CREATE TABLE table_50729 ("Driver" TEXT, "Team" TEXT, "Laps" FLOAT, "Time/Retired" TEXT, "Grid" FLOAT)

What were the highest laps when the grid was larger than 19 and the time/retired was fuel?
SELECT MAX("Laps") FROM table_50729 WHERE "Grid" > '19' AND "Time/Retired" = 'fuel'
SELECT MAX("Laps") FROM "table_50729" WHERE "Grid" > '19' AND "Time/Retired" = 'fuel'
