ciderman Posted December 19, 2006 Share Posted December 19, 2006 The electric fuel pump in the tank has started to get louder on the company Defender . Is this common on these to wear after 50k , M,J Fews want over£200 for a new one and wanted to be sure before buying a new one . Cheers in advance Jase.

BogMonster Posted December 19, 2006 Share Posted December 19, 2006 They go pop quite often, loud "who stepped on the cat" whining noise usually means its time to budget for a new one sooner rather than later, and they are a pain in the butt to change because you have to drop the fuel tank, unlike a Discovery where there is a sensible hatch under the rear carpet. Which is what any Td5 Defender I owned would also have after the first pump You could leave it till it goes it might last a year or two or it might last another week - Sods law of course it will break at the most inconvenient moment so the decision is yours Quote Link to comment Share on other sites More sharing options...

dirtydiesel Posted December 20, 2006 Share Posted December 20, 2006 They also whine very loudly if there's an air leak into the system. The push fit conectors on the fuel lines sometimes can cause this, as can a damaged fuel filter head. Also i've come across head porosity allowing combustion pressure into the fuel line in the head, which in turn air locked the pump. But it could just be the fuel pump on it's way out.

JimAttrill Posted December 20, 2006 Share Posted December 20, 2006 I am wondering when a pirate part maker will start making the pump only, rather than having to buy the whole shebang complete with fuel level float etc. Re your pump only lasting 50k, the way to destroy a pump very quickly is to run out of fuel. The pump does not like this at all. We had a TD5 in the workshop a week ago that would start and run even though the pump was not running at all. But it wouldn't rev much above 2500 rpm. I was surprised that it would even start. Quote Link to comment Share on other sites More sharing options...
Petergg Posted December 20, 2006 Share Posted December 20, 2006 Mine started whining 3 yrs ago, I carry a spare with me got ot off ebay £70ish. I have made a hatch so can change it when need to. Peter Quote Link to comment Share on other sites More sharing options...

They do run as long as no air gets into the system but you're lucky to get up anything resembling a hill without needing low range Quote Link to comment Share on other sites More sharing options...
Steve 90 Posted December 20, 2006 Share Posted December 20, 2006 Jase we have fitted loads of them, Sometimes the impellar come's loose so they loose preasure and other time's they get noisey and can keep going for a while till they stop. Could be 3 years, could be 3 days. The only sure thing is one day it will stop so may as well bite the bullet and put one in, Save getting stuck somewhere when it does go. The early one's were real bad, the later one's seem a bit more reliable but still not great. There are actually two pumps in that unit. A low presure one that pumps fuel up to the filter head then back to the pump wher another pump then pushes the fuel forward to the pressure reg on the head at a second higher pressure so it aint as straight forward as just fitting a pump the the fuel tank unit which is probably why none of the fuel parts type companys have produced a replacement yet. When you refit it you can make the pump "purge" the system by turning the ignition to the second possition then pressing the accelerator right to the floor and releasing it 5 or 6 time's. The Engine management light will then start to flash and the pump will run. Leave it run till you hear a noticable change in the sound of the pump (1-2minutes) then you should be able to start the engine! Quote Link to comment Share on other sites More sharing options...
ciderman Posted December 20, 2006 Author Share Posted December 20, 2006 New pump on order , Thanks again for the info . Quote Link to comment Share on other sites More sharing options...
BogMonster Posted December 21, 2006 Share Posted December 21, 2006 The early one's were real bad, the later one's seem a bit more reliable but still not great. Absolutely true. We fitted loads of pumps (and injectors and ECUs) under warranty in the early days of the Td5s but the later engines seem to be much more reliable on all three parts, they do still go though. A bit like the injector harnesses, whatever the "official" version is Quote Link to comment Share on other sites More sharing options...
