Rick Many thanks for that one, its just what I wanted to find. It actually seems to make the task quite simple.
I wasn't trying to reinvent the wheel, just to be able to do my regular Cork Dublin trip on one tank of juice by adding extra range using fairly standard components. It does seem quite simple and also makes one task easier, a more accessible fuel pump and fuel filter.
In essence what is there now is to take the original flow connection from the Ks tank back to the auxiliary tank as a gravity supply in. The return fuel line still remains in its original position unaltered. That looks to be as simple as changing one fuel line by inserting the tank into the fuel supply line with a pumped supply from the new tank to the original fuel rail position. The return line remains unaltered.
On the electrics I plan to leave the 7 and 4 litre warnings unaltered. That will give me a 9 litre warning on the red. I can intersect the fuel pump electrics at the relay and route them to the new pump.
The only other thing is to sort the cut off solenoids and that seems quite straightforward, although I would like to take it from the fuel pump relay so they are both on the one circuit.
Making the tank is an easy part. I have checked that out and asked a fabricator who said if he is given a drawing or a full size mock up he will make one for very small money. The easiest way of working it out is of course a mock up made out of insulation as its possible to work out getting it in and out if necessary. The removable panel can be on top so that its not necessary to remove the tank to access the pump or filter.
Duck we do have some of those card pumps here too but not many. The problem we have is the absence of the petrol stations in the first place. In Europe most cars are diesel and have ranges of 500-700 or more miles on one tank of diesel and comfortably overcome this. Everything in the US seems to run on petrol/gas and have small ranges so you have plenty of gas stations. Some cars in the US struggle to do 150 miles on a tank of gas. But in parts of our county you can easily be 80 miles from an open petrol station at night.
