Improved Sub Tank fuel recovery

[Rip'n'Shred]

Great idea, providing the transfer pump cuts out before the tank is empty. I suppose that's why there is so much left in aux tank from factory, ensuring fuel remaining despite angles.

Fuel tanks are designed to leave around 10% in thew bottom of the tank for Condensate (water) to accumulate and the sludge and grit to sit.
They also fit a fairly fine plastic strainer on to the fuel pick up to hopefully stop the grit and sludge (leave it in the tank), however I've had issues with the in tank strainer blocking and having major issues with lost power.
So I have removed the in tank strainer and fitted the hose extension in order to get all the fuel, I then fit a in line strainer and seperator in the fuel line before the OEM filter
I did this in 1996 to my 1992 Hilux and have not had to change the OEM filter since, (200,000 km+)
I have now done the same to my Tractor, Pajero and Patrol
I don't like fixing blocked in tank strainers on the run much easier to clean a External seperator and in spect the in line disposable strainer every 5,000km

I wait till the Main tank is <1/2 full, then start fuel transfer, when the maintank stops rising and Sub stops falling I then press the Sub button again and the pump stops.
The sub pump is a self priming diagragham pump and designed to run dry for short periods.

Good job on getting more out of the sub tank. The extra filters are a good precaution.

Nice idea, will have a look this weekend at mine. Will defintitely be putting a filter sepeartor on when I get the car back running.

Just filled up
ran sub out and main to warning light
then fueled up 120L, and 970km, so average 12.3 L/100
Happy with that
