Thread: lpg sill tanks for a 110

I don't think that you could connect them to the floor and it wouldn't be safe connecting to both the floor and the chassis as they would move at different rates in a severe impact, and then something would be sure to break - having been in a head on impact in a Land Rover I can attest to that.

On the SIII I had to remove the outrigger that supports the original fuel tank, the body panel (behind the seats) was stiffened with chequer plate alum. and it's worked fine. The Defender has more space than the SIII as it doesn't have the outrigger.

I got my tanks from an F100, they look like forklift tanks and some people ask if I store BBQ gas there, but they are stamped with an automotive complicance no. If you get tanks that don't have the end caps like the ones in Rons pics, make sure you cap them somehow. I've had several instances of mud building up and breaking the earth safety solenoid cut-off wire. An easy repair, but inconvenient in rain and thick mud. Normally I just switched to petrol till I got a more opportune time to repair it, but that cost more.

any pics ?

What do you think?

You're better off putting the scuba tanks in the back that replace the main fuel tank. That will give you 70-80 litres usable LPG. Then a 35 - 40 litre tank in the rear quarter panel and a couple of sill tanks for petrol. The sill tanks also make good rock sliders and are a good jacking point for air jacks.

Each sill tank will give you about 35 litres. So you will get 80 litres LPG and just over 100 litres ULP.

The fuel pump and gauge go in the quarter panel tank, an electric fuel pump bolted to the chassis draws fuel from the sub tanks and refills your rear tank.

I've used 2 x 2-way switches for the fuel transfer.

Switch 1 switches the pump on / off
Switch 2 switches a solenoid tap right or left pick up. I got the solenoid tap from Brown Davies in Bayswater for $70 and I used a fuel pump from an early Rangie which can pick up and push. I got it from Range Rov in Mitcham for about $70.

Be sure to put a disposable in-line filter between each tank & the pump.

My tanks fill from the rear wheel arches. Pipe hoses and screw on fuel caps and fillers came from Purple Pig in Bayswater (about $25 per side).

It's difficult to refuel when the Rangie is loaded for a big trip as the wheel arch clearance drops and make it harder to fit my arm in there. Also service station pumps aerate and squirt the fuel and it sometimes squirts back. Resting a jerry can on the tailgate & filling with a super siphon is a lot easier and I can get more fuel in due to decreased splashing.

For most trips though you can just fill them with the car empty and then pack it and you'll have enough fuel (180 litres combined ULP & LPG). For road trips, a 2" lift would definately make it easier to refuel.
