On my 2001 P5 im doing my fuel pump and i noticed my factory one has that nipple on the bottom and my universal does not. everything else fits and all. Is not having that nipple going to be an issue with picking up fuel?

If you have the plastic fuel tank with cross over tube to the other side of the tank, as my 2001 V70 T5 has, then I think you are going to need some way to connect to the crossover tube.

Ahhh I Figured that's what that little nipple was for.

From the design of the pump it "looks" like the cross over tube doesn't connect to the pump its self BUT fed in though the return. Does fuel feed from one side of the tank to the other using return line pressure?

Fuel pump is one item I always go with genuine Volvo or Bosch (Bosch is $150-$200 etc. at FCPEuro) bc:
- The fitment is perfect.
- Should last another 160K-200K.

So the cost for the next 160K-200K is not that bad.
Plus less chance of being stranded somewhere.

PS: Walbro is a good brand but somewhat noisy...

I can't remember the details on the crossover flow connections and I think I discarded my old hoses when I changed the pump. Try to search this forum for more pump/hose details.
If you are not replacing the tank cap over the pump, look closely for any cracks in the top of the cap. These cracks are a known failure point and will cause a fuel leak and fuel smell under the car. One solution is an epoxy plug over the cracks. Again, search this forum.

The pump fit right in. The change over is fed though the return that’s why it runs to the other side of the tank I think. But going on two weeks and still all good fuel pump wise. Now chasing another issue.
