The big question for me was why did LR not fit a water trap between the fuel tank and filter housing or incorporate a water bowl into the OEM filter housing?
Recently my mates 07 Puma developed a fault as if it was suffering from fuel starvation. Did the usual checks looking for DTC's, changed the fuel filter, blocked breathers, crimped/broken fuel lines all coming up clean. In the end I removed the fuel feed from the tank at the filter housing and found crud blocking the inlet port. It looked like paint flakes and tiny bits of swarf which I took came from the forecourt pumps? Cleaned all this out and bled the fuel lines and he has had no issues with it since. First use of the LR bleed tool and it does work, but very expensive for what it is, should have just made one as per the post from AndrewS 
http://www.spxtools-shop.com/jlr/product_i...12828.html So because of that and the lack of a water trap I have decided to fit an additional fuel/water trap between the tank and filter using the Raccor RA230 combined filter water trap. The thing is that now I have found a company that supplies add on water bowls to the OEM filter using the drain screw as the mount. I have ordered a new filter and water bowl from them and hopefully should get it fitted this weekend. I have concerns about using the Raccor filter in that it is another restriction to the fuel feed system for the low pressure transfer pump to deal with. The transfer pump operates at between -30 and -20 kpa when new, so over a period of time and wear I am not sure it would have the pull to draw through two filters and could lead to fuel starvation/runnng issues. Saying that I bought the raccor unit so I may as well fit that too as there is still the issue of possible crud from the tank blocking the OEM filters inlet port. 
The add on water trap will probably lead me to alter the filters shield in order to get it to fit, but you never know it may fit first time, then again when has anything been easy on a defender? The raccor unit is available from http://www.euro4x4parts.com/parts/frp1005-...ra230.html And the neccessary fittings from http://www.euro4x4parts.com/parts/f/prefil...ssories/1/ This is the filter, WJI500040 for the 2.4 and the water trap screws onto the bottom using the filters original drain screw. Point to note was that with the bowl fitted you have the normal water storage of the filter plus what the bowl holds. Also it should give a good visual indication of water contamination whereas before the only way to know for sure was to drain off the filter. I contacted them yesterday before I ordered the new filter bowl to check they where compatible and was assured it is a straight fit onto any OEM filter with the water drain plug. The filters this company supplies are from the same manufacturers of the OEM filters but without the expensive LR badge and green paint.  Click image to enlarge and the water trap

lorryman100
thanks for the information - always interesting / useful to read. can you confirm if there were any fault codes and was the fuel starvation intermittent?  |

Do Land Rover not supply a sedimentor as an option any more then?
They always used to. |

Dear Lorryman!
Thank you for sharing such useful info! I thought about water in diesel problems before but there were no simple solutions. Today I bought water collection bowl from your link. Cheers! Puma 110 |

There where no fuel related dtc's logged in the EMS. In hindsight though P2635-07 should have been logged? P2635-07 Fuel pump , low flow performance, Fuel supply pump, Insufficient flow. I was initially thinking it was a fuel pump pressure regulator fault. But thankfully the relevant dtc's were not present for that fault, P0091-12, P0091-11, P0092-11 and P0092-12 would have meant a new pump! The fault was intermittent, so much so it was getting worse each time it happened. As the crud was solid and not sludge the fuel was getting to the filter, but not full flow all the time. I suspect it was crud from the bottom of a forecourt tank that introduced the contaminants but jerry cans used by a previous owner could also be the culprit? Brian. |

I don't know the answer to that yet? But I should be able to alter or fabricate a new cover if the need arises.

How do you know its starved of fuel? Did you get dtc P2365 logged in the EMS? Any other dtc's logged? There are 4 quick release couplings on the filter housing. The two on the tank side are the feed and tank return pipes. Undo the tank feed and check the port for crud. You may need to bleed the fuel system if you remove it, I did bleed the system but I am not 100% sure I needed too? I was going to strip the filter housing down and use an airline to clear it, but there is a thermostatic diverter valve and I did not want to risk damaging it incase it stuck open allowing fuel above 45c to enter the plastic fuel tank from the fuel cooler.

No probs Denis as that is what forums are for, to share knowledge and experience in the hope of helping others.
ps, I hope it fits now and I haven't given you all a bum steer.

yes lorryman i did have 4 different codes cant remeber what they were now but it basically ment that each injector was being starved of fuel
so this could be the answer regards steve 2015 2.2 tdci hardtop xs 3.2 conversion DONE 238bhp and 707nm torque and thats just the start ;-P hybrid turbo in build -done ready to fit ashcroft atb in transfer box 6 speed auto in build |
