Gaza leader Ismail Haniyeh has met Egyptian President Mohammed Mursi in an official visit signalling a shift in Cairo's stance toward the Hamas movement.
Haniyeh and Mursi shared a Ramadan iftar - the meal with which Muslims break their fast during the holy Islamic fasting month.
Earlier, Haniyeh had met chief of intelligence Murad Muwafi, reflecting the role still played by the Egyptian security establishment in managing Palestinian affairs.
The Egyptians said the quantity of fuel supplied via Egypt to Gaza would be more than doubled next week.
The fuel supplied by Qatar goes from Egypt into Israel, from where it passes through a crossing into Gaza in accordance with the existing arrangements on how goods pass into the territory that was captured by Israel from Egypt in a 1967 war.
Israel withdrew settlers and soldiers from Gaza in 2005.
Earlier this year, Brotherhood officials had lobbied for the fuel to be sent straight across Egypt's border with Gaza - a move sought by Hamas and which would have marked a major step towards opening the border to trade and commerce.
In another apparent gesture triggered by Mursi's election victory, Egypt is to ease restrictions on Palestinians travelling through Egyptian territory on their way in and out of Gaza.
Palestinians on that route have complained of mistreatment including detention at their port of arrival ahead of their deportation to the Rafah crossing.
