in reply to markw: Yes, I just cut off the hard plastic pipes, leaving about 2" behind, slid the fuel hose over this stub and did up the jubilee clip, very tight. I gauged it by looking and tugging but my objective was to pinch the plastic pipe a bit to make sure that the new hose cannot...

I ran two lwnghts of hose from the tank pickup and return to the fuel pump and return lines under the bonnet, bypassing the sedimenter on the way. It ws a while ago now but I think the hose was 8mm bore, it came from halfords, they do not display it but have it available on a roll. I think I...

Sounds like a different problem to me, the one I described is sometimes called "runback" and is to do with fuel from the suction line dribbling back into the tank so the line fills with air, when you start cranking you cannot pressurise the lift pump and air spills into the injector pump, crank...

Fixed. The idler was favourite but once the belts were off it was the water pump that revealed itself as the culprit... What was a real surprise was that although the bearing was truly sha*ged, the pump had not leaked even a drop !! The damage - £130 fitted. Painful, but not ridiculous...

The valve, jubilee clips and a couple of short bits of fuel hose will not cost far from a whole length and from what I have read, a lot of the time the problems are actually attributable to the sedimenter, which would still let your line fill with air, although this should be slurped through...

An update of sorts... I took the car to my local friendly diesel repair garage, where the main man listened for a bout 5 seconds and said : "its probably the alternator idler wheel, I've seen the bottom pulley come loose on one of there, but that sounds like the idler" I left it with him to...

Hi, hoping someone out there can cast a little light on this... 98S 300tdi Discovery, had some starting problems but these were down to runback - fixed with a new fuel hose. That was a few weeks ago - now a new problem. Barely noticeable at idle but very noticeable under power, a whirring...

I had this - perhaps.... Hard to start but eventually it will - 15 seconds of cranking always did the trick. Belch of whits smoke then ran like a watch for the whole day, next time it was left for a few hours though - hard to start again. It was indeed "runback", I'm not sure if it was the...

Well that'll do nicely, small rubber thing, pointy and cross-cut at the end, all blocked up. Pulling it off allowed about a pnit and a half of ice-cold water (not long stopped) to pour out. Top tip: If you do this on a slope make sure you are on the high-side, my a/c had only been turned off...

I have exactly the same problem and am off right now to have a look.
