Managed to get the caravelle's fuel tank out this afternoon. Not as bad as i was expecting really.
One corner up on a ramp as the tank outlet is on the rear right corner of the tank. Only about a litre of fuel came out.
Filler cap and hose removed.
Both expension tanks disconnected. They're staying in place as they were a bugger to get back in when i removed them last.
The 2 M8 bolts undone and the support straps remove and the tank was out. Not as crispy on the top as i was expecting, though the two breather pipes are rotten as anything. Sender unit and most of the top of the tank was covered in an inch of mud.
There was still about 5 litres left in the tank which had to be tipped out of the filler hole into a drain pan.
Big empty space where the tank once sat.
Gonna clean it all up in there before i install the new tank. Not sure whether to give it all a spray of waxoyl or similar beforehand.
