Fuel Tank Removal

Hi Guys,

I think the fuel tank sender seal (bottom round seal beneath the fuel tank) is knackered as its all saturated in fuel and every time I used the the car there would be the alarming smell of fuel.
I´ve bought some sender unit seals off Mark Gray (UK) so I think I have the right parts but I was originally going to get my local mechanic to change it over as I cant easily access the underneath of the car. My question is, can you remove the tank from the boot, and do I just need to unplug the fuel lines from the sender unit that run to/from the engine (will it all come out with the tank?)
My baby has been stopped for over a month now and I really want to get it sorted out, miss the joy of driving her!
Cheers
Andy
 
You have to go under the car to remove the fuel pipes from the sender to remove the tank, so why not save yourself the bother and remove the sender while you're under there?
 
The fuel pipes look original, very discoloured and I assume they have jubilee clips on the end?
If I can get these out (which may not be tooo hard) then I could attempt at the sender unit but I thought you need a specialist tool to unscrew it? Getting both hands under the car to do this will be tricky. Even unscrewing a jubilee clip screw will be challenging I think.

I may be overthinking it however?
Ive never been keen on getting under the car fully, even with axle stands.....
 
There shouldn't be any jubilee clips (unless the export cars had them) they have proper fittings. There is a special tool to remove the locking ring, but careful use of a hammer and drift works just fine.
 
OK so Hammer and Drift should hopefully work. You say proper fittings, how exactly are the fuel lines connected at the sender end? Can they be prised off easily?
 
They are 9/16 and 5/8, or 1/2 and 9/16 (?) fittings in the same design as where they attach to the carbs.

Theres me thinking this would be a hefty job (car to mechanic, money, time, money etc), and I managed to get it done in an hour and a half today while the kids had their afternoon nap!
Unscrewed straps holding tank down, took the arm off that leads up to fuel cap, wiggled a bit and the thing came out. Also decided to just stick myself right under the car and unscrew the fuel pipes to the sender unit too which wasn't as bad as expected.
Took sender out, gave the tank a quick clean (it was actually surprising clean considering the car stood for 30 years), put new seal on and put it back together again.
Works a treat!
Thanks all for your input.
