Yes got the rear end jacked up last night and I noticed fuel dripping down I think between the transmission and the fuel tank. What I think is a braided hose was saturated and the pipe its connected to above it was loose - could just move it about - and this pipe led to the tank. I'm thinking it may be the seal to the fuel tank perhaps but don't really know, I guess lifting the back end may have caused fuel to run out. Took some pics and will get them on soon. Would appreciate any help.
Fuel leak, any ideas?

If in doubt replace all the rubber fuel pipes.

Yep.
You simply need to replace the rubber fuel line, because the rubber has gone old and perished, allowing fuel to leak.
Something like this would be a good start

You might be able to get the parts cheaper elsewhere, but if buying from a motor factor, make sure you get 5.6mm inner diameter R7 or R9 grade fuel line (R6 is not good with modern unleaded). The grade will be written on the hose.
What you have on there has a cotton overbraid to the rubber hose. The cotton overbraid isn't necessary, and in fact can hide any problems until the hose has severely perished - so it doesn't matter if what you replace it with is overbraided or not.
Simply clamp the pipe further up (nearer to the tank) to prevent your tank emptying, undo the hose clamps at each end of the rubber piece you're replacing, pull the rubber bit out, and fit the new one, remembering to ensure the fuel hose clips are tightened securely, and that there is a clamp on every join.
This was the fuel line on my bus when I got it... not surprising it smelt of fuel.
If in doubt, it is a good idea to drain the tank fully into a suitable container/containers, and replace ALL of the rubber hoses for new. There should be a metal line which goes through the engine tinware, with a grommet to prevent it rubbing. Make sure you have a good quality fuel filter, preferably fitted above the gearbox (not in the engine bay) and certainly fitted BEFORE the fuel pump, not after.
As an aside, the metal fuel line which goes through into the engine bay should be clipped into a plastic clip on the fanshroud, with the HT leads, like so:
