[Mgs] Fuel Tank Sender unit replacement

[Charley & Peggy Robinson]

Yep, I replaced the s-unit in my '69 B a couple of months ago, had the 
same problem.  It's a good idea to have a new locking ring on hand as 
you may destroy the old one getting it out if it's really stubborn; also 
a new gasket.  I squirted penetrating oil around the ring, tapped the 
ring with a punch & hammer to unseat it in the flange, squirted more oil 
on it and left it overnight.  The next morning I started tapping it out 
CCW.  Just had to keep worrying, it tapping on each prong.  You have to 
keep your punch down toward the bottom of the prongs.  If the prongs 
bend or shear off, don't despair.  They are just the extension of an 
inclined flange bent into the ring.  You can get at the bottom of the 
bend with a smaller punch or a small blunt chisel.  Get a new ring and 
you'll see what I mean.  The only thing holding it all together is friction.
