hiya

thks for the explanation as indeed helps outlining the history of the landy

plus hope the link helped ref testing etc , also ensure the fuel coolers / pipes are clear , never know the in-line tank pump might be covered in slime, inc if it’s been standing for a while

know those in tank pumps aren’t cheap and fingers crossed hasn’t caused damage to the HPFP

If I may also add, make sure the belts and oil pump cover has been replaced

Plse let us know how things go

Hi guys.have checked fuel lines all clear .belts look good I'm trying to get hold of the coloured plastic clips that hold fuel pipes to top of in tank pump.then I can refit tank fill with fresh fuel and bleed system.

hi ,

Hope u don’t think I’m nagging but plse ensure u check on dates of those belts inc the oil pump cover, would just hate if they let go or the oil pump cover snapped

Plse let us know what condition the in tank fuel pump is like

plus of course piccies plse as we all like piccies

Hi guys need some urgent help.ive replaced my old fuel tank and pump for one from 4x4 Kent with pump already installed.have connected this to the car but I've forgot which fuel pipe goes to were.there is a blue cap pipe and a yellow one that go to fuel filter.ive put them on but I'm getting no fuel through or any reading on fuel gauge.but can hear pump when ignition is on.

Without knowing just try swapping them over ans see if that works, if not there is a problem with the pump.
Is there enough diesel in the tank...

Have taken pipes off filter and switched on ignition but got no fuel from either pipe or any reading on fuel gauge car had £20 of diesel in tank .

Double check the connection on the tank electric plug. Sometimes the rubber seal in the plug can stop a positive contact. Also some reproduction parts can differ very slightly and can create a difficult connection, electrically.

Cheers will check.

It's the car on flat ground?

No but have lowered the tank so it is level but still no reading .

Have checked electric plug connector all seems fine gauge still flashing and needle does not move yet on old tank had 1/4 tank of fuel gauge showing.

Lift the sender out of the tank, refit the plug and turn on the the ignition. Then move the sender arm and take a look at the dashboard and see if the gauge moves?

Will give it a go

Have noticed when I turn ignition on the fuel gauge needle does move very slightly to the bottom of the gauge.

Do you need to drop the tank to do the pump? If not, put more fuel into it.
Did you compare both pumps before installing the new one?
Questions questions...

Yes on this model you have to drop tank to get in tank pump out .same fitting and everything same as old pump.

So we have a response from the sender, next is to find out why you have no diesel coming out. Have you tried swapping the pipes?

Sorry not tried sender yet.just that when I turn on ignition the needle moves very slightly to bottom of gauge.

I'm going to try old sender out of old tank and see if gauge moves then I'll have some indication that other sender might be bad !!
