Thread: long range fuel tanks, good idea?

Hope I don't derail this topic too badly....

I've got 80L LPG scuba tanks in place of original fuel tank and a 45L petrol tank under driver's rear quarter.

Looking at fitting 2 sill tanks for petrol and retaining current setup.

Problem is having to pump from sills to rear quarter at short intervals.

Alternatives might be to run from one of the sills, or to continuously pump and recirculate from sills to rear quarter tank.

Anyone dealt successfully with a similar setup?

Hi.
125l? Tank now a bit dented, plus I'm not sure I want to draw down on the murky last few litres. I suspect the fuel gets pretty hot when very low too. Maybe I'm just over-cautious.
Long Ranger tank directly replaces standard plastic unit. I needed to drill chassis rail and install two extra bolts and tab nuts, supplied in kit which also has instructions, vent lines and other necessary hardware. Fitting kit was available through ARB. My tank was bought second-hand with no hardware.
This tank also has a drain bung, the original didn't.
Pump is direct swap, retained by ring-plate and multiple screws. Its much easier to fit compared with that fiddly plastic nut on factory tank.
Float arm can easily be extended to reach higher tank roof (braze/silver solder) before fitment to recalibrate full level.
I have had it for a few years now, no fitting dramas spring to mind. Very pleased with it. I renewed the pump, seal and the 4 lines as a precaution at the same time.
I certainly agree with Ramblingboy's comment re pricey fuel in remote places, probably helps in avoiding contaminated diesel in some areas too.

I like sill tanks because of the central weight placement. I had them on my RRC and on my County and used a transfer pump to move fuel to the main tank.

You know you miss out on so much , old fellow , by not reading my posts. You obviously have not read my posts in the technical section, in the past. But, hey, live in your world, I'll live in mine. We'll both be happy. EDIT get off my back.

Its a good idea if you need it but unnecessary if you don't
Beats carrying Jerry cans if you need additional fuel.

You're right, Bob, I don't read many of your posts nor Disco Man's as you both mainly post stuff copied off the 'net.

I'd be looking at twin sill tanks, extra weight between the axles, low down, plus you now have 3 seperate storage containers.

Hey, I just purchased twin sill tanks, used, how are these fitted, do you have ideas please?

how you fit them is easy, drill up the mounting points and bolt them in.

but how you fill them and draw from them, well now you have some options to consider.

The setup in my D1 runs a an internal pipe in the filler to an inch Y juntion in the connection to tank piece that then heads to a T juntion down to each tank.

the tank breathers are fitted as a set of 4 3/8 T's into the main tank breather line joiner

fuel is delivered from the sill tanks by one pump each into a pair of 3/8 fittings braised into the top of the main fill joiner pipe above the Y joint so that normal filling does not result in attempting to refil the AUX sill tanks But in the event that the main tank over fills during normal transfer the excess fuel will return into the sill tanks.

even if you dont try to fill from the main filler you must cross link the tanks with a breather so the air from the main tank has somewhere to go and in the event that you overfill the tank you dont wind up trying to blow the seals apart, crack the tank or rupture the internals of the filler cap.

Why did you feel the need to follow me to the D2 section to make that point? What makes you think I care? Mate, this is getting weird, almost like stalking. Please stop.
