The Dutchman was running second behind eventual Australian GP winner Charles Leclerc when he was forced to park his RB18 shortly after starting his 39th lap. 

After the race Horner insisted that there was no connection to the problem that affected both Verstappen and teammate Sergio Perez in Bahrain 

The Australian failure was external to the tank, and as such came under the responsibility of Honda rather than the team. 

“We've been working with our colleagues at HRC in Japan, and they found the issue and they resolved it,” Horner told Sky F1
