Thread: 300 Tdi Fuel Lift Pump

I just did one on Dads because it cracked around one of pipes. M.R automotive sold him OME unit and gave him the olives and nuts at the same time, I think it was $110 or so.

300tdi fuel pump in disco leaked around the compression seal for the diapragm, after I picked myself up off the floor with the price, I had a good look at the injector pump. This is the same VE bosch that we have on a tractor at my cousins property. Guess what?, it doesn't run a lift pump. So I have removed the lift pump altogether, used a piece of stainless steel as a blank off and rerouted the fuel line into a Fleetguard fuel filter with manual primer pump (uses CAV296 filter, $25 2nd hand). Runs like a charm and has done for the last 20 odd thou. So this begs the question, why did Land Rover put this fuel pump on, when it appears that it is not needed in the first place?? There is no loss in power, appears to get even better MPG and does not run out of fuel at maximum boost and revs. So dont't replace it, remove it!!!

That's interesting.

I guess once the system is primed it is self perpetuating.

When this one fails I'll try the no replacement path. [img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img]

Just a warning for those using an after market job. Make sure the shape of the unit doesn't interfere with the fuel lines from the injector pump to the head. It wont fit if it does. There are subtle differences between early and later model 300Tdi's.

Very interesting, how does the lack of mechanical priming pump handle low fuel tank levels?? Or is gravity enough to let the feul through??

If it works sounds like a good retro fit!

Shifter.

Same thing happened on my brothers disco, cracked around the inlet on the pump, if you have to replace the pump, look at lengthening the line from the fuel filter to the pump. On the 96 disco the fuel filter is mounted on the firewall and the line to the lift pump (on the motor) is short and tight, putting stress on the fitting.

So lengthen the line from the filter to the lift pump to stop it happening again!!

Cheers

Land Rover issued a modified hose under #WJP108350 for that problem. Seems to affect some cars more than others - most unusual for Land Rover [/sarcastic remark] :? .

***Just checked the price - $142 list :x . I think you'd be beter off having a hose made to suit.

Thats more than the pump.

Would that be a surprise? :?

Actually, if you bought the pump from LR, then the hose would be cheaper than the pump (by about $30) 8O .
