I wanted to see how complex the P2 fuel assembly is after being quoted over $380 locally for a Bosch 30761743 which includes the sender and the pump as one unit. I didn't want to wait 10 days for a pump assembly from Tasca (just over $209USD which is not a bad deal at all) so I decided to see how different a P80 (Gen 1) pump is. I found a seller locally selling Bosch pump 0986 580 979 to suit P80s for $78 AUD. The ad claimed it suits C70s up to 2002 with the B5244T engine so it must have similar specs.
PARTS/TOOLS REQUIRED:
1) Hammer (my favourite tool)
2) 25cm (9 inches of submersible fuel hose)
3) Bosch pump 0986 580 979 comes with 2 X quality clamps (other parts in the fitting kit won't be needed)
4) 1 X axle bolt or 10mm threaded rod to push pump out of filter fixture
5) Gauze filter (I used an Aldi shopping bag pre-tested for fuel compatability)
6) High tensile spring 8.6mm wide to be inserted into submersible fuel hose (one of these can be stretched for 2 installations)
7) 10mm and 14mm sockets and ratchet
8 ) 2 X large flat screwdrivers for fuel hatch removal (thanks jimmy57) or suitable tool
9) Pliers
10) Adjustable monkey grips for fuel clip removal
11) Stanley knife (for old plastic hose cutting)
12) Small flat blade screwdriver
13) Scissors (to cut new gauze)
14) Paint brush and vacuum cleaner (to help remove dust/debris before hatch removal and inside pump housing)
15) 32mm ring spanner or ring socket (to locate pump back onto old gauze filter housing)
16) New fuel filter
17) Spare space for item I forgot to mention haha
Of course I removed the seat cushions first by folding them forward and releasing the red clips. Then I pried on the narrow board between the seat backrests and the luggage boards. There are clips that just require prying here. If you don't have the 7 seat option just lift the luggage board up and slide it closer to the tailgate.
Another important step is to disconnect the battery as the connector to the back seat will trigger an SRS code.
Reassemble the items in reverse order taking care not to pinch any wires around the hatch entrance.

Thanks.
Thanks.

Confession: this was actually done on my 2001 XC70 and I did the same thing on my 2002 XC70 yesterday.
A new revelation has surfaced as I discovered that the gauze filter separates from the plastic housing with some patient prying evenly around the edges. Hence no need for shopping bags
What I didn't expect the second time around was that the pump refused to be tapped out of the fixture.
I finally succeeded by levering it out by prying at the edges of the pump but it was a tough job.

2 weeks and afew hundred kilometres from the fitment and no issues. The car used to ping before the fuel pump repair; no doubt caused by low fuel pressure. Some full acceleration bursts has clean power to the redline. Car gets by on far less throttle and fuel consumption is already less by 2L/100kms on short trips.
I researched some info regarding the OEM Bosch pump that was in the original fixture (0580453447) It is supposedly rated at 110L/hr and 3 bar pressure (around 43psi)
The P80 pumps provided by Bosch (0580314067) are rated at 120L/hr and are also 3 bar (43 psi) so this is effectively an upgrade though I believe the difference is negligible.
