Inline fuel pump vs tank fuel pump

That's the problem I'm talking about I dont wanna drop the money to buy the new tank for inland oil ne fuel pump when I could use the tank I have and just put and inline pump on

Then do it. It'll work fine. Mount the pump as low as possible in relation to the tank. In other words, try and make it a gravity feed to the pump. That way, the pump doesn't work as hard and will last a long time.
