You can’t transfer your petrol pump licence directly.
For doing so you have to file for Reconstitution of petrol pump licence. Now to be eligible for reconstitution, your petrol pump should be at least 5 years old and licence should not have been reconstituted for last 5 years (apart from the cases arising from death of proprietorship firm) .
Now apply for reconstitution at your territory/regional office in a prescribed form with all relevant documents, format of which can be collected from your sales officer.
In this reconstitution you can transfer maximum 49% ownership to the incoming party and you will remain minimum 51% owner.
After reconstitution is done get your new partnership firm registered with the same percentage ownership as filled in reconstitution form.
Now wait for 5 more years from the date of reconstitution and go for it again and now you can transfer full 100%.
This is the process to transfer your pump licence.
