My ‘93 4/4 was 55 litres or 12 gal. Dimensions measured and calculated volume. I was flushing the tank due to crud buggering the pump so did some extras...measured tank, new pipework/pump/extra filter. Also refilled with 1gal to check the gauge reading for reference (it was just touching the “E” with 1 gal.
19 gal seems a huge tank! TOK had a big tank for LeMans but in a production car? WOW!
