The past few times I’ve tried to fill up the gas tank the pump keeps shutting off after just a few seconds, no matter how slow you try to pump in the fuel. It took me a while to finally get the tank full. This is new behavior for this car. As part of the diagnosis, I decided to check out the roll over valve to make sure that it was allowing the vapor from the tank to pass through to the charcoal canister during fueling.
We have a Category Red issue happening now. MVS Forums member Jeeptroll’s 2006 XC90 V8 was vandalized in Washington, D.C. The vandal(s) put debris in the gas tank after prying open the fuel filler door. The debris could be sugar and plant matter. The XC90 was of course disabled, and he towed it 180 miles […]
Shockwave has good patience and great DIY XC90 V8 intermittent fuel pressure diagnosis chops. Just have to get that out there. If you’re diagnosing a fuel cutout condition on a XC90 V8, this XC90 V8 intermittent fuel pressure forum topic is gold.

Longtime MVS Forums member Geevs asks about Amsoil’s Power Foam intake & combustion cleaner, and gets many good responses and alternatives. MVS Contributor kcodyjr… Sucking something in through the manifold causes the engine to stall, and the chemical sits on the pistons and rings. You let it sit, then start it up to burn it off. […]

MVS member Auburn T5 goes bananas on fixing up a 1998 Volvo S70 T5. Stage 0, new transmission, new struts, shocks and springs, you name it. Documented with photos too. Did a lot of stage zero work – inspected vacuum lines, changed oil filter, fuel filter, top motor mount, k&N panel filter, timing belt, water […]
Well it is time for me to be schooled! I have been told that the 99-00 AWD cars had 2 fuel pumps. I will now post pictures of the 2 items just replaced on my car, and then perhaps someone can point to me where I am not seeing a pump mechanism on the LH ejector.
So below are various pictures of the RH fuel pump. This has 2 pipes on the cover plate. The RH one looking at the top connects to a pipe on the LH side ejector ‘pump’. The LH pipe goes to the fuel filter and then onto the front of the car and engine. See picture RH pump (5).
So if anyone can now explain to me where the 2nd pump is, please add notes below. I’m always wanting to learn! Also, now if someone can explain to me why the ejector ‘pump’ is about 20% more expensive than the main pump assembly, again, let me know.
Strangely the pump is the cheaper of the two. I purchased from Tasca from whom I purchase most of my part in the US. If I recall, the pump was about $330 and the ejector about $370. So about $700 for both parts. The price may be different for a 98 as the system was a little different, and I don’t pay any US taxes. Just checked on Vida and looks like the pump and ejector are the same for 850AWD to 2000 V70 AWD of all variants.
