Does anyone have a photo or design of a fuel tank inspection plate?

Thanks.

Wills fuel tank update for what its worth.

The options are

   1. Europa original - waiting for cost and lead time.  I think the new
   design is slightly larger than my tank necessitating the opening of the
   door sills.  The issue with my tank is not the tank - it was the stress
   caused by bonding the tank in place per the manual.  The tank
   material which was fabricated at the latest in 2002 is still fresh and
   flexible (not yellow and brittle).  I did not have my tank fluorinated.
    So those that followed Buds tank installation instructions can take
   comfort from that.
   2. Aluminium - I am a bit intimidated by the complexity of the tank
   shape.
   3. Composite:  my research suggests ethanol is a problem for composite
   tanks and therefore the resin is critical.  So far I see two options:  EZ
   Poxy which is sold by ACS and used in aircraft which use composite tanks
   and MAX GRE which is sold specifically for fuel tanks.  There is also
   Isophthalic Resin which is used for underground gasoline storage in gas
   stations.  Either way I need an inspection plate in order to check the
   state of the resin.  I see a couple of advantages to building the tank.  It
   will fit.   I can adjust the filler and outlets.  It could be slightly
   larger.  Finally I can include internal reinforcement to stop bulging.  Set
   against this is the issue of crash resistance.   The HDPE tank is
   tough...very tough.  I suspect that a composite tank would fracture.
