuel filter still be on the vehicles. The rep also called the volvo dealer who said that the part can only come off a '96-7 volvo 850 after he'd pulled one off a 70 series. this part doesn't seem to exist online... not sure how smart it would be to bypass it or even if i could... the frustration continues

[Georges96850]

Had the dealer order me a new roll-over valve. It definitely is NOT the correct part, and this explains why the salvage yards couldn't find it. Whatever this part is, it connects directly to the fuel filter via a short piece of fuel line (see pic attached). The Fuel Pressure Regulator sits on top of this piece, and apparently connects to it because I wasn't able to remove the FPR after unscrewing the screws (though I didn't force it since I wasn't sure).

So... does anyone have any idea what the fuel filter connects to on a 1996 Volvo 850 non-turbo? The only other option is to have the car towed to the dealer which is an hour away. Thanks for any info!

I know what this piece is, what it does, and where to get it. Technically, it has no individual name. You can only buy it from the dealer as part of the entire fuel line from gas tank to motor. I paid $243 plus tax. My problem (now resolved) was wanting to add a Walbro fuel pump and 4 bar FPR to my system. This part is for those of us with the FPR back by the fuel filter near the rear axle passenger side. when I first snapped the little nozzles off I tried all kinds of crazy fixes such as drilling them out, putting in bigger connectors, clamps everywhere, My fuel line looked like Frankenstein's Monster. The fuel pressure regulator has two hoses attached, one is vacuum to move it's internal diaphragm, the other is the return line to your fuel pump. The "mystery part" it snuggles into is flowing fuel forward: Pump, filter,mystery part, engine. Since I am using a FPR that makes 4 bar of pressure instead of 3, there is a lot more pressure in the fuel lines. I spent days playing whack-a-mole with fuel leaks. I finally broke down and bought/installed a new fuel line. No leaks, just plenty of fuel to supply my greedy green injectors. I will warn anyone trying to scavenge this part at a junk yard rather than paying for the line. you must cut back your hose to where the inside plastic is good, then put it in boiling water to make it malleable before connecting it and using a good fuel injection style clamp.
