Rio Haryanto has revealed that his management team are "working very hard" to ensure he spends the full season with Manor.
Haryanto joined the team at the start of 2016 in a pay driver deal but is still short of the funds needed to see out the season.
While the Indonesian government has put down some of the money, Haryanto's team is working on a crowdfunding scheme to raise the rest.
"I hope that I can be here for the full season," GPUpdate.net quotes the driver as having said.
"There are some rumours that I'm only going to do half of the season at Manor, but at the moment my management are working very hard to get the full season.
"I'm focusing on the job and we'll see what happens later."
The former GP2 race winner admits that the on-going uncertainty is weighing on him and as such he hopes to have it resolved as soon as possible.
He added: "It's important to lift that [financial] side of me.
"I've just got to do my best, drive the car as quickly as possible and work with the team well.
"I still believe there is a lot more to come, and to be able to compete with Pascal, and to match him, is a good reference, so I'll just try to keep it up and be slightly quicker again."
