If you're going to be running on your current configuration then the stockie is fine. If you go above this, the you'll need an aftermarket pump.
You'll get a mixed reaction as to what sort of pump is best. Some favour Warlbro, others Bosch etc.
But at the end of the day as long as it flows the required amount of fuel needed for your application, then it's doing its job.
Spend your money elsewhere at the moment.
