Red Bull say they have located and fixed the problem that forced the team into a double DNF at the season-opening Bahrain Grand Prix last weekend.

Reigning world champion Max Verstappen and team-mate Sergio Perez saw their respective challenges falter in the final laps after both suffered mechanical malfunctions.

Ferrari duo Charles Leclerc and Carlos Sainz, along with Mercedes' Lewis Hamilton, instead made up the podium as their rivals were left empty-handed.

But ahead of this weekend's Saudi Arabian Grand Prix, Red Bull revealed they have identified the issue as a lack of fuel pressure late on, and have now rectified the problem.

"The correct amount of fuel was in both cars, but a vacuum prevented the pumps from drawing fuel and delivering it to the engine," said a team spokesperson.

"We've taken the necessary steps to correct this issue and we expect no problems this weekend."

Red Bull will look to get their first points of the season on the board in Jeddah, where Verstappen took a second-place finish behind Hamilton last year.

The race will proceed without Sebastian Vettel, as the Aston Martin driver and four-time world champion continues to recover from COVID-19.
