Thread: Auxiliary Fuel Tank options for 2003 110 Defender

I have a Dolium 45 tank behind rear wheel on mine, it fits between main tank and filler neck, plus a 50l brown davis tank from a Tdi under the floor on drivers side, using a electric lift pump to transfer fuel from that into the main tank. It fills thru a hole under the drivers floor mat.

gives about 1000klm towing the van

Also a 40l stainless water tank on the rear passenger side , and 2 x 100ah AGM under passenger seat to to balance it out.

Hi Andrew,
I have one of these fitted Defender 110 99 ON TD5 TD4 Rep

Fitted it myself over a weekend about 6 years ago and no problems at all.
It is a change over for the factory plastic tank and towing a camper I can still get around 1000 klms to the tank (140L). Clearance is still pretty good, done a fair bit of offroad with it and only knocked it a few times. They seem to be pretty robust units and look like they can handle a few dints.

Sill tanks are an option but I really couldn't be bothered with transfer pumps, wiring and the extra plumbing etc. I guess if you are paying someone else to do it that probably isn't an issue.

Cheers,
Paul.

A few people on here have the LRA 140L tank, including me.

I also have the right hand side sill tank too.

Both are excellent quality and seem to stand the test if time.

However, if I was to install them again I wouldn't use the LRA Sill tank plumbing, the breather isn't big enough so its slow to fill and its a pain to get much more than 40L in it due to the angle I the filler neck. In fairness this has a lot to do with the car design and where the pipe work can be routes. My choice would probably be to fill from the standard TD5 filler and use a Toyota Y shaped pipe behind the filler neck to allow the bowser to be pointed down each pipe. This combined with a bigger breather will sort all the problems.

As for the 140L tank, I've dropped a fully loaded 110 on it more than once. It has a couple of dings in it, but it still holds fuel at all the seams.

I've got the LRA 132l tank in my 09 Puma - reduced capacity from the 140l tank as it retains the rear sway bar. Ultimately I'm
Planning to fit their sill tanks as well (one fuel, one water) and fitted the rear fiestas it was easier/cheaper at the time.

The rank itself is great, but the lowered sway bar mounts not so much - they are now the lowest point on the truck and have copped a real flogging.

If I was doing things over I'd go the sill tanks first, followed by the rear non-sway bar 140l tank.

I have come up with the below findings thus far:

LRA most Popular and available through TJM
All Additional fuel / changes require a Mod plate here in QLD

LRA Replacement 140 lt tank approx.(inc Install) $1650.00 +
fuel. Supply only $1200.00

LRA Aux sill tank under drivers or passengers seat L @ 55lt or R @ 65lt at $1149.00 + install & mod plate.

Dollium rear sill tank - 40 lt approx. $850.00

Brown Davis do a Drivers side aux 80lt tank with the filler neck between rear wheel arch and back door with own fuel gauge and pump to main tank for about $2050.00 installed & mod plated + fuel....

Brown Davis is my preference but for the cost...

Side step may require some modification - I have Heavy duty ones done buy Davis Performance Landys in Amaroo (Sydney).

Hope this is of some help to others..

Still keen to hear others thought and experiences

cheers
Andrew

Yep Mulgo do sill tanks for Puma's and I seem to remember someone doing a calculation a while back that they were the most cost effective $/lt i.e. you get 100lt for around $2k.

Good thing is they keep the weight low and between the axles, you do sacrifice a bit of clearance however this can be offset by fitting portals

Seriously though if your doing touring and not rock climbing your probably not going to notice the clearance loss, I seem to remember the LRA looses a bit of clearance as well.

LRA side tanks do not protrude below the chassis rail ( they are just marginally higher than the lowest part of the chassis rail) and have a 45degree chamfer on the outside edge.

I've never managed to drop the car on the sill tank ...yet
