Thread: Fuel Tank Question.

Some people use exactly the same (standard) sender in the LHS tank, and then simply switch from RHS<>LHS and wire it up accordingly.

Others have an entirely separate fuel gauge.

Others just pump from the LHS tank into the RHS tank.

As above.

My 2a has the switch to change gauges, my 110 has a separate gauge.

Probably a tossup which is preferable. I regularly use both vehicles and have come to no definite conclusion!

The 110 did not have a gauge for the second tank when I got it, but I fitted one soon after - you really don't want to have no gauge, especially in a diesel!

The Lightweight LandRover has a gauge changeover switch combined with the petrol tank selector switch, when you change tanks the gauge automatically reflects the correct tank. You might be lucky enough to find one on eBay , I think I gave mine away when I sold the tanks after converting to EV.

That will be what is shown in the Optional Equipment Parts book - I have never seen one!

Easy enough to wire a switch to change over the fuel gauge and fuel pump to the second tank 👍. Can whip a drawing for you if you need some assistance here. New sender and pump required for second tank - you can use the same type as the main tank has.

I’ve gone slightly different in my Sons series 3 we are building - have only one sender and I have it so the second tank pumps into the first tank keeping it full and the overflow returns back to the second tank via a seperate line I installed. Not everyone’s cup of tea but it works - also have a filler on both sides that fills both tanks. Can pull up to either side of a pump at a servo and fill both tanks.

My Series I has an additional fuel tank under the rear floor.
There is a switch to change between each tank and it switches to the appropriate sender.

My Defender has a sill tank, you pump from the sill tank to the main tank. A three position switch shows main tank, sill tank or main tank and operate transfer pump. There is also a low level sensor in the sill tank so if you pump too low the pump switches off.

My Series II GS has two tanks and a changeover tap to switch between them.

Does your second tank have a hole for the sender in it (maybe blanked off) ? If no then pumping to the tank with the sender may be an option but you need to try not to empty the tank and run the pump dry.

heres one

I have 2 tanks under each front seat Rh and Lh and a rear fuel tank. I have the same fuel switches as the picture in the previous post. I'll have to check to see it they have sensors. I just assumed you ran them until they were empty and that I only had a sensor in the rear.

I haven't got the Landy on the road yet so I haven't had any reason to fill the auxiliary tanks as yet.
