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:
