Thread: Disco Td5 new fuel pump

Is there a preference for any particular brand? Any help would be greatly appreciated.

Check the relay that controls it maybe the connections are corroded or the relay has died
Much cheaper if it is the case also better than replacing the pump to discover it still doesnt work

+1 for the above, first of all make sure it gets feed, if you'll need a pump the best is VDO but it's expensive, cheaper aftermarkets are lottery but can be even a winner depends on luck

Thanks guys, makes sense. Will check!

AFAIK it is best to buy the full assembly and VDO is the preferred brand. I was lucky to get one on special from LR Direct in UK.
I have seen it reported on here that it is also best to get a new gasket. The pump is held in by a big plastic "nut" for which there is a special tool but you can get away with a big screwdriver and hammer if very careful.

You probably know that there is a porthole in the boot floor for access. I found it best/easiest to cut the carpet with a box cutter under the side bins rather than remove everything. You can then roll up the carpet from the back after removing the trim strip.
The hoses are removed by pressing in the buttons and pushing forward then back. I found it best to bend the arms of an offset pair of small needle nosed pliers to push in the buttons.

You've all been most helpful, thank you.

By the way, does anyone here have the specs for the fuel pump itself, ie. pressure and lpm? It could help to cure reliability issues to know what the equivalent Walbro pump is. Not to mention the massive cost saving it would be to just swap out the pump for what is a more reliable unit.

Relays and fuses all checked out so conclude that the pump has died. Have ordered a VDO from LR Direct. They were by far the cheapest, even allowing for shipping from the U.K.

It is not so simple Grasshopper.

The pump is actually 2 pumps , a low pressure pump which feeds into the filter which then feeds back into the high pressure pump which then goes to the engine.
I don't think you will fin a Walbro equivalent.
