'Fuel Light' ? Was this fitted to Diesel Landrovers to warn of low fuel ? If so can it be retrofitted or is something built into the tank.
I ask, as my level gauge has a mind of it's own. 

I've got an S3 diesel fuel sender, it has an extra terminal which I was told was for a low fuel warning light ?   I don't use it in Tonka, still running on petrol.

yep diesel fuel sender has two connections one to the gauge, the other goes to a light which comes on when the tank is "low". This is presumably because running out of fuel in a diesel is a pain in the backside compared to a petrol (especially series 1 / 2 with the 2ltr and SU electric pump which is after all the current petrol when the diesel was first introduced)

It's (at least on series 1 diesels) a blue light on the dash, right hand side  above the glow plug light

Diesel powered Series had a low fuel warning light.

The tank sender has an extra terminal (generic tank senders for the late 2As now have this as standard) for the low fuel warning circuit.
The sender activates the warning light when there's about 1 gallon left in the tank.
As the fuel sloshes around the light will flicker on and off.

Easy to retro fit and even add to a petrol tank if you so desire.

The reason diesels got this warning as standard is that to run out of fuel is a right pain bleeding the air out of the fuel system at the side of the road in the dark and freezing rain 
Best practice it to keep the tank with some diesel in at all times.

Bleeding the CAV pump is a right pain whatever the weather. Also that clinging smell of diesel that’s with you for days.

I will have to have a look.

my 63 is a tdi and its a ex mod so it was petrol originally ,

This brings up a question...  why convert over to a diesel engine? Do they provide more power?  Aren't they a bit more complicated to work on?

It's a no brainer, nearly double the mpg! A little slower but with overdrive crusing at 55 mph with another 10 to spare.

No plugs, points, coil and condenser to worry about so less complicated  in maintenance terms.

Just been to mid wales for the weekend with my nephew and some friends.  I had my 58 fitted with a 2.25 diesel aand it returned 29mpg on the road runs and i wasnt hanging about, 750 tyres and overdrive and on the motorway it sat at between 60 and 65.
The only downside is the noise but I am going deaf.

What diesel engine would be best if one were to switch.  Mainly, which would be easiest to swap out without having to modify the current engine bay layout.  Current is the standard 2.25.

I'm biased but recommend a 12J 2.5 hybrid. Apart from drilling crankcase to provide oil feed to timing chain tensioner, all the 2.23 diesel ancillaries fit to 12J block including vertical injection pump and chain driven timing. To all but the most trained eye it looks like OE 2.3 but with smoothness of 5 bearing crank. The fuelling from 2.3 injection pump works fine (did try re-calibrated pump but no better) with no loss of power on hills, with added advantage of much less smoking on startup. You could do this conversion and maintain 2.3 crank but what's the point?

DVLA accepted the slight increase in engine capacity with no loss of historic status and insurance premium remained the same as similar hp.

I've had lots of LRs in the past that have been switched to and fro between Diesel and petrol and vice versa.. at one point it was just pretty much change the details on the log book, but now you'd prob have to drop your Y fronts and jump thru flaming hoops for big brother I'd think...
Personally I loathe Diesel engines, the 2 1/4 petrol is a very nice well sorted engine (imho) and I cannot imagine why anyone would swap it for the Deezle equivalent, but it's as Mr W says with his jar of Marmite !

[Larry S.]

It's just something to ponder.

[genocache]

One thing to know if considering a swap is that the 200TDI heads have not been made for quite a while now. So that makes the 300 more appealing and anything newer will need computer stuff.

Over the years I have owned many Diesel engined vehicles, mostly good occasionally not so.
My Petrol engined IIa ran faultlessly and sounded great. My current IIa was converted to diesel my a PO.
It has a 5 bearing 2.3 Landrover diesel and all be it somewhat noisier, it runs as well as the petrol.
You pays your money and makes your choice !
Happy hunting.
