Pastor, who won the Formula Renault championships last year, was invited by Team Meritus headed by Peter Thomson, who is behind the development of drivers like Baricello and Sato in their early years.
Pastor needs to raise P2-million to compete. Deadline for sponsors pledge has been extended to Tuesday.
"We are counting on the leaders of the government and private sectors to participate in this endeavor, so that the Philippines will again be represented in this very prestigious world-class Formula racing competition where only the chosen few are invited," said his father Tom.
The late Dodgie Laurel was the last Filipino champion to represent the country four decades ago.
