This is a great video and has potentially solved my problem! I have discovered a problem that when my tank gets down to around 1/3rd of a tank, it starts to struggle to start. If I keep the engine going, it will go down to about 1/4 of a tank, a red restricted performance will come up then the car won't start. It is like there is no fuel. When I top up the fuel, it starts with no problem and no restricted performance. I get around this by keeping my tank pretty much full the majority of the time but I think I may investigate further thanks to your video!
Hi, thank you for watching and for your feedback. The electrical connections are always worth cleaning first. The tank pump lifts and recirculates the fuel into the swirl pot creating a suction that transfers fuel across the tanks, the feed / suction / low pressure pump which feeds the fuel filter / high pressure pump is integral / back of, to the high pressure pump. The fuel float situated on the side of the swirl pot as well as the pump itself ( or connections ) can cause problems. Thanks again for watching.
Hi Carolyn, thank you for watching and for your feedback. The video shows how to change the fuel unit as a whole. Check the electrical connections / plugs first ( on the unit ) before replacement as these do break down.
Hi James, thanks for watching and for your feedback. I assume you have the 2.2 diesel. I am not aware of the reason your car needs to go into the dealership but it's always worth checking the electrical connections on the top of the tank / fuel pump unit and inside the tank as these have been known to cause problems. The only extra work the dealership may do is to drain the fuel tank before removing the fuel pump unit. Thanks again for watching.
Hi, the XF 2.2 diesel does not have a fuel sender unit in the second part of the saddle bag fuel tank, it only has a transfer / pick up pipe which connects to the fuel pump / sender unit as shown in the video. What is the problem with your car? perhaps I can help. Many thanks for watching.
Hi Nick, need some advice after watching this video. My jaguar xf 2.2 x250 goes into limp mode and engine light comes on when the tank is quarter full and I accelerate. It can then be hard to start, but works fine again when I put more diesel in and the light goes away over night. I have changed the fuel filter. Would this pump be my problem?
Hi Nanu, thank you for watching and for your feedback. The 2.2 has a different pump, the low pressure pump which feeds the high pressure pump with fuel is integral to the High pressure pump ( fits on the back and should not be seperated ).
Hi, thank you for watching and for your feedback. If the flange is placed and seated correctly then it should lock. What work have you carried out to get to this point?
hi, Thanks for the reply. I was having problems with the fuel gauge. I removed the flange and cleaned the connectors....now it seems to work properly. Having done this I couldn't lock the flange correctly. This morning I went to the Jaguar and they locked it with the specific key. 10 second job
Hi I have a 2013 2.2 xf when the fuel tank is full it leaks if I leave the car parked for a few hours you can see diesel on the road been told it could be the seal on the pump? Any suggestions
Hi John, thank you for watching and for your feedback. How full is full and how long or what does the gauge show when it stops leaking? It could be in the area of the filler tube. I assume the diesel leaked onto the road is underneath the tank ( drivers side )? If so I would take the back seat squab out (as shown in the video), leave it at home, go and fill the tank up, park the car, remove the big plastic grommet ( as shown in video ) and check on top of the tank for leaks. That will rule in or out whether the leak is from there. Don't drive with the grommet removed in case of exhaust gasses. Let me know what you find.
Hi, thanks, We purchased it from a general used parts yard, £70. The issue we had was with the fuel gauge indicator, when full to half a tank no problem, below half a tank it would intermittently register empty causing engine cut-out problems ( computer ? ) when driving ( dangerous on a fast stretch of road or anywhere really ) it was a fuel tank float issue ( part of the pump unit ). The pump itself can be removed from the unit and replaced with a similer pump at a much lesser cost, I would think any diesel in tank fuel pump of the same dimensions would be fine, it would just be a case of adapting the electric plug connection.
@@crystalclearmechanics This is excellent. I'm so glad I found this. I have exactly the same issue in my 2012 XF 2.2D. When the fuel level get's down to around 1/3 full the engine goes into limp mode and almost impossible to start. After turning it over for 30 seconds or so it runs, you get 500m and it goes into limp mode again. My temporary solution over the last 2 years is to top up the tank when it gets to 1/2. It does give a hint it's getting near the limp stage when it takes longer than usual to start. Then I head straight for the fuel pumps. What parts do I need to fix that issue? the complete assembly or pieces?
@@surfonaut Hi thank you for watching and for your feedback. I will explain how the in-tank fuel system works on that car. The unit I take out in the video is called a swirl pot / fuel pump unit etc, the electric pump lifts the fuel up from the tank / swirl pot and under pressure back into the swirl pot, in the process creating a vacuum which syphons the fuel over from the other side of the saddlebag tank. The electric pump / the float and float module can be removed separately from the swirl pot. The low pressure pump which feeds the high pressure pump with fuel from the tank is integral to the high pressure pump ( fits on the back of the cylinder head ). The symtoms were, full to just under half on the fuel gauge , no problem, then the gauge would intermittently drop to empty, if it stayed on empty for longer than ( a guess ) 1 to 2 minutes the car would cut out and not want to start again. Jaguar at the time and the used car parts yard would not sell the float module on it's own so I had to buy the complete unit and chance whether the float module worked ( it did and is still ). It's worth trying Jaguar again in case they have changed their policy. Many thanks again for watching.
@@surfonaut Hi thanks for watching and your feedback, The issue with that car was the float module, symtoms were, gauge full to just under half, no problem, then it would intermittently show empty, if it stayed on the empty for ( a guess ) 1 to 2 minutes then the engine would cut out and be hard to start. The float module is removable as is the fuel pump from the swirl pot / fuel pump unit etc ( the part shown in the video ) but Jaguar and the used car parts yard at the time would not split the unit. It's worth trying Jaguar first as they may have changed their policy. The electric fuel pump lifts the fuel from the tank / swirl pot and injects it back into the swirl pot under pressure whilst creating a vacuum which syphons fuel across the saddlebag tanks. The low pressure fuel pump which transfers fuel from the tank to the high pressure fuel pump via the fuel filter is integral to the high pressure pump which is located on the back of the cylinder head. Many thanks again. If I can help more please ask. P S. The float module is a small black unit 40mm x 55mm x 12mm. with the float attached.
Hi Alex, thanks for watching the video. Yes it is a lift pump.In this case we replaced the complete unit because the fuel gauge would intermittently show empty when the tank was half full, causing the car to loose power and cut out when driving. Thanks again for the feedback.
@Crystal Clear Mechanics I do have problems with an x250 and took the pump out, but the electric pump is sending fuel on the pipe that stays in the tank on removal so I do not see how it is sending fuel towards the fuel filter.
@@aly21xxx Hi Alex, just to clarify . The in-tank fuel pump lifts and recirculates the fuel under pressure to the swirl pot / pump module which creates a suction / syphon that transfers fuel across the tanks. The high pressure pump (located on the back of the engine) has a low pressure integral lift / transfer / suction pump which feeds the high pressure pump from the tank via the fuel filter. The X250 range of cars do have varying fuel systems. What are the problems you have with your car?
Does this fix the XF starting problem which acts like there is no fuel to burn until you try to crank it on the 2nd or 3rd time? Seems to rarely start the first time we press the starter button.
Hi, thank you for watching and for your feedback. When the fuel gauge got down to just under half a tank it would intermittently drop to empty then back too half a tank, if it stayed on empty for to long, the engine would cut out. What is the issue with yours?
Hi, no the fuel will not come on ignition, only when the engine is turning over. The low pressure fuel pump is integral to the high pressure fuel pump ( fits on the back of it and fits at the top rear of the engine ) the low pressure fuel pump sucks the fuel ( when the engine is turning over ) from the fuel tank through the fuel filter then feeds the high pressure pump which in turn feeds the fuel rail and then the injectors. The electric fuel pump that fits in the tank lifts and recirculates the fuel into a swirl pot ( in the tank ) and in doing so creates a vacuum which moves fuel across the saddle bag tanks, it comes on with the ignition but does not feed the engine directly. Tell me the symptoms how the car would not start? @@vvikaaka7496

What size orings and what type did you use for the fuel lines that go into the top?
Hi, thank you for watching and for your feedback. If you want / need to replace the O rings they should be available from the Jaguar main agents.
On that top retainer (green) clip is there also an O-Ring on that fuel line or is it just the clip ? ( 2:02 )
Great video and step by step guide. Does the Jaguar XF 2.2 diesel have the same fuel pump as the Jaguar XF 3.0?
Hi Nanu, thank you for watching and for your feedback. The 2.2 has a different pump, the low pressure pump which feeds the high pressure pump with fuel is integral to the High pressure pump ( fits on the back and should not be seperated ).
