Outer Limits 4x4 Board

i have just bought a aux tank for my patrol. i want to run both tanks seperately, (eg. not pump the fuel from the aux into the main)

i have found these pollak 6 port valves http://pollak.thomasnet.com/viewitem...lve?&forward=1
has any one used one of these before or something similar, my concern is that it says its suitable for intank fuel pumps, which being a deisel mine is not.

am i onto the right sort of thing or am i barking up the wrong tree??

any help on this topic would be great.

link not work


i have used a 6 port on many occasions some were suction others were pressure fed and it made no difference it should work the way u want
got my valves from tjm and longranger tanks

I have run them in a number of vehicles and the Army run them in their Land Rover variants with dual tanks.

I ran two on my Cruiser most recently and both expired due to water ingress to the electric motor that runs the worm drive for changeover (which is vented to atmosphere.) I had previously not encountered such problems with other setups but the cruiser mounting was lower and I did a lot more wading with it.

Either mount it high and dry or use the Cruiser type which are sealed (but expensive).

It should work for what you want to do.
However I just pump to the main using an electric fuel pump and filter, made more sense to me as that way i can totally pump the sub tank out - with a 6 port it would start starving for fuel long before the sub was empty (being a gq with the long subtank and pickup at the back) unless you were heading up hill for the last 10 litres or so.
Wouldn't matter so much on a petrol, wait for it to noticeably start surging and change it over (like a bike with reserve) but on a diesel that'd mean air in the system.
Weighed up the advantages of each and couldn't see much in favour of the valve?
