ALTERNATIVE TO FUEL TANK REPLACEMENT 
… Mark Morgan’s suggestion (not yet approved by GFA).... (Feb 02)
Line the the existing tanks with a satin weave cloth and the same resin that Schleicher uses for their fuel tanks in ASW 22, 24, ASH25 and 26.
Schleicher also had a problem with European mogas with the tanks in the ASK 14 and ASK 16 and these tanks had to be replaced with ones made from the current resin.
The details of the lining are..
          Bakerlite L20 resin with H 91 hardener
          Satin weave cloth EW303   (303 grams per sq metre) from FGI

- Metric fuel line brass fittings are hard to get – try using hydraulic
fittings
