Ok, I needed a tank. I considered having one made of stainless steel like Luke did, but while running through ads on the net, I found a very nice tank. It's a polyethylene tank designed for use in boats. It's dimensions are ideal, it has the right connections. Outlet, Return, Breather and fillerneck. It also came equipped with a sender unit. The sender speaks a language the Scorpio's fuel gauge understands, so I was very happy with that. It's pretty accurate too.
The capacity is 49 liters, that is less than the original 68, but I can live with that, because the new engine will have better MPG than the old one.
The tank was a real bargain and only a 15 km ride from my home. I paid only 100 euro for it!Most new cars have tanks made of this stuff and it feels very solid. This is the tank:

The only problem with this tank is the width of the filler neck. It's 38mm(1,5inch) and the car's filler tube is 51mm(2Inch). I ordered an adapter hose for this. Now I had a new problem. The original filler pipe exits in front of the rear wheel, goes underneith a chassis crossmember and enters the original tank in it's flank. The new tank however must be entered from the top. This ment changing the spot the filler pipe exits the car, because the tank could not be lowered enough to use the old connections. I changed it and it now exits right above the tank's fillerneck.

I modified the original tankstraps, added some rubber padding and there it is:

The new tank is longer , so I had to change the position of the pump and mounted it to the floor so it clears the tank. You see, everytime you make a change there's a lot of other things that have to be altered too
