My 1990 syncro doka has an 18+- gallon gas tank, but i have been able to
put 18.7 gallons in it, which means I was completely out of gas when I
pulled into the station, or the pump lied!
That said when filling the tank, the pump shutoff usually stops pumping at
about 13-14 gallons, & then I nurse it to top off the tank/filler neck w/
the above claimed gallonage.

YMMV,

Mr. BZ-fuel pump still works well, so tank must be clean?
