On my Sylva Star it uses a Vauxhall Viva fuel tank, The outlet pipe seems blocked - I have blown compressed air down to no avail
May question is - Can i cut a hole in the top of the tank to see what is going on then reseal with a plate and some sealent?
Does it not have a sender unit you could remove/
yes its does have a sender but it is only small
As long as you don't use an oxy-torch or plasma cutter yes 
Officially tiger seal and the like aren't fuel proof but don't tell my tank that because I used it as a pseudogasket on the sender unit and it's fine 8 years later...

Can't you just pull the fuel pipe off - if no fuel comes out the tank outlets blocked, otherwise, its the pipe!
If its the tank, twizzling a bit of wire up the outlet hole may sort it, but I'd want to take the tank out, turn it upside down and drain it
properly.
If its the "pipe" - thats everything else as far as the carbs or injectors - may include filters, pumps, swirl pots etc, just find the
'halfway' point and disconnect there, refit tank end and see if the fuel gets there ......
Just a question - do you know if your tank ever had any sealant put in it? I've heard that can come off in sheets after a while - these sometimes
gets sucked over the outlet hole and cause the engine to stop, but it usually restarts once the suction stops.
Obviously you need the best roasting pan from the kitchen to catch the fuel as it pours out!

I think I would try clearing the outlet using a piece of wire etc aqs suggested followed by a good clean internally. If the inside of the tank is dodgy then possibly use a fuel tank sealer from someone like Frosts or Eastwoods
Finally got the outlet clear- Got some wire and hamered it down the pipe, It took some clearing. The car was stood for 20 years so thats why it was
probs so gummed up.
Had a look in the tank through the seder hole and it looks quite good.
tried to start the car today for the first time, It fired but i think i have the coil pack wires back to front going to the edis
