I came up with a solution to my twin fuel tank dilemma - sort of. I found a bunch of listings for 'dual fuel tank switching valve' and they all appear to be either 3 port (one in/two out) or 6 port (same - doubled up). The vast majority of the 3 port valves are identical (they look like copies of Ford and GM OEM fuel tank selector valves) and the prices can be vastly different (from $25ish USD to $50ish USD) but as always the freight is brutal. It will eliminate the need for 2 pumps, should simplify the install but the part is specified for a non-return line fuel system and the selector valve must be installed with filters into both inlet ports from the tank - that means the pump must be installed in the main fuel line after the selector valve. Not ideal with an electric fuel pump.

geezer, I 1st became aware of a fuel tank switch at GSA Auctions of a 1983 Chevrolet Truck (it needed it replaced in the auction write-up) internet images of this type truck showed the switch located about center of the dash... https://gsaauctions.gov/gsaauctions/aucbdcls/

I searched for: "fuel tank switch" within the results of a list of "Closed Auctions" At the GSA Auctions home page, click on "Browse by Status" then click on "Closed Auctions" this will show 2 years of auction history... You will see the aforementioned 1983 Chevy truck on this list...

LOOK at this link, it explains the Chevrolet Fuel Switch systems: http://67-72chevytrucks.com/vboard/s...d.php?t=754061

Ya think Australia is big enough for two fuel tanks (?) without driving off the other side..?

I'd like to use the factory style dash switches that are available on ebay as part of this install (I'll put it in the centre console if it happens). The dual fuel set up in GM/Ford trucks are a main + auxiliary tank? Some of the control systems utilise the fuel level as a trigger to swap over the tanks (I'm going to opt for a manual override) To give you an idea of what travel time from city to city in Oz is like - Adelaide to Melbourne is 8/8.5 hours via road non stop. That is the nearest capital city from my home town. The main reason why I'd want to add a tank is the cost in fuel spikes. We are now paying $1.70ish AUD/Litre at peak price. On the low side of the pricing cycle it isn't going lower than $1.29/L. And I like having an ace or 2 up my sleeve. Thanks for the links xboxrox
