Tdi 300 lift pumps?

[sumo]

Hi all.

Have heard the lift pumps on the 300 tdi are a bit vunerable, mines done about 150,000ks, should i replace as a precautionary measure.?

THanks Sumo. :?

My TDI has done 157000k's and it failed as I drove into Rover park last weekend. It stops the car dead in its tracks no warning.

So if you want my advice " change it " while your TDI is still going rather than when it stops.

do a search on the tech forum, it's been discussed pretty well. :wink:

From my limited experience (happened to me once) the lift pump failing only becomes an issue when the fuel filter is changed.

The diaphragm fails and the primer lever on the lifter pump doesn't work.

Normally the system has enough ooomph (a technical term) to draw the fuel through but when you break the line by replacing the filter there is an an air gap that can't be primed.

I reckon that if I had left the bleeding screw open and the engine turning that this would have bled itself.

So....wait till it fails.

If you're worried, get a replacement, about $75 from Karcraft, get a couple of olives at the same time. Print out the instructions from your rave manual. Stick 'em somewhere in the truck, forget about it. Replacing the lift pump isn't difficult, it's just a pain in the arse - about an hour.

As OI said, the time you're going to pierce the diaphragm on the lift pump is when you prime the pump from replacing the fuel filter, or running it dry.

One of our members removed the pump completely....and used a Cav Fuel filter replacement with a priming lever :roll: :

As Rick130 suggests a search using "lift AND pump" will reveal a mere two pages of topics.

Note the olives.. and I am not talking Kalamata :wink: .

Yes there is a couple of different options you could use, but for us stranded on the side of a dirt road in Rover pk 4pm on a Friday afternoon we took what we could get.

My Tdi lifter pump failure was only apparent when the fuel filter was changed...The diaphragm had failed some time previously without issue.

The stoppage of yours is a matter of forensic conjecture :wink: https://www.aulro.com/afvb/

It was a combination of 2 things that ended up getting it going, there is 1 wire that runs to like a shut of valve/pump and when that wire has a break in it or poor conection it is just like turning your ignition off ( no go )

We also had to replace this to fire it up again, but the pump was also a problem as we discoverd once removed. :roll:

Landrovers can be a hassle at times :wink:

Hi, i had to replace my lift pump in october 04, and not because of a fault with the pump itself.

The problem arises because the fuel line going from the top of the fuel filter assembly to the lift pump isnt quite long enough. As a result over time it stresses the nozzle that comes out of the lift pump and over time it leaks diesel everywhere. If yours is fine, mine had done 165000km when it happened, and it seems the harder the engine works the quicker the leak develops, take the line off, measure the length add 10cm to it and go to pirtex with the fittings and get some flexible rubber fuel line. Since doing that i havent had a single problem. Thats the main problem associated, i havent heard of any others. If you are that worries they arent overly big buy a spare one and a gasket keep it in the back of the car they only take 20mins to change. Matt

That's usually what happens on the 1st major service just outside of the warranty period. The customers are really impressed :? .
The injector pump has enough in it to draw fuel from the tank, but it won't suck enough once air is in the system.
