Fitting a TD5 Auxiliary fuel tank into a TDI 90

I have recently completed this myself and have written a thread on how to do it to help others as this info is very time consuming to find and hard to come by. I have posted it here:

I hope this is helpfull to those who need extra mileage for their 90. Mainly those travelling overland where fuel points can be quite far apart.

Enjoy

Very Nice Job ! Unfortunately that is significantly outside my skills/tools set It would cost a fortune to pay someone to do that for me, probably cheaper for me to buy an aftermarket bolt on tank...

You would only need someone to weld together the bracket. If you sourced and cut the metal, you could hand it over to someone to weld. Likewise with the Filler. Its not that difficult honest

I haven't read it all yet but something come to mind.

If I'm right in thinking the fuel tank on a 90 behind the drivers seat/underneath body.

If thats correct and presuming that where you have mounted the new tank is slightly higher up then why have a transfer pump?

A tractor we had on the farm had two tanks, one under the cab from which the engine took it's fuel, and another above the engine. The bottom tank was gravity fed from the top tank, couldn't this be possible with your installation?

Hi P.

Not had a good look, but I think a large percentage of the tank is level or lower. The original tank is predominantly above the chassis rails while the TD5 tank is predominantly below the chassis rail.

I would love to that my only concern is that it don't half sit low behind the crossmember. Where else can I get long range tanks from? matt savage?

Nice job tho, it must be said neat and tidy like it.

Its not as low as it looks. Its the same as a TD5. There is a little more room ontop as its not completely snug, but only 1cm or so.

you can have a look during the indoor 4x4 show if my 90 gets chosen

Cool well I was scraping my rear cross member in Derbyshire doing chapplegate but if its only 10mm or so i guess its not that bad couldn't bare the thought of money dripping from my fuel tank. that would mean less time driving the damn thing!

If he was on a slope, then the rear tank could surly end up much lower than the main regardless? Im thinking of fitting my jaguars fuel tank to my defender, and use its current fuel pump to transfer the fuel to the main when required.

Safari Equip has the best selection I have seen, they do a rear and a left side for the 90, 48l and 40l if I remember right.

Another reason for not having flow through tanks is that you can keep your tanks separate, so if you pick up a tank of contaminated diesel, you can dump it and use your aux tank to refil the main.

cheers booger guess I need to start selling my refurbed Diffs Pretty quick to get some dosh for all these goodies.

As an alternative to using a Y piece for the fuel filler, I fitted a second proper fuel filler at the rear in the place a TD5 normally has it - hobson industries were selling off a bunch of TD5 filler necks/caps etc a while ago for about 15 quid.
I rigged mine up to pump fuel from the TD5 tank into the main when I was running low - I need to make a larger vent on the main tank though as those TD5 pumps can transfer a lot of fuel quite quickly - I blew the fuel cap off the main tank once with the pressure!

Hi 8pot seen your posts on other forum's, welcome to Landyzone. I will be ditching the Y piece shortly and replacing with a dedicated filler. The Y piece requires a fair amount of fuel hose and is not so neat. Just waiting to source the TD5 filler bits. Do you have a pic of yours? how did you cut the Tub?

I think im giving up on my axuillery tank. it fits perfectly on top of the wheel arch, even slots under the curve of the body work, and has a pump in it to pump the fuel to the main. But i cant secure it in any way that would even begin to hold it there in a crash, all i can realy do it box in into the bodywork. 80kg of diesel loose in the cab, not good.

diesel IN the cab is not good for a start. Thats why I went down this route, so I could shift the 2 jerry cans from the load space, lose the smell and gain the space.

As much as it would technicly be in the cab, fumes wouldent be an issue, would box it into the body with sheet steel and put vents in the exhisting wing floor. The filler would be a hole in the wing same as the regular one, i have all the fittings off the jag to do that.

I want to do this and I have a tank but it hangs down sooo much

stick a guard over it. I haven't clubbed mine yet. Like I said, its no different to a standard TD5 set-up.
