Just read the manual on tranferring from sub tank to main, bit shocked to learn it
transfers at 1 to 2 litres a minute. About to fit a 150 sub tank for the big trip next
year, and the way this thing eats petrol, will need it. By my calculations will need
over a hour to transfer 90 litres with the motor running!!! Any one make a tank
that can feed motor directly rather than tranferring [petrol 80 series]

I have a 150 ltr aux tank in my petrol 80. Transfer is never a problem. I normally don't wait until the main is way down and transfer when it gets to about 1/2. Just do it on the run - if I recall the manual says you should be stationary but thats BS because I've never had a problem since buying it (about 6 years ago).

Same as DOZER.

I've had my manual petrol 80 for 6 years, and have ALWAYS switched fuel across while on the move (why would I sit in an idling car while waiting for the fuel to transfer?). I have a 180l long range tank in place of the 50l one.

Even travelling at 110km/h - and with the manual gearing it's pulling around 2800rpm, so chewing through fuel faster than an auto would - the transfer more than keeps up and shuts down when the main tank reaches 2/3s full.

I prefer the way the petrol unit feeds from the sub tank into the main tank rather than sucking the petrol from the sub tank straight to the engine. Without having spent the extra on putting in new sender units, etc., to take into account the new capacity of the LR tank, it's easier to see how much is left in the main tank after transferring from the sub-tank (though after a while you know how far 2 full tanks - 275 litres - will get you depending on driving conditions).
