Auxiliary Fuel Tank Saga.

Well it’s been a bit of a marathon but I now have an auxiliary fuel tank fitted to my L/C 60 TD . I bought a 2 year old second hand “Brown Davis” tank that is designed for that model, but because of the vehicle’s after market 3” exhaust pipe the tank had to be modified a couple of times to clear it.
I connected the breather pipes from the aux tank to the breather pipes of the main tank and the filler pipe to the existing filler pipe of the main tank also.

Now promise not to laugh Dave B.

Off to the servo for the big test, the main tank filled as normal then 45 minutes later the aux tank was also full.
167 ltrs all up.
Geeez what’s wrong ---- ¾`s of an hour?
Seems the breather hoses are full of fuel. Huh ???

Next day drained both tanks and removed aux tank filler and breather hoses and with several modifications they now all connect to the main filler pipe above the top level of the highest tank.

I put 100 ltrs back in the tanks then off to the servo again. Bingo, all worked ok.

I have fitted an electronic fuel pump near the aux tank which transfers fuel to the main tank.
This is controlled manually by a switch on the dash powered only while the ignition is on.
This switch also changes the standard fuel gauge from reading the main tank, to reading the aux tank, via a “Normally Closed Relay” thus eliminating the need for a second gauge.

Without a hoist or a pit it wasn’t easy for a bloke of my age and shape rolling underneath about, oh I reckon about 400 + times. LOL

Scrubby.
