Thread: lpg sill tanks for a 110

Sill tanks are normally for petrol.
Do you mean the scuba tanks between the chassis rails at the rear (instead of a petrol tank)?

yes, along those lines. are they fixed to the chasis/floor pan or both? are those tanks for LPG?

Chassis, I think. I can ask tomorrow. They are LPG tanks on an LPG fumigation vehicle. I took some pics but not from underneath. It was in the workshop about 2 weeks ago, I could have snapped as many as needed.

I grabbed thoes pics off the DieselGas website

I clamped some similar sized (2 x 35litre) tanks to my SIII (1 per side). I clamped the brackets to the chassis and the LPG installer certified the install (he ran all the pipes etc).

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.

Well there you go.
Never seen anything like that before.

I wouldnt be putting tanks there, just a bit to close to the ground and just waiting to be hit, i am suprised they would be legal.

They're higher than the chassis, and I've put a broader skid / bash plate on mine. The only times the bash plate has been hit is with ramp over issues, but then the chassis has stopped any further impedence anyway. The original fuel tanks sit a little lower than that anyway.

I agree, it doesn't look like an ideal set up, but it's a lot more protected than I would have imagined, and it keeps the LPG out of the vehicle. My SIII carries a s/wagon rear tank and 70 litres (usable) of LPG without compromising interior space or ground clearance.
