2000 V70 XC Fuel Pump Replacement

jarc00 · Post by **jarc00** » 18 Aug 2008, 21:33

I bought a 2000 Volvo V70 XC two months ago for my wife. It has 140k miles on it, and hopefully many more. We live in SW Missouri and have taken the two trips outside our local area in the vehicle. On the first trip it started overheating 160 miles from home. I replaced the thermostat in a Home Depot parking lot and it fixed the problem.

Last month we went on a longer trip (250 miles) and on the way back the car died. It would crank over, but would not start. I called a local shop and had it towed in. (No dealers for 150 miles, same for my house) The shop was a Volvo specialist and said he had the Volvo scan tools. He diagnosed the problem as the fuel pump. I did purchase a new Fuel Pump Relay to try before I had it towed, I'll use it when I replace the pump. Apparently it takes a special pump for the AWD and he did not have any in stock, he said it would take a week or two to get the parts and fix it. Not wanting to leave the car there, rent a car to go home, and take a trip back 250 miles each way, I had a family member come a trailer the car home. The $1300 price tag without all of the extra expenses seemed a little steep as well.

I have just removed the fuel pump, which was a nightmare. (Removed the drive shaft, loosened the exhaust, removed most bolts from the rear sub-frame/suspension, etc) The information I have found online states I need a pump numbered 9470674. When I removed the pump, the wiring had the same number on it. The actual pump inside the housing was marked:
Walbro 04
29699-1M1
GRJ 235
The pump when hooked directly to 12V works.

Sorry for the long background information, Now to the questions... I disassembled the pump and found a blue washer with a metal base on the top of the pump that was cut. (I have a picture if needed) Can this washer be purchased separately and installed or do I need to purchase a whole new assembly? If a new assembly is needed, where is the best place to purchase a part? Prices range from ~$700 at a dealer for OEM, ~$500 online for the same part OEM (www.tasca.com), or $300-$600 from various online retailers for an aftermarket part. (Which looks slightly different)

I hate to spend more than needed to fix what appears to be a simple washer problem. On another note, someone pulled out in front of me a few days ago and we wreck our other vehicle. It is now in the shop, (I can do mechanical work, but I don't have the skill or the patience for body work), so now have no driveable vehicles. Any help or suggestions will be greatly appreciated.

John, welcome to MVS. You've come to the right place for most of your repairs. It appears that someone has already replaced that pump for a Walbro. Some have had great luck with these and some have not. Take a look in the repair database section for the transfer of pump and pump parts. You might opt to get another Walbro and take your chances. Who knows when that one was replaced. Conversely, if you want a new OEM (Volvo) pump with all of it's parts, you might check www.fcpgroton.com and/or eeuroparts.com It will be more expensive than the Walbro but certainly cheaper than the dealer for the same part the dealer would be installing. Hopefully the write-up in the repair database will show the particular washer you speak of and answer your questions and at the same time save you some $$.

MadeInJapan, Thanks for the quick response.

I've been having trouble finding info on the AWD fuel pump. I think my only problem is the washer that seals the top end of the fuel pump to the plastic housing. Most pump kits that I have seen do not include the washer, just the pump and strainer, etc. I have not been able to find a rebuild kit or even just the pump for the AWD pump.

A picture of the washer is below. Any ideas to find the washer/seal? Or, am I stuck with buying a whole new pump assembly?

Thanks.

I looked it up in VADIS and it doesn't call the grommet out as unique part. Perhaps a salvage yard or www.erievovo.com. The picture will be helpful for them to figure out what you are after.

We went to a local salvage yard looking for Volvo parts. They only had one Volvo and it was FWD so it did not have the same pump.

The yard had several fuel tanks out laying by the vehicles they came out of. On a whim, we checked a few of those pumps.

We found a early 2000's Chrysler minivan that had a slightly different pump, but had the same washer/seal that I needed for the Volvo. The Chrysler pump was numbered:
4809092A
97082E

We took the parts home and were in the process of installing the new washer, when we realized that the plastic housing was cracked where the seal seats. Most likely, the combination of the cut seal and the cracked housing led to the low fuel pressure problem.

Ordered a new Volvo OE and waiting for it to arrive. The package is scheduled for delivery on 08/25/08.

I'll post a few pictures and a walk through of the process as soon as I complete the installation. I had a lot of trouble finding information on the V70 XC or AWD models, hopefully the writeup may help others.
