300 Tdi Fuel Lines Which Way

[d2dave]

I have just put another engine(300Tdi) in the old girl. When I took the old one out I failed to note which way round the the fuel lines went on the lift pump.

Can some one please have a caption cook under the bonnet and let me know which one is which?

I have trawled rave and my Haynes manual, to no avail.

IIRC, there may be an arrow on the lift pump(I hope) .. showing direction of flow.
If you can see this, the outlet(ie. arrow out) side goes to the fuel filter inlet side, so by deduction the other line is from the tank .. ie. inlet to the lift pump.

If the arrow was 'inwards' then this would be the line from the tank.

Been many years now, and memory is a bit vague on the exact details of this arrow.

Already looked. Can't see any.

put your finger on one fitting of the pump and give it a tickle with the lift plunger..

if it tries to blow air past your finger, thats out, if it tries to suck it in, thats in.


from there its pretty easy to work out which line on the tank goes where, as one of the lines heads to the filter and from the filter to the injector pump.

I have also tried that with no success. I suspect the pump might be cactus.

At this stage I just want to get it running and I will suss out the pump later.

fit a facet electric pump and power it up off of the fuel cut solenoid

it could also be that the engine has stopped with the pump on lobe which means you dont get any stroke to prime it with.



fit a facet electric pump and power it up off of the fuel cut solenoid is my preferred answer (and I carry a spare for justincase)

When doing a search for original problem I came across a thread about this. Someone suggested that these pumps are not that good for suction and should therefore me fitted closer to the tank.
Is this correct?
Where have you mounted yours?
I assume that you have removed the lift pump and blanked the hole?

Doing a search I have found these pumps to vary greatly in price and there is a variation in pressures.
Examples.

Usually I just fit a lenght of hose around the mech pump and leave it in place but thats because I'm fitting them in the field. In workshop I just cut a 5mm ally plate to size drill 2 holes add sealant and gasket then bolt it up. If you want to mount the pump to that bit of ally, make it out of 10mm and drill and tap to suit the bolt of choice BUT dont drill all the way through or if you do, usel loctite 567/577 to seal the thread.

Oddly, I've never had an issue with these pumps priming any landrover I've fitted them to so long as they are fitted post sedimentor (sometimes filter) AND all the seals are good and tight.

ANy one of the pumps you've put up will do the job, I've got a couple I got from garage sales at something like $2 each that still shift fuel more than well enough for a worked up tdi300

Thanks Dave.

You were on the money about the pump being on the lobe.
I turned the crank a bit and it primed well.

When I first tried it to try and find which way the hoses went, the lever was loose and did nothing,
which made me think the pump was cactus.
