Fuel pump top flange leak, recall?

Post by Mikele82 »

So having a slow leak, found its from top of fuel pump.
I see its common and many 7$ fixes on it.


was thinking this is serious and found there was a recall on it.

OR probably isn’t in the climate zone covered, but your dealer might cover it. You will have to pay For diagnosis and it may not qualify for replacement if no fault is found.

You probably have a month left on the recall clock; typically they are 10 years

I replaced my entire fuel pump assembly a year ago at about 180,000 miles after finding this leak. I figured it was a good time to install a new fuel pump and have assurance that would not be a problem for a long time. I replaced the fuel filter a few hundred miles later because I thought I got some dirt in the tank during the change. Lots of good info here on how to change the pump assembly. Hardest part was getting the lock ring loose that seals the tank openings. Had to buy a universal tool for this.
DO NOT start the car with the rear seat belts disconnected. It will throw a code and you need special scan tool (or dealer) to reset. (things I must learn the hard way.)

I had this issue with my XC90 - same design, maybe same pump.

I cleaned it all nice and good - gave it a sanding to scuff the area and the walls - then another good cleaning. Then I filled it with a 2 ounce package of JB Weld. I did it in two stages - first coat and then second coat about 4 hours later (summer) - gave it time to firm up but not completely set. As the epoxy is self leveling and the pump has a slant to it - I did it this way so I could get enough material on the walls.

I trust JB Weld in this application - other epoxies have not impressed me. The downside to trying to glue it is not that great, other than time and the epoxy. If you have no success it doesn't cause any harm. Worth a try.

The two ounce package is two tubes of one ounce. I coated the entire bottom and then up the walls as high as I could go (it is at a slant) - then came back and leveled out the other side. Has been about 8k miles with no issues.

I did it about 5 months ago - and no leaks.

Usually I do a full repair and that was my plan until I saw the problem and researched the repair. Figuring the age of the car, and how easy it is to get to it made since to try the $8.00 repair. So far no issues. Car is now in my sister's fleet and she is racking up the miles.

If you try the epoxy fix - just make sure to clean the area really well, rough it up for glue bite and clean it again. First disconnect the battery and then disconnect the fuel line as you don't want any pressure. Then fill the entire cavity with epoxy. Let the final fill fully cure before you put it back in service. If you have doubts, drive it around a day or two without putting the interior back together. As gas smells and you can see the problem - you will know if the fix works.

Use JB Weld, I have seen some people use cheap epoxy, and that stuff gets gooey over time.

Someone did a great write up on this and actually showed the point of failure on the white cup, not to take anything away from this repair, maybe a couple of years ago?

And just to add some caution on this idea -

Epoxies do not stick / bond to plastics. That is why you mix them in a plastic cup or mixing board before you apply them. When it's cured, it just pops right off the plastic. They'll bond to metals, wood, brick, concrete, clay - all kinds of things, but not most plastics.

The recall only covered certain VINs in certain southern (warm) states. Kind of a Volvo rip off, I know. You can call Volvo customer care to see if your VIN is included.
